Playwright Tests Coupled to CSS Break Faster Than JavaScript Frameworks Release New Versions

Developers using end-to-end testing frameworks like Playwright are advised to avoid over-coupling their tests to user interface implementation details. Focusing on specific CSS selectors or XPath can lead to test failures when the frontend is refactored, even if the functionality remains unchanged. Instead, tests should focus on the feature being tested, using locators that mimic how a user interacts with the page. Playwright's API provides alternatives, such as role locators or test IDs, which are more resilient to changes in the DOM. Additionally, using reusable fixtures can speed up test execution and prevent repeated setup logic. By designing tests that focus on the user experience and avoiding redundant testing, developers can create more efficient and maintainable end-to-end tests, ultimately reducing costs and improving overall test effectiveness. This approach is crucial in ensuring the quality and reliability of software applications, particularly in industries where user experience is paramount.
