What is selenium testing?

Selenium is an open-source set of tools and libraries for browser automation. Selenium is used to allow users to test their website’s functionality on different browsers. It is also used to check consistency across different browsers. Selenium can be integrated into multiple tools and frameworks and is highly adaptable. It provides a single interface that helps to write test scripts in programming languages.

The code created using Selenium interacts with the browser in the same way that an average user would on any website, which allows one to locate components on the page and execute actions like clicking links or filling out forms. Selenium provides various benefits, including the ability for developers to rapidly and simply construct test scripts that can be performed multiple times without the need for manual involvement.

Components of selenium

Selenium is not just a single tool; it is a software suite that caters to an organization’s many testing needs. It has three major components:

• Selenium Integrated Development Environment: Testers may record, edit, and debug tests with this browser extension. It is intended to be a straightforward, easy-to-use tool that enables testers to quickly write scripts without having to know much about programming.
• Selenium WebDriver: Selenium WebDriver is a more potent and improved version of the Selenium suite. WebDriver uses native browser techniques to establish direct communication with browsers.
• Selenium Grid: With Selenium Grid, quality assurance standards can run tests on numerous machines in parallel thanks to its intelligent proxy server. By acting as the hub and sending commands to distant web browser instances, this is accomplished.

Selenium is a comprehensive and effective solution for web automation testing, providing a range of testing objectives and scenarios thanks to its component-based approach.

Understanding browser testing with Selenium

Microsoft Edge Online helps users access the online application, and browser testing becomes a mission-critical approach. It entails ensuring that a web application is performing consistently across a variety of web browsers. Selenium is known for its robust automation features that serve as an indicator for testers looking to replicate user interactions and do rigorous browser testing, ensuring a consistent experience for all users.

It is impossible to exaggerate the significance of Selenium for browser testing. Browser incompatibilities can lead to a variety of problems, ranging from functional differences to layout inconsistencies. As a virtual testing assistant, Selenium helps the testers find and fix compatibility problems as early as possible so that the users have a flawless experience no matter which browser they choose.

How to perform browser testing using Selenium

Browser testing with Selenium requires a meticulous series of procedures to set up and execute tests efficiently. Begin by creating your Selenium setup and choosing the browsers on which the test is to be executed. This first setup is critical because it establishes the groundwork for a thorough testing procedure.

Once the setup is ready, Selenium provides an extensive array of functions and commands for interacting with web elements. Commands like sendKeys and findElement as a tool helps to simulate user interactions in Microsoft Edge online browsers. Adapting the test scripts to the particular oddities of the browser is essential to making sure the application runs constantly on all platforms.

Considering a feature-rich online web application that runs perfectly on Microsoft Edge online. But when users switch to Firefox or Safari, they encounter surprising differences in functionality and presentation. This is where Selenium’s browser testing powers step in to work as a protector, guaranteeing the dependability and user experience of your application on a variety of browsers.

Steps involved in browser testing with Selenium

As already mentioned, Selenium is the most widely used automated testing tool for a variety of features. One such feature that Selenium supports is browser testing, which may be carried out using the steps listed below:

• Identify the target browser and devices: The first step testers need to determine the browsers and devices they wish to test their web application on. This is dependent upon the demands of an organization, user demographics, and the market share of the devices and browsers. Using this information, they may rank the browsers and devices that are most crucial and can make a browser matrix that lists the various combinations of browsers, operating systems, versions, and devices that they wish to test.
• Setup the test environment: Setting up the test environment, where browser test cases will be executed, is the next step. Cloud-based test environment or a local test environment is used, depending on the preference. Installing and configuring the browsers, drivers, and Selenium web driver on a personal computer or a dedicated server is necessary for a local test environment. To access and execute the test cases on a remote server that supports a wide range of browsers and devices using a cloud-based test environment. Utilizing an AI-powered test orchestration and execution platform like LambdaTest to scale up testing, saving time and money, and interface with other technologies.
• Design the test cases: Creating test cases that cover the functionality and capabilities of the web application across the target browsers and devices is the third phase in the testing process. A framework like Page Object Model (POM) or Screenplay Pattern can be used to arrange structured and reusable test cases into logical and maintainable components. When creating the test cases, it is advised to give them meaningful and descriptive names, group and prioritize them using annotations or tags, verify expected results with assertions, validations, and checkpoints; parameterize them with varying inputs and outputs using data-driven testing; handle errors with exception handling and logging; and provide comments and documentation outlining their purpose and logic.
• Execute the test cases: Using Selenium Webdriver, running the test cases in the test environment is the fourth step. Test cases can be built and executed as a project. It’s crucial to use parallel testing to run your test cases concurrently across several devices and browsers while executing the cases. It is possible to manage and control browsers and drivers with the use of browser testing frameworks and tools like Selenium Grid. To identify and interact with the web elements, and the use of explicit and implicit waits to synchronize your test cases with the web components. Lastly, to emulate user interaction on the web elements, actions and events like click, type, scroll, drag, and drop should be used.
• Analyze the test results: The fifth step is to analyze the test results and identify any issues or defects that occurred during the test execution. Graphs, charts, images, and logs can be added to your test reports to improve and personalize them. It’s crucial to check the test findings for anomalies or disparities by comparing them on various browsers and devices. Along with determining the problem’s primary cause and level of severity, the problems into functional, compatibility, performance, and usability categories also need to be determined. Keep track of and record the problems and flaws together with any pertinent facts, like how to replicate the problem, the expected and actual results, browser and device information, and screenshots.
• Improve the test cases: The final step is to improve the test cases based on the feedback and learning from the previous steps. The test cases should be reviewed for redundancy, duplication, or complexity; they should be optimized and enhanced for increased coverage, efficiency, and reliability; they should be updated and maintained to reflect changes to the web application or target browsers/devices; and finally, they should be re-run and re-validated to make sure they function correctly on all target browsers/devices.

Best practices to accomplish browser testing in Selenium

The following are best practices that should be adhered to while performing browser testing using Selenium.

• Choose libraries and frameworks cautiously: Frameworks and libraries are necessary for web application testing. Before developing, remember that while the newest CSS frameworks can contribute to the most vibrant and dynamic user experience, they may not function with all browsers because each browser has a different rendering engine. Check the browser guidelines to see if they support the newest CSS libraries and frameworks before utilizing them.
• Use proper JavaScript libraries and task runners: Web app development heavily depends on JavaScript, therefore choosing the appropriate JavaScript resources that satisfy site specifications and provide suitable browser compatibility is important. There are numerous options available to task runners. They also enhance the overall application performance which in turn improves code quality.
• Carefully identify and analyze the browser operating system configuration: There are several versions of every browser, and some even undergo monthly updates. Therefore, to conduct browser testing using Selenium, it is vital to confirm which browser, browser versions, and operating systems are required. Give top priority to the combinations that the majority of the intended audience is most likely to utilize.
• Optimize Microsoft Edge Online: Microsoft Edge Online is not compatible with sophisticated CSS frameworks and styles. Many of a website’s design features are likely to be distorted, even if it is the ultimate in visual attractiveness.
