10 Best Practices For Selenium Automation Testing


Selenium is an open-source tool that is widely used for automating web browser testing. It provides a simple and effective way to simulate user actions on a web page and verify the expected results. Selenium allows testers to create automated tests in multiple programming languages such as Java, Python, C#, Ruby, etc.

Selenium WebDriver is the most commonly used API for browser automation. In order to achieve the desired results, testers need to follow certain best practices when using Selenium.

In this article, we will discuss ten best practices for Selenium automation testing that testers should follow.

Automation testing

Develop a Test Plan

Developing a test plan is crucial in Selenium automation testing as it serves as a roadmap for the testing process. It outlines the testing approach, scope, objectives, and the expected results. The test plan helps in ensuring that all the essential functionalities of the application are covered, and there are no gaps in the testing process.

Moreover, the test plan facilitates effective communication between the testing team and stakeholders by defining clear testing objectives and expectations. A well-designed test plan can also help in identifying potential risks and issues early in the testing cycle, allowing for timely corrective actions. Therefore, developing a comprehensive test plan is critical to the success of the Selenium automation testing process.

Use a Page Object Model (POM)

The Page Object Model (POM) is a design pattern used in Selenium automation testing that allows testers to separate the code that interacts with the web page from the test code. This makes it easier to manage the test code and ensure that any changes made to the web page do not affect the test code. Additionally, the POM improves the maintainability and readability of the test code.

LambdaTest plays a significant role in implementing the POM approach by providing a cloud-based testing platform that allows testers to run their Selenium tests on a wide range of browser and operating system configurations. By using LambdaTest in conjunction with POM, testers can improve their test coverage and reduce the time and effort required for testing.

Use Unique Identifiers

When writing Selenium scripts, it is important to use unique identifiers to locate elements on a web page. Using generic identifiers, such as class or tag name, can result in false positives or false negatives, which can cause tests to fail. Therefore, testers should use unique identifiers, such as ID, name, or CSS selector, to locate elements accurately.

Wait for Page Load

Selenium automation testing can be prone to timing issues due to the asynchronous nature of web pages. Therefore, testers should ensure that they wait for the page to load fully before interacting with it. This can be achieved using the implicit wait or explicit wait methods in Selenium. Additionally, testers should avoid using sleep statements as they are not reliable and can result in tests taking longer than necessary.

Use Descriptive Test Names

Using descriptive test names can help testers to quickly identify the purpose of each test. Additionally, it can make it easier to debug failing tests as the test name can provide valuable information about the test scenario. Testers should use descriptive test names that accurately describe the test scenario and expected outcome. Descriptive test names can provide information about the purpose, behavior, and expected outcome of a test, making it easier to identify the test’s functionality and purpose.

Cross browser testing

Use Cross Browser Testing

Cross Browser Testing is an important aspect of Selenium Automation Testing that ensures that the web application is compatible with multiple web browsers and their different versions. This helps to ensure that users have a consistent experience regardless of the browser they use. LambdaTest is a cloud-based platform that plays a crucial role in Cross Browser Testing by allowing developers and testers to test their web applications across 3000+ browser configurations, including Chrome, Firefox, Safari, Edge, and Internet Explorer.

Use Data-Driven Testing

Data-driven testing allows testers to execute the same test scenario with different sets of data. This can help to identify defects that may not be identified with a single set of data. Additionally, it can reduce the amount of time required to test different scenarios. Selenium supports data-driven testing using data providers or external files such as Excel or CSV files.

Use Assertions

Assertions are used to validate the expected outcome of a test scenario. Selenium supports assertions using the TestNG framework, which allows testers to assert that a certain condition is true or false. Additionally, assertions can be used to compare actual results with expected results, ensuring that the test scenario has been executed correctly.

Log Defects

The maintenance of log defects is a critical aspect of Selenium Automation Testing, as it allows developers and testers to keep track of errors and issues that occur during the testing process. Log defects can provide valuable insights into the root causes of issues, helping to streamline the debugging process and improve the overall quality of the web application.

Targeting Quick Feedback

Targeting quick feedback is essential in Selenium automation testing. It helps to detect issues early, improve the quality of the software product, and speed up the testing process. By following best practices like using automation tools, prioritizing test cases, using parallel testing, and implementing continuous integration, testers can ensure that they receive quick feedback on the success or failure of the test cases.


The article presents some useful best practices for Selenium Test Automation that can help improve the quality and efficiency of test automation efforts. By detecting bugs early in the development process, testers can ensure that the web application is reliable and user-friendly. It is also important to approach test design and strategy thoughtfully before writing Selenium test automation scripts. By doing so, testers can ensure that their test suites are comprehensive and effective in identifying issues. By following these best practices, testers can increase their productivity and deliver high-quality web applications.
