testing-mastery

To improve code quality, this Skill orchestrates a comprehensive testing strategy encompassing TDD, unit testing, and integration testing. It guides developers through the Red-Green-Refactor cycle and offers patterns for testing individual components and their interactions to catch regressions early.

The best way to set up E2E testing with Playwright is by simulating critical user journeys like checkout. This Skill provides specific strategies and runtime scripts for executing Playwright tests to validate business logic and ensure a seamless user experience end-to-end.

Yes, the testing strategy includes runtime scripts designed for test execution and accessibility checks. These scripts enable immediate execution of the unified test runner for the current project while enabling coverage reporting to validate critical user flows.

You need integration testing when validating interactions between individual components, while E2E testing is needed for validating critical user flows. The Skill guides the selection of appropriate testing methods based on whether you are fixing bugs, developing features, or validating business logic.

Yes, you can use this Skill to guide the TDD workflow for a new authentication module. It directs the process of writing tests first, implementing the code, and finally refactoring for clarity and efficiency, ensuring development confidence and catching regressions early.
