Special Features of Playwright

Playwright also offers a set of advanced features that set it apart:

Resilience: Tests in Playwright are resilient to instability. The tool eliminates the need for artificial wait times, which are a major cause of unstable tests. Assertions are automatically retried until the necessary conditions are met, ensuring consistent results.

Tracing: Playwright allows for the configuration of retry strategies and captures execution traces, videos, and screenshots to eliminate instability issues, facilitating problem debugging.

No Limitations: Playwright leverages the modern architecture of browsers and runs tests outside the browser process, eliminating typical limitations of in-process test runners. This enables the execution of scenarios spanning multiple tabs, multiple origins, and multiple users in a single test.

Reliable events: Playwright employs a reliable event system that allows interaction with dynamic elements and the emulation of real user events.

Complete isolation: Each test in Playwright runs in an isolated browser context, ensuring complete separation and zero interference between tests. It also allows for the preservation of authentication state for reuse across all tests, avoiding repetitive login operations.

In summary, Playwright offers advanced features that ensure resilience, the elimination of unstable tests, the ability to execute complex scenarios, and a high degree of isolation, resulting in fast and efficient execution of E2E tests. These features make it a solid choice for projects requiring high-quality and reliable testing.
