End-to-end (E2E) regression testing is a type of software testing that verifies the functionality of an entire software system, from start to finish. It is typically performed after changes have been made to the system to ensure that these changes have not introduced any new bugs or broken existing functionality.
E2E regression testing can be performed manually or automatically. Manual E2E testing involves a tester executing a series of test cases that simulate the real-world use of the software system. Automated E2E testing uses software tools to execute the test cases automatically. Why is E2E Regression Testing Important?E2E regression testing is important because it helps to ensure the quality and reliability of software systems. By testing the entire system from start to finish, E2E regression testing can help to identify bugs that may not be caught by other types of testing, such as unit testing and integration testing. E2E regression testing is also important because it can help to reduce the risk of releasing software systems that contain bugs. By performing E2E regression testing before a new release, software teams can identify and fix any bugs before they are seen by customers. How to Perform E2E Regression Testing To perform E2E regression testing, you will need to: Identify the most important areas of the software system to test. This may involve performing a risk assessment to identify the areas of the system that are most likely to be affected by changes. Create test cases that cover the most important areas of the system. Test cases should be clear, concise, and easy to follow. Execute the test cases manually or automatically. If you are executing the test cases manually, be sure to document your results thoroughly. Analyze the results of the test cases to identify any bugs. If any bugs are found, report them to the development team so they can be fixed. Best Practices for E2E Regression Testing Here are some best practices for E2E regression testing: Use a risk-based approach. Focus your testing efforts on the most important areas of the system and the areas that are most likely to be affected by changes. Automate as much as possible. Automating E2E tests can help to reduce the time and cost of testing. However, it is important to note that automation is not a silver bullet, and some aspects of E2E testing may need to be executed manually. Use a variety of testing tools and techniques. There are a number of different testing tools and techniques that can be used for E2E regression testing. It is important to use a combination of tools and techniques to ensure that the system is tested thoroughly. Document your tests and results thoroughly. This will help you to track your progress and identify any trends in the number of bugs found. Challenges of E2E Regression Testing E2E regression testing can be challenging for a number of reasons, such as: Complexity: E2E regression tests can be complex to develop and execute, especially for large and complex software systems. Time and cost: E2E regression testing can be time-consuming and expensive to perform, especially if it is done manually. Frequency of changes: Software systems are constantly being changed, so E2E regression testing needs to be performed frequently to ensure that the system is still working correctly.

It helps to ensure the quality and reliability of software systems by testing the entire system from start to finish. While E2E regression testing can be challenging, there are a number of things that can be done to make it more efficient and effective, such as using a risk-based approach, automating as much as possible, and using a variety of testing tools and techniques.
