Selenium testing enables cross-browser compatibility which means web applications can be run across multiple browsers and platforms. Being an open-source framework, Selenium can also be opted for by developers and teams that want less expenses without hampering high-quality standards.
It also allows developers to write test scripts in different programming languages including Python, Java, etc which allows reusable and maintainable code. It allows parallel execution of test scripts which can remarkably reduce the execution time for the tests.
Selenium’s seamless integration with CI tools like Travis CI, Jenkins, and CircleCI allows for automated test execution as part of the CI/CD pipeline. It also enhances the scalability of the testing process as tests can be executed across different machines and environments.
A bug-free test result is also promoted by Selenium. It also executes test scripts in a precise manner which maximizes its reliability and accuracy. It also leverages the testing result as it gives developers to choose the programming language in which they are compatible.
Tips for Effective Selenium Testing
A well-planned and calculated approach is very crucial for achieving effective Selenium testing results. By practicing some tips developers can ensure efficient, and reliable automation efforts for their tests that are easily maintainable too. Some tips that can help one boost the effectiveness of their Selenium testing are mentioned below
Planning test strategy
The first and foremost tip before diving into test automation in Selenium is that one needs to precisely plan the test strategy. That can be many for example classifying the test cases based on their criticality, recognizing the scope of testing, and illustrating fair objectives for the success of each test suite.
Page Object Model (POM)
POM which can be abbreviated as the Page Object Model can be implemented to escalate the readability and maintainability of the tests.POM is a universally accepted and used design pattern in the automation testing suite of Selenium. POM comes with important benefits ranging from fostering and improving the reusability of the code to minimizing the duplication of the code and amplifying the test maintainability.
With the help of POM better code organization can be promoted and the code can be read in an easier and more structured way as it separates the test cases from the details of the UI elements.
CI tools integration
Integrating Selenium tests with CI tools like Travis CI, Jenkins, and CircleCI, enables developers to automate test execution as part of the CI/CD pipeline. CI or Continuous Integration is a software development method that can build and automate an integrated code.
The CI tool plays a vital role in the realm of Selenium Automation Testing. This tool can ensure a smooth running testing process and can also detect the problems that arise at the beginning of the development cycle, ensuring a good and efficient quality application and continuous feedback throughout the cycle
CSS selectors
CSS selectors are often used to locate and interact with web page elements in the Selenium automation testing framework. Using CSS selectors in Selenium can offer various benefits providing a flexible and powerful way with which one can identify and select elements as per their features and traits.
CSS selectors in Selenium also allow developers to pick out specific elements on a web page in a very convenient way by specifying the element’s CSS selector in your code with the help of links, buttons, dropdown menus, or text boxes.
Cross-Browser and Cross-Platform Testing
Running tests across multiple browsers and platforms allows developers to ensure application compatibility and also implement cross-browser and cross-platform testing. It is important that one performs Selenium tests on popular web browsers like Firefox, Safari, Chrome, and Edge and also runs on different operating systems so that no platform-specific and browser-specific issues arise later on.
