Write minimal strategic tests during development focusing on core user flows and critical paths, deferring comprehensive edge case testing until after feature completion. Use this skill when writing tests for completed features, testing critical user workflows, implementing integration tests, creating end-to-end tests with Playwright, writing unit tests for core logic, or determining testing strategy and priorities. Apply when working on test files (*.test.ts, *.spec.ts, *.test.tsx), Playwright test files (e2e/*.spec.ts), test configuration, or when deciding what to test during feature development. This skill ensures minimal tests during active development (complete the feature first), focus exclusively on core user flows and critical paths (skip non-critical utilities), deferred edge case and validation testing until dedicated testing phases, behavior testing over implementation details (test WHAT not HOW), descriptive test names that explain the behavior and expected outcome, mocked external dependencies (d
