End-to-end tests are crucial components of modern CI/CD pipelines, helping to ensure that changes do not cause regressions before deployment. Playwright offers network inspection, automatic waiting, browser isolation, tracing and cross-browser execution. While useful for improving automation, these features cannot replace the engineering work needed to develop, identify and monitor effective tests.Requirements, source code, page structure, APIs, selectors, authentication rules, test data can all change at the same time in a sprint. The reason for a Playwright test failure can include any of the following: regression in the application, the application's outdated locator, outdated test data, inability to reach the application, or instability of the timing.
