Renewable energy With the climate change crisis now officially dovetailing out of control, there has never been a greater call for renewable energy investment. The global reliance on oil and gas needs to stop, this much was driven home by the invasion of Ukraine last year and the subsequent energy crisis it catalyzed. But while oil and gas still account for more than half of global energy consumption, there is definitely a positive change happening.   This change is being spearheaded by certain industries and technologies that have a futureproof mindset. Here, we’ll be spotlighting a few of these sectors. Artificial intelligence   AI is having a major transformative impact on most industries but not in the ways you might think. We’ve all been led to believe by decades of speculative science fiction that AI will replace us but it’s actually being used in a more benevolent capacity. In terms of renewable energy it’s being used to forecast demand to ensure minimum waste, which is very important with renewable resources that can’t be stored for as long as oil and gas. The cleverer this AI gets, the more gains can be made and the easier the transition to clean energy will be. Green hydrogen energy   While burning hydrogen is a green process, in theory, converting it into fuel can be a very environmentally unfriendly activity. A green hydrogen pipeline, however, such as the one Shell and RWE have already committed to building in Europe, uses electrolysis and water in a manner that renders the process completely carbon-free. This pipeline isn’t expected to be completed until 2035 but there are other movements being made in the green hydrogen field such as the hydrogen powered electric bike and the hydrogen powered electric car charger. The Internet of Things   The IoE refers to networked devices sharing information and working together to achieve a goal. If you have an Amazon Echo in your home then you are using IoE technology. As this technology advances, however, more utility companies will be able to connect their data centers to their power sources, helping in everything from efficiency to experience. Advanced engineering in renewables   The technology underpinning renewable energy is always improving. We are seeing particular gains being made in the solar and wind markets, where once expensive parts such as computerized components and torque sensors can now be produced and bought for a fraction of the cost a few decades ago. This is only going to get better the more time moves on too! Bioenergy Imagine if we could turn unwanted crops or even our waste into energy? With bioenergy, it might not be as farfetched as you might think. The process of converting biomass into energy is in its infancy right now but major companies such as Heineken have already begun using bio waste as fuel. The future of energy might just well be in our toilet waste!

Technology smaller but more efficient Increasingly efficient and increasingly compact – technology is shrinking. Bulky phones, computers and TVs are no more. Instead, we have slick devices that can process and hold more data than ever before. Devices have become significantly slimmer and more portable compared to the late twentieth-century. But how did this all come about? Here’s how technology has shrunk in recent years. How technology has shrunk Portability has been an important motive for shrinking technology. Almost all of us carry a phone when we leave the house and many also carry tablets or laptops, while wearing headphonesor smart watches. Chunky plugs and wires have been replaced by Bluetooth and portable charging amongst other things.This opens up a world of possibilities while people are on the move. You can contact a friend, track your daily activity, watch videos online – shrinking technology has made this possible. Computers The magic tool here is the silicon computer chip, alongside the shrinking size of transistors. We all remember the days when computers were huge and weighed an absolute ton. Add in ultra-slim monitors and things are a whole lot mor portable now.Computers are significantly more affordable too, to the extent that people use them at home for personal use, rather than exclusively in the office. Portable technology Storing as much data as possible using as little space as possible is the goal to facilitating portable technology. STT RAM (Spin Transfer Torque Random Access Memory) have contributed massively to this. Laptops, tablets and even our phones have eased us away from sitting at a desk and using a desktop computer. These new ways of accessing a computer-like system can also be used to help combat the UK’s digital divide, by issuing schools with portable technology to help improve learning. Smart TV’s Long gone are the inefficient, energy-gobbling television sets of the past. Today, TVs are leaner and greener, with many energy-efficient options on the market in a neat, slimmed-down model. These are operated with remote controls powered by long lasting AAA batteries. They’re smart too, enabling you to stream content from the web and platforms, which again, allows you to achieve far more from your viewing experience that goes beyond classic satellite TV. IoT and cloud computing The Internet of Things (IoT) has changed the way we consume content as we know it. It refers to devices that gather and share information across different industries. The interconnectivity between this and Cloud Computing, which helps to store IoT data, means that people can enjoy a better experience.While many technology advances have enhanced user experience, it has also caused some devices to become obsolete. Music players such as cassettes, CD players or MP3 players have been wiped out by music streaming platforms, from Spotify to Apple Music. An anomaly in this has been the resurgence of vinyl.

Selenium Java automation plays a pivotal role in the field of software testing, automating repetitive tasks, conducting regression testing, and ensuring the functionality of web applications across various browsers and platforms. Its versatility and power have made it an essential tool for testing teams worldwide. However, while Selenium automation testing offers numerous advantages, it is not without its challenges and pitfalls. In this comprehensive guide, we will delve into some of the most common mistakes that testers and developers make when using Selenium with Java, and we will provide guidance on how to avoid these pitfalls. From the initial planning stages to robust error handling, we will cover essential aspects of Selenium Java automation testing best practices. Lack of Planning Effective planning is the foundation of any successful automation project. Without proper planning, you risk wasting valuable time and resources. Common planning mistakes include insufficient requirement analysis, unclear project objectives, and inadequate test case design. To avoid these issues, it is crucial to start with a well-thought-out plan. This plan should encompass a deep understanding of the project’s goals, comprehensive requirement analysis, and the creation of a test strategy that outlines how automation will support the overall testing process. By investing time in planning, you set the stage for a smoother and more successful Selenium automation project. Poor Element Locators Selecting robust and reliable element locators is undeniably a cornerstone when it comes to creating stable and maintainable automation scripts in Selenium Java. Element locators serve as the virtual GPS, guiding your automation framework to identify and interact with specific elements on a web page accurately. However, choosing the wrong locators can lead to brittle and unreliable tests, turning your automation efforts into a frustrating endeavor. Common Mistakes in Locator Selection Several common mistakes plague automation engineers when it comes to selecting element locators: Over Reliance on XPath Expressions: XPath is a powerful tool for locating elements, but an excessive dependency on complex XPath expressions can make your scripts convoluted and prone to breaking when the page structure changes. Dependence on Auto-generated IDs: While auto-generated IDs may seem convenient, they often lack stability and can change dynamically, causing your automation scripts to fail unexpectedly. Non-Unique Locators: Using non-unique locators, such as selecting elements based solely on their class names or tag names, can lead to ambiguous identification and unreliable automation. Enhancing Your Element Locators To bolster the reliability and resilience of your element locators, consider the following best practices: CSS Selectors: CSS selectors are a robust alternative to XPath expressions. They offer more straightforward and concise ways to locate elements based on their attributes, making your code more readable and maintainable. Leverage Unique Attributes: Whenever possible, select elements based on unique attributes like IDs or custom data attributes. These attributes are less likely to change and provide stable reference points for your automation. Dynamic Locators: Embrace dynamic locators that adapt to changes in the web page structure. Using relative locators, such as locating an element based on its relationship to another nearby element, can make your scripts more resilient to UI changes. Thoughtfully crafting your locator strategies can significantly enhance the stability and maintainability of your Selenium tests, reducing the likelihood of test failures due to changes in the application’s user interface. Inadequate Synchronization Synchronization is a paramount aspect of Selenium automation, ensuring that your tests interact with web elements precisely when they are ready and in the correct state. Neglecting synchronization can result in flaky tests, where the timing of interactions becomes unpredictable, and automation becomes unreliable. Common Synchronization Pitfalls Several common synchronization mistakes plague automation scripts: Improper Use of Explicit Waits: While explicit waits are a powerful synchronization mechanism, using them improperly, such as setting excessively long wait times, can slow down your test execution and make your scripts less responsive. Hardcoded Sleep Statements: Relying on hardcoded sleep statements can introduce unnecessary delays into your tests, and they are not an efficient way to handle synchronization, as they may lead to longer test execution times than necessary. Handling Asynchronous Operations Ineffectively: Web applications often involve asynchronous operations like AJAX calls. Failing to handle these operations effectively can result in test failures or unreliable test outcomes. Implementing Effective Synchronization To conquer these synchronization challenges, it is essential to implement proper synchronization techniques: WebDriverWait and ExpectedConditions: Use WebDriverWait in conjunction with ExpectedConditions to define specific conditions that must be met before your automation proceeds. This allows your tests to wait for elements to become clickable, visible, or any other condition you specify, ensuring that your interactions occur at the appropriate time. Asynchronous Operation Handling: Be vigilant in handling asynchronous operations like AJAX calls. You can use WebDriverWait to wait for these operations to complete before proceeding with your test steps. This prevents timing issues that can lead to flaky tests. By implementing these synchronization strategies, you ensure that your Selenium tests are robust and resilient to timing-related issues, providing reliable results even in the face of dynamic web pages and asynchronous operations.   Neglecting Error Handling Effective error handling is often an afterthought in automation scripts, but it is a crucial component of reliable test automation. Neglecting error handling can result in unreported issues, making it challenging to identify and address problems promptly. Common errors in this area include ignoring exceptions, not providing meaningful error messages, and failing to log errors adequately. To improve error handling, consider using try-catch blocks to catch and handle exceptions gracefully. Additionally, integrate a logging framework into your automation framework to capture and log errors along with relevant context information. Proper error handling ensures that your automation scripts continue running smoothly, even in the face of unexpected issues. Unoptimized Test Frameworks A well-structured test framework can significantly enhance the maintainability and scalability of your automation project. However, many projects suffer from suboptimal test framework designs. Common framework-related mistakes include a lack of modularity, tight coupling between test cases and implementation, and inefficient test data management. To optimize your test framework, consider adopting design patterns

With so many programming languages to choose from, it can be tough to decide which is best for a given task. Java and Python are often used with the popular web application testing framework Selenium. Both have their own strengths when paired with Selenium for automation testing. As more companies adopt Selenium for testing, many are trying to determine if Selenium Java or Selenium Python is the better match.   This article compares Selenium Java and Selenium Python to highlight the pros and cons and help you determine which language works best with Selenium.   Defining Python and Java: Scripting vs Programming Language A key question when contrasting Python and Java is whether they are scripting or programming languages. This distinction influences factors like speed, flexibility, and learning curve.   Fundamentally, all scripting languages are types of programming languages. The critical difference lies in how they execute code. Programming languages first compile source code to platform-independent bytecode. This bytecode can run fast via interpretation as Java does on its virtual machine.   In contrast, scripting languages directly interpret source code line-by-line. The lack of a compilation step enables greater dynamism and rapid prototyping. But it sacrifices execution efficiency versus compiled code. Python Python blurs the lines between scripting and programming languages. It can work as both a compiler and interpreter, making it very versatile. While Python is primarily considered a general-purpose programming language, it also functions seamlessly as a scripting language.   An interpreter acts as a bridge between the program code and the system hardware, executing the code line-by-line. The Python interpreter specifically runs Python scripts, compiling Python code into bytecode and then interpreting it, similar to Java and C. This dual compiler/interpreter functionality allows Python to be used for both scripting and traditional programming. Java Java contrasts as a traditionally compiled language. It transforms source code into optimized bytecodes for the Java Virtual Machine (JVM). The JVM then interprets these artifacts at high speed. So, while Python embeds an interpreter, Java offloads this responsibility to its runtime platform. This compilation strategy provides fast and consistent execution critical for large programs. The tradeoff is Java enforces type-checking and other constraints early on. This makes Java code more verbose and restrictive but boosts structure and robustness. Comparing the Learning Curve When deciding which programming language to learn first, many beginners wonder how quickly they can master Java versus Python. There is no doubt that Python has a clear advantage when it comes to learning speed. Python’s syntax is more concise and easier to grasp than Java’s more complex and restrictive code requirements. If you need to get up to speed with a new language fast, Python is likely the better choice.   However, there are several other key factors to weigh when choosing between Java and Python: Job Opportunities – Java development jobs are still more plentiful than Python jobs, so Java may open more career doors initially. Career Changes – Thanks to its versatility for scripting, Python provides an easier transition if you later shift into a field like DevOps. Java is more siloed in traditional software engineering roles. Object-Oriented Design – Both Java and Python rely on object-oriented programming, so learning one provides a solid foundation for picking up the other. The core OOP concepts transfer between the two languages. Platform Independence – Java bytecode and Python bytecode can both run on any supported platform due to their virtual machines (JVM and PVM). This makes them portable and widely usable. Simplicity – Python’s minimalist and intuitive syntax allows beginners to start building programs more quickly than in Java. Java’s verbose coding style has a steeper initial learning curve. Execution – As an interpreted scripting language, Python code can run immediately line-by-line. Java requires ahead-of-time compilation before execution, adding complexity. Performance – Compiled Java applications execute faster and more efficiently than Python-scripted programs. Popularity – Java and the JVM are used much more broadly across the industry than Python. Thus, Java has a larger ecosystem of supporting tools, libraries, and a wider community. Static vs. Dynamic Typing – Java uses static typing, so type errors are caught at compile time. Python uses dynamic typing, so errors show up later at runtime. In brief, Python is easier and faster to learn, while Java opens more career opportunities. Consider what trade-offs matter most to you when deciding between the two programming languages. Why is Python with Selenium a good option? Python paired with Selenium is a powerful and versatile option for test automation. Here are the reasons why Selenium Python is a good choice:   Python is an open-source, high-level, user-friendly scripting language that is easy to learn and interpret. Its simple syntax and English keywords help testers ramp up quickly compared to other programming languages. Python can be used across a wide range of applications – web, mobile, network, GUI, games, etc. This flexibility allows testers to leverage their Python knowledge across many types of test automation projects. It is fast, both in terms of script execution speed and developer productivity. Its efficient runtime and concise coding style mean tests run quickly and can be coded rapidly. Python code is readable and maintains a clear, logical flow by using indentation instead of braces for denoting blocks. This results in code that is easy to understand and maintain. Python is dynamically typed and less verbose than many other languages, making test code more compact and focused. Less coding clutter means simpler test logic. Python offers easy integration with Selenium through native API bindings. Browser automation capabilities are built right in. Python removes the compile step as an interpreted scripting language, allowing for agile test execution and iteration. Changes can be tested immediately. The strong WebDriver bindings with Python Selenium make browser test automation highly flexible and easy to integrate.   Python with Selenium combines the strengths of an accessible language with a leading web testing framework. Developers who leverage these tools can maximize productivity and minimize test creation effort. Why

Parameterization, also known as parametric testing, is a vital technique in TestNG for automation testing of application behavior against multiple data values and configurations. While exhaustive testing with all user data permutations is impossible, validating how the application handles different input combinations that end-users may provide in production remains necessary. Running automated tests repeatedly with a range of test data values allows for identifying defects missed by any single hardcoded dataset.   However, manually coding myriad test data directly in test scripts is laborious, error-prone, and leads to poor maintenance. TestNG alleviates this problem effectively through inbuilt parameterization features tailored for test automation. TestNG parameterization provides a robust mechanism for essential automated, data-driven testing scenarios.   This article will explore how to parameterize the TestNG dataprovider with different data sources, such as Excel, JSON, or databases.   What is TestNG DataProvider? The DataProviders in TestNG allow passing multiple parameters to test functions in a single execution. Data Providers are annotated with @DataProvider and return test data as a two-dimensional object array. Using DataProviders, TestNG tests can intake parameters differently, enabling data-driven testing. DataProviders can be declared within the test class or created in a separate file, then referred to with annotations from test methods.   The DataProvider annotation differentiates these methods from others. When executed, DataProviders will feed various values into TestNG test cases, facilitating parametrized tests with a single run. Benefits of Using TestNG DataProviders Over Traditional Parameterization Approaches The traditional technique involves passing parameter values from XML config files, allowing only a single data set per test run. This proves limited for running the same test logic on multiple data ranges, a standard testing need.   TestNG DataProviders overcome this effectively by: DataProviders allow declarative annotation-based injection of multiple parameter inputs into a test method within a single test run. This enables efficient data-driven testing by running the same test logic repeatedly with different data. DataProviders promote simpler coding over XML since test data is specified directly in the test code via annotations instead of external files. They also facilitate dynamic parameterization and re-execution of tests at runtime versus the static nature of XML test parameters. The DataProvider syntax is less complex overall compared to traditional test parameters. DataProviders enable essential test scenarios like parameterized and data-driven testing that XML parameters cannot achieve. Using a tool like LambdaTest that integrates with TestNG enables seamless distributed execution of DataProvider-driven tests across browsers and environments for enhanced cross-browser testing. LambdaTest is an AI-powered test orchestration and execution platform that lets you run manual and automated tests at scale with over 3000+ real devices, browsers, and OS combinations.   DataProviders facilitate essential test scenarios like data-driven, parameterized testing, which traditional XML parameters could never achieve. Their capacity to feed various inputs into test methods without needing multiple test runs makes them far more powerful and versatile. How to Use TestNG Dataprovider with Excel? Excel spreadsheets serve as handy delimited data sources for feeding test data into TestNG test methods via dataprovider annotations. We construct an integration framework that enables externalized and reusable test datasets by leveraging lightweight Java libraries like Apache POI to access Excel contents programmatically. The workflow involves three simple steps: Design Test Data Sheet We lay out the dataset as a grid within an Excel workbook, defining columns to match the parameter order/types needed by the test methods expecting injection. Additional metadata like test case IDs or categories can guide reporting. Serialize Sheet Contents Next, we extract the sheet data at runtime. The Apache POI API provides helpful utilities like XSSFWorkbook and XSSFSheet for ingesting Excel contents into in-memory models. We traverse rows or cells using iterator style access, capturing into parameter array objects. Invoke Dataprovider Finally, our custom dataprovider method returns the extracted Excel-derived arrays, with @Test methods accessing rows as test iterations via input parameters. The testdata provisioning resides separately from the executing test body.   The Excel integration reliability, accessibility, and interface familiarity unlocked by Apache POI combined with TestNG dataprovider annotations provides a smooth conduit for consumerizing test data and accelerating test creation. With thoughtful design, we tame complexity. How to Use TestNG Dataprovider With JSON? JSON (JavaScript Object Notation) has become a ubiquitous data format for storing and exchanging information across systems and platforms. With its lightweight structure, readability for humans, and ease of parsing for machines, JSON acts as an ideal data source for testing applications.   TestNG DataProviders empower data-driven testing by allowing test methods to dynamically receive inputs from various sources at runtime. Enabling DataProviders to consume test data from JSON files combines the strengths of the two approaches.   Through a few simple steps, JSON test data can be fed into TestNG test methods efficiently using DataProviders:   Add a JSON Parser First, ensure a JSON parser like Jackson or GSON is available in the classpath. These libraries can read JSON content and convert it to Java objects like Maps, Lists, etc., which TestNG can use easily. Create DataProvider method next, create a DataProvider method to retrieve data from the JSON source. This would use the parser to deserialize JSON content to Objects[] or Collection of Objects and return the same. The @DataProvider annotation indicates this is not a regular method. Supply data to tests decorate test methods will consume JSON test data with the DataProvider reference. TestNG will execute those methods repeatedly, passing the datasets returned by the linked DataProvider. Any JSON attributes can be accessed within tests via the passed Objects. Parameterize for modularity for improved structure; tests should accept parameters instead of tightly coupled JSON objects. TestNG will pass individual data items from JSON arrays as parameters to test methods.   TestNG handles all the complexity of repeatedly executing tests and routing JSON data to test code behind the scenes. Configuring JSON DataProviders mainly involves one-time tasks like adding parsers and writing provider methods. This approach optimizes data-driven testing with easy maintenance of test data in JSON files external to test code. How to use

Automated Software Testing frameworks provide the foundation for writing and executing automated tests as part of software quality assurance. TestNG and JUnit are the most widely used test automation tools in the Java ecosystem. Both frameworks allow testers to write test methods, organize them into classes, execute tests, and report the results.   The core purpose of both TestNG and JUnit is to enable automated testing of code units, APIs, user interfaces, or whole systems by providing the necessary test organization and execution capabilities. This article will comprehensively compare TestNG and JUnit across various parameters to help decide which framework better meets your automation needs.   What is JUnit? JUnit is an open-source unit testing framework for Java that has become the industry standard for testing Java applications and verifying small code sections. As an implementation of the xUnit architectural pattern for unit testing frameworks, JUnit promotes readable and repeatable testing practices.   JUnit facilitates writing repeatable and automated tests that can be executed anytime. Its annotations, like @Test, @Before, @After, etc., provide a standardized structure to write clean and easily readable test cases. The ability to automate the execution of these test cases seamlessly integrates JUnit with build tools like Maven and IDEs like Eclipse. This enables continuous testing without manual intervention, saving considerable time and effort during development cycles.   JUnit tests are typically written for small code units to validate their behavior. Any bugs manifest themselves as failing tests immediately after changes are made. This pinpoints the root cause faster and makes debugging efficient compared to finding defects later through manual testing. The separation of failing and passing test cases guides the developer to focus only on the problematic areas.   JUnit promotes test-driven development (TDD), i.e., writing tests even before the actual business logic. The failure of initial test cases drives the implementation. This results in modular, flexible, and well-tested code with minimal defects. The availability of assertions like assertEquals(), assertTrue(), etc., makes writing test cases simple and intuitive.   JUnit’s extensible architecture is another key benefit. It can be easily integrated with frameworks like Mockito, Selenium, Cucumber, etc., to enable integration testing, behavior-driven development, and UI testing. This expands the scope and capability of JUnit significantly. What is TestNG? TestNG is an open-source automated testing framework for Java that builds on and extends the capabilities of the JUnit framework. The “NG” stands for “next generation,” indicating its focus on advancing test automation for Java.   TestNG covers a broader scope of test types than JUnit, including unit testing, functional testing, integration testing, end-to-end testing, and more. It helps organize test cases clearly and maintains readable test scripts.   Some key features of TestNG: Annotations – TestNG provides annotations like @Test, @BeforeMethod, @AfterClass, etc., to define test cases and set up the test environment. This makes tests more readable and maintainable. Test grouping – Tests can be organized into groups, which can then be executed separately. This allows flexibility in test runs. Test parametrization – TestNG allows passing parameters to test methods through the XML file. This facilitates data-driven testing. Dependent tests – Tests can be made dependent on other tests, enabling prioritization of test execution. Parallel execution – Tests can run parallelly, significantly reducing overall test execution time. Flexible test configuration – TestNG provides XML files to configure tests and suites flexibly with control over ordering and grouping. Extensive test reports – Rich HTML test reports are generated with details about passed, failed, and skipped tests.   TestNG introduces a simplified test authoring process compared to older frameworks. It also handles dependencies between test methods automatically for more robust test runs. You can leverage online cloud-based platforms such as LambdaTest to enhance the capabilities of TestNG. LambdaTest is AI-powered test orchestration and execution platform that allows businesses to run automated tests, cross browser testing over 3000+ test environments, including real devices cloud. Difference between TestNG and JUnit To find which framework is best for Selenium automation—JUnit or TestNG—let’s first examine the differences. Test Suites Test suites allow grouping a set of test cases and running them together. TestNG has built-in support for defining test suites in XML configuration files and running them. The XML contains details about which test classes and methods belong to a test suite. This allows for executing groups of related tests together.   In contrast, JUnit did not initially have the concept of test suites. It was introduced in JUnit 5 later on. JUnit uses annotations like @RunWith and @Suite to define suites in Java code. So, the test classes have to be wired up together in code.   The XML-based approach of TestNG works better for most testers as there is a cleaner separation of test code and execution configuration. Also, TestNG provides more flexibility in terms of executing multiple suites, tests in different threads, reporting at different levels, etc. Annotations Both JUnit and TestNG use annotations to decorate test methods, setup/teardown logic, etc. This allows the framework to recognize the methods meant for specific purposes. The annotations between both frameworks are quite similar in function but differ slightly in name.   The naming conventions differ slightly between the two frameworks, requiring some learning when switching. But they serve the same purpose. JUnit Annotations   @Test This annotation denotes that a method is a test method. JUnit will run all methods annotated with @Test. @BeforeAll Applied at class level. Denotes that the annotated method should run before all test methods in the current class. Useful for expensive setup tasks. @AfterAll Applied at class level. Denotes that the annotated method should run after all test methods in the current class. Useful for cleanup activities. @BeforeEach  Denotes that the annotated method should run before each test method is executed. It is commonly used to set up pre-conditions for each test. @AfterEach Denotes that the annotated method should run after each test method is executed. It is commonly used to clean up activities after each test. @Tag Used to declaratively add tags

As organizations embrace the revolutionary power of RPA (Robotic Process Automation), the journey also comes with a set of challenges and potential pitfalls, mainly concerning the risks related with automation. Assessing risks in RPA projects isn’t merely a precautionary step; it is a strategic move to ensure the security, success, and resilience of automation initiatives.

Let’s explore key pointers to confirm a secure and compliant automation journey. Identify Your Automation Scope and Objective Before diving into automation, you need to define the scope and goals of your automation project. What procedures are you going to automate, and why? What are the projected advantages and results? What are the potential threats and effects of automation on your customers, business, and stakeholders? Detect processes suitable for automation, considering factors such as data sensitivity, complexity, and criticality. By answering these queries, you can prioritize the more feasible and valuable automation prospects, and avoid unnecessary or risky ones. This initial step lays the foundation for a risk-aware and targeted automation strategy. Scrutinize Your Data Sources and Flows Comprehensive data analysis and flow are critical. Determine the sources of data that automation procedures interact with and examine data flows. Understanding potential vulnerabilities and data dependencies confirms data integrity and mitigates risks related to improper data handling. It is crucial to implement security measures and controls to protect the data they handle from malware, cyberattacks, or human errors. Encrypting data at rest and in transit, using secure authorization and authentication mechanisms for data access, applying the norm of least privilege and segregation of duties for bot responsibilities and roles, auditing and monitoring, and data activities and logs, updating and patching software and dependencies, and implementing recovery backup plans for data failures or disasters are all best practices to guarantee your safety. Execute Security Controls & Measures One of the main security and compliance concerns of Robotic Process Automation is data safety and protection. Security should be the foundation of your automation strategy. Your bots will access, process, and accumulate confidential and sensitive information, such as medical records, personal information, or financial transactions. You need to scrutinize the data flows and sources involved in your automation procedures and find the data types, locations, owners, formats, and users. You also have to map out the data lifecycle, from formation to removal, and confirm that your bots follow the data governance standards and policies of your organization and industry. Execute robust security controls throughout the automation lifecycle. Encryption, secure coding practices, and secure access controls are essential elements. Regularly assess and update security controls and measures to stay resilient against growing threats. Align Your Automation with Compliance Requirements Depending on your industry and jurisdiction, ensure your RPA projects

With the introduction of Automation Testing, various new testing processes have improved the accuracy and productivity of the testing infrastructure. Some of the notable mentions in this list include automated visual regression testing, automated cross-browser testing, and automated performance testing.   In recent times, integrating artificial intelligence with test automation has further boosted the productivity and reliability of the entire application development life cycle. For instance, now, the test cases can automatically adjust themselves according to the changing parameters and requirements of the testing cycle.   So, with this article, we are going to explore some of the major advancements in AI-powered automation testing. We will also discuss some of the primary integrations that can help app developers and testers improve the productivity of their overall application development and testing environment.   Exploring the Basics of Automation Testing   For general knowledge, automation testing is a modern software testing technique that utilizes automated tools and scripts for performing tests on a software application. The main objective of automation testing is to increase the effectiveness, efficiency, and overall coverage of the software testing process.   Let us now glance through some of the basic ideas relevant to the automated testing process:   Objectives of Automation Testing   Automation testing aims at improving the efficiency of the testing process by conducting the test cases faster than manual testing.   Using this advanced testing process, the developers can also ensure that the test cases can be repeated to improve the consistency of the test results.   Using this process, the testers can quickly check whether any new code change negatively impacts the functioning of the existing elements of the application.   Using automation testing, the application testers can execute multiple test cases simultaneously on different configurations and environments.   Categories of Automation Testing   The basic category of automation testing involves separating all the elements present in the application into individual entities known as units. Unit testing is the simplest form of automation testing as it tests all the components in isolation.   Using integration testing, the developers can check the proper integrity of different components or systems present in the application.   Functional testing aims at verifying the functionality of the application as per the specified requirements or the intentions of the app developing company.   Using regression testing, the developers can ensure that new code does not impact the functioning of the existing code in the application architecture.   Performance Testing aims at validating the performance of the application on multiple devices and use cases. It also assesses the scalability and responsiveness of the application infrastructure.   Using load testing, the developers can analyze how the application behaves to unusual traffic or certain specified load conditions.   The developers can verify the reliability and functionality of the application programming interface using automated API testing.   Finally, using user interface testing, the developers can automatically verify the graphical user interface for responsive errors, misplacement of UI elements, and other functional issues.   Automated Testing Tools   Selenium is one of the most popular names in the segment of automated testing tools. Using this test suite, the developers can automatically verify the functioning of modern web applications.   Appium is another popular name in this segment and is used for running automated testing on mobile applications across multiple platforms like Android, iOS, and Windows.   Using Jenkins, the automation testers can access an open-source server for continuous integration and continuous delivery.   Cucumber supports the execution of behavior-driven development along with plain text descriptions.   Best Practices for Automation Testing   Before executing automation testing, it is crucial to clearly define the objectives, scope, and criteria for the testing phase.   The developers need to choose the correct testing instances that can benefit from this process. Some of the initial options include repetitive test cases that are time-consuming or critical for automation.   It is a good practice to use external data sources to provide random data sets crucial for executing the test cases.   It is important to regularly maintain the test cases and ensure that they align with the application changes. The developers should also include automation testing with the CD/CI pipelines for a faster feedback cycle.   What is AI-Based Automation Testing   AI-based automation testing involves the integration of machine learning and artificial intelligence with the process of software testing and test automation. Using this approach, the developers can use intelligent algorithms to enhance various aspects of the testing cycle. This can range from designing the test cases and executing them to analyzing the results and maintaining the test cases.   The primary objective of this advanced testing process is to make the testing process more efficient, adaptable, and accurate based on the dynamic nature of modern software apps.   Let us now understand some of the critical areas of automation testing that are directly influenced by the integration of artificial intelligence:   ●      Test Case Generation   Using artificial intelligence algorithms, the system can analyze the application behavior, user interactions, and historical data. This approach will help automatically generate test scripts and reduce the manual effort of designing the test cases.   ●      Test Execution and Analysis   Artificial intelligence can adapt test execution based on the application changes. So, it can identify and execute the relevant test cases in response to all these modifications in the application source code.   Moreover, using AI algorithms, the system can detect and address changes in the application. It can also automatically update the test scripts to match the modified elements in the application.   ●      Managing Test Data   AI can assist modern automation testers in creating diverse and realistic test data for optimizing the testing process and improving the overall test coverage.   Using AI, app-developing companies can also mask sensitive information during the testing process for complying with the data protection regulations.   ●      Defect Prediction and Analysis   AI algorithms can analyze historical test data to

Mobile test automation is associated with the Appium most of the time. There are reasons for that. Appium is an open-source, easy-to-use, and much more efficient mobile app testing tool. It is the most preferred testing tool by software application developers and testing teams. Appium can be used to perform mobile app testing for both Android and iOS. Appium also supports most of the popular programming languages and many types of operating systems.   Parallel testing makes your mobile app testing faster, and multiple test sessions can be held simultaneously. Due to the growing competitiveness, a quicker time to market (TTM) has become crucial for any organization to compete in the market today. And Appium is capable of meeting this requirement.   In this article, first, you will see a brief introduction to Appium and its various aspects. Then, you will see how to incorporate parallel mobile app testing with Appium for better results. What is Parallel Testing? Parallel testing is defined as a software testing process in which multiple apps or features are tested simultaneously, resulting in reduced time consumption of the testing process. It is mostly done when a new version is released for an application. Many types of cloud-based tools and frameworks can be used to perform parallel or distributed test automation on the cloud.   The purpose of parallel testing is to determine if the legacy version and new version behave the same or differently and ensure whether a new version is more efficient.  Parallel testing with Appium for mobile app testing on the cloud is time-efficient and provides better testing results.   Any testing expert should prefer automated tools that function on a cloud to allow for correlation. By testing on a cloud like LambdaTest, the testing experts reduce the number of manual tests and get more access to various hardware options. LambdaTest is an AI-powered test orchestration and execution platform to run manual and automated tests at scale. The platform allows you to perform real-time and automation testing across 3000+ environments and real mobile devices.   Generally, two or more parts in parallel testing are used to check the features and functionality of an application separately. Unlike traditional testing processes, where you must execute each test individually, parallel or distributed testing allows you to run multiple tests simultaneously. Parallel or distributed testing accelerates your release cycles, resulting in fast and more accurate testing results with minimal effort. Advantages of Parallel Testing in Mobile App Testing for Faster Results Let’s look at some of the benefits of parallel testing for the mobile application process.   Better Development Flow: Parallel testing in mobile app testing is essential to the software development process. It allows the developers to share the test results with all the stakeholders. Using parallel testing also helps to boost CI (continuous integration) efforts. This effort helps the developers and QA team save time and deliver the software in the given time period. Parallel testing helps developers to communicate efficiently and the communication between the QA team and developers as the testing and reporting is done promptly, and this results in the better development flow of the software application.   Better Test Coverage: Test coverage is defined as the various configurations, types of devices, and device browser-OS combinations for which you can test your mobile app. The testing coverage increases when you perform software testing using parallel or distributed testing on more and more devices simultaneously. It also helps to ensure that the software experience increases and the end user gets the best possible experience while using the software application. Thus, using parallel testing for mobile app testing helps to deliver a better software experience, which means better ROI.   Time Efficient: Parallel testing helps software developers save time, and that saved time can be used to perform exploratory testing. Suppose you are performing a parallel test of your application on two devices; your testing speed needs to increase by two times. Also, there are chances of human error that may give you incorrect data, so using parallel testing for repetitive testing is recommended, which can also be boring.   Less Script: When you use parallel or distributed testing for mobile app testing, you just need to write the test scenarios once, and you can use them many times. Then, these test scenarios get replicated in another version and on other devices. You can install older and new versions of your software applications on various devices to check compatibility and software consistency. The aim is to ensure that the new version of the software application works well in the new versions and that the existing features and functionality work well. Parallel Testing with Appium for Faster Results You have seen the various aspects of parallel testing execution and Appium. Let us see how you can perform parallel testing with the Appium mobile app testing tool. You will see two designs that you can use to execute the parallel tests using the Appium tool. The first method is parallel testing using the client side, and the second is parallel testing using the server side. Let us discuss them one by one. Parallel Testing using Appium – Client Side There are many options that a QA team and developers can choose for the parallel test execution using Appium. But regardless of this factor, one major part must be tackled with precision and accuracy. It is the client side. You can not say you are executing parallel testing because you have multiple Appium servers on the cloud. You also need a way for your test runner or framework to kick off the tests in parallel. The feature to run testing scripts in multiple sessions or threads at a time is not a part of the Appium tool. You need to configure this in the runner itself. All the programming language and test runners have their approaches to completing the task execution process. The Java language is very popular, so the most preferred choice for this testing
