Use Automated Test Selection Methods
Automated test selection approaches are a beneficial tool for streamlining the regression testing process. It ensures that the most crucial test cases are executed swiftly and efficiently. The machine learning algorithm is one such method utilized to pinpoint the most frequently failing test cases in previous test runs.
By prioritizing these failing tests, teams can concentrate on the areas of the application that are most likely to have issues. It also diminishes the overall time and endeavor required for regression testing. Another approach is to utilize code coverage analysis.
Code coverage analysis assists in identifying the areas of the application that have undergone the most changes since the last test run. It assures that the most relevant test cases are executed first. This provides teams with the ability to swiftly identify any regressions that may have emerged. Overall, incorporating automated test selection methods into your regression testing strategy can help increase test coverage and accuracy while diminishing the time and effort required for testing.
Continuously Update the Test Suite
One of the most crucial strategies for selecting the suited regression test cases with Playwright is continuously updating the test suite. As applications evolve and change, so should the tests used to verify their functionality. Updating the test suite ensures that the test cases remain relevant and effective in catching any potential regressions. It also helps to eliminate any redundant or obsolete test cases that are no longer necessary.
Teams can guarantee that they are testing the most crucial areas of the application by regularly reviewing and updating the test suite. Regular reviewing can also guarantee that their tests are furnishing the most value. Updating the test suite facilitates maintaining the efficiency and effectiveness of the test automation process. This authorizes teams to catch any issues early and reduce the risk of introducing new defects into the application.
Bonus Tip: Use a Risk-Based Testing Approach
A risk-based testing approach implicates pinpointing the areas of the application that are most presumably to fail or have the highest impact on the end-user experience. By focusing on these high-risk areas, you can prioritize test cases that have the highest potential for finding regression defects. This approach is particularly useful when there are time constraints or limited resources for testing.
Playwright furnishes features such as page and element selectors that can be used to target explicit areas of the application, making it easier to identify high-risk areas and prioritize relevant test cases. A risk-based approach can assist you in identifying test cases that can be skipped, such as those that cover low-risk or seldom-used features. By skipping these test cases, you can save time and resources while ensuring that the most critical areas of the application are thoroughly tested.
The Playwright’s ability to run tests in parallel can assist in speeding up the process.
