1. Advanced Techniques For Using Selenium

Selenium is a widely used tool for web application testing. It authorizes testers to write scripts in various programming languages, such as Java, Python, and C#, to simulate user interactions with web applications. However, mastering Selenium requires much more than just writing basic scripts. Advanced techniques can help testers to create more effective and efficient test cases and to troubleshoot complex issues that may arise during testing. Here are some of the advanced techniques for using Selenium.

a. Use BDD Framework

Behavior Driven Development (BDD) has emerged as a widely accepted development approach for Selenium test automation. BDD enables testers to write Selenium test cases in plain English without requiring coding knowledge. This approach facilitates better communication and collaboration between the organization and technical teams, providing a clear understanding of the project’s progress. Ultimately, BDD promotes a more efficient and effective development process.

Using BDD to write your Selenium test automation scripts can enhance the team’s understanding of test specifications and requirements, ultimately saving time by reducing the need for additional explanations. With a better understanding of the tests, the business team may provide valuable input based on business benefits.

b. Optimizing Web Development with a Browser Compatibility Matrix

Conducting cross-browser testing can present a significant challenge, as it requires prioritizing testing on various browser and operating system combinations. The number of combinations quickly becomes extensive when accounting for the numerous browser versions available. Establishing a formal list of (browser + OS + device) combinations is essential to prioritize which combinations should be tested for cross-browser compatibility. This formalized list is commonly called a Browser Matrix or Browser Compatibility Matrix.

Browser Matrix is a crucial tool that provides valuable insights based on product analytics, geolocation data, and audience usage patterns. This information includes statistics such as counters and competitor analysis. By utilizing Browser Matrix, you can ensure that your product covers all the essential browsers while reducing the time and resources necessary for development and testing.

c. Use Selenium Wait Commands

Web page load times can vary depending on network conditions, server issues, or system configurations. To address this issue, quality assurance (QA) professionals might use the Thread.sleep() method to pause the automation script for a long time.

However, this approach is not ideal because it may result in inefficient testing. A website may take longer than the predetermined time or load faster, causing slower test execution. Instead, a more efficient alternative is to use Implicit or Explicit Wait Commands in Selenium. This method allows for better synchronization between the script and the webpage, improving test accuracy and efficiency.

d. Set Up Selenium Test Automation Reports

“You can’t improve what you can’t measure.”

This phrase stands true in the case of Selenium test automation as well. Keeping track of test performance is paramount to ensure better results in Selenium test automation. Generating automation testing reports aids in improving the readability of test results and minimizes the time and effort spent on maintaining test data.

Selenium test automation report generation can be a game-changer as it saves precious time and assists in managing test data in an organized manner. This, in turn, provides better control over tests and enables analysis of test script failures using the collected data.

e. Take Automated Screenshots For Test Failures

It is common for Selenium scripts to encounter failures during testing. One of the challenges faced during such instances is determining the root cause of the problem, whether due to an issue in the test code or a bug in the application under test (AUT).

To address this challenge, it is recommended to establish a test infrastructure that automatically captures screenshots whenever a test failure occurs. This approach can significantly simplify investigating and identifying issues, reducing the time and resources required for analysis. Ultimately, implementing a robust test infrastructure that includes automated screenshot capture can enhance the effectiveness and efficiency of the testing process.

f. Planning and Designing Test Cases Beforehand

Before initiating test automation, it is recommended to follow the best practice of creating scenarios and test cases beforehand. Directly proceeding with automation devoid of a well-structured test design can pose potential risks. Therefore, to ensure the success of Selenium test automation, it is imperative to have a test design coupled with a strategic plan. Establishing a test architecture that outlines the test program structure and how it will be managed is crucial.

Automation without proper design focuses only on script functionality, disregarding the potential scenarios that may arise during testing. It is essential to consider various scenarios for comprehensive testing. Minimizing the test scope solely to ensure script execution is not advisable. Through Selenium test automation, testers can develop scripts using several programming languages.

g. Running Selenium Tests on Real Devices

While several emulators can be used for Selenium testing across platforms, testing on actual devices provides a significant advantage. Emulators are software programs that simulate device functionality and are more appropriate for testing code changes during early development. Finding emulators for specific device-OS combinations can be difficult, presenting challenges for quality assurance teams.

Testing websites under real user conditions is crucial to achieving precise and reliable results. This allows teams to identify and address a maximum number of bugs, resulting in the release of a more robust application.

Running Selenium tests on digital experience testing platform like LambdaTest is a great way to ensure that your web application works seamlessly across different devices and platforms. It allows users to test their websites and web applications on a wide range of real browsers, operating systems, and mobile devices without having to set up their testing infrastructure.

h. Not Completely Relying On An Automation Tool

Automation tools are crucial in various testing activities, including automated browser testing. However, it is vital to note that they do not provide a complete solution. Selecting appropriate tools is critical to transitioning to an automated browser testing framework. However, it is just the initial step!

Unfortunately, some developers mistakenly believe that choosing the right tool will enable them to automate everything. However, no tool can offer a comprehensive solution. While they simplify the process, skilled resources are necessary to conduct testing effectively.

Automation tools may have difficulty identifying intricate objects within software or applications when utilized without human intervention. However, with the assistance of knowledgeable personnel, these obstacles can be overcome and leveraged for the betterment of the organization.

i. Use the Page Object Model

As a web application’s user interface (UI) evolves, the associated locators change, requiring the need to rewrite all tests. However, the Page Object Model (POM) presents a viable solution to this problem. By using POM, one can avoid modifying test scripts repeatedly.

POM offers a centralized repository of all locators, thus necessitating only the modification of page objects. Each webpage in POM has a separate page class that identifies web elements and associated page methods. This approach enhances project reliability, as developers do not need to scan through the entire code and test scripts to incorporate minor UI changes.

j. Avoid Code Duplication

An effective approach for successful Selenium test automation is to minimize code duplication. Utilizing various web locators like XPath and ID for accessing web elements can result in repetitive code. To address this issue, frequently used code segments should be created as a separate API to minimize repetition.

Not only does this approach reduce the amount of code, but it also enhances the test code’s maintainability. Wrapping Selenium calls is another best practice that can considerably impact maintaining a complex test suite or test code.

2. Conclusion

Advanced Selenium techniques provide powerful tools for web developers and testers to build more reliable and robust web applications. By utilizing the above-stated advanced techniques, developers can speed up their testing process and catch issues earlier in the development cycle. These advanced techniques are essential for keeping pace with the demands of modern web development, and mastering them will enable developers to create more resilient and efficient web applications.
