Write strategic, focused tests for critical user flows and core functionality using modern testing frameworks, focusing on behavior over implementation. Use this skill when creating test files, writing unit tests, integration tests, or end-to-end tests in test directories (tests/, __tests__, spec/, *.test.js, *.spec.py). Apply this skill when testing core user workflows and business-critical features, implementing test-driven development (TDD) with red-green-refactor cycles, mocking external dependencies for isolated unit tests, using clear descriptive test names that explain expected behavior, following arrange-act-assert patterns, and ensuring tests run fast and independently. This skill prioritizes testing what matters most (primary user flows) while deferring edge cases and non-critical paths until later, emphasizes behavior testing over implementation details to reduce brittleness, and uses modern frameworks like Jest, Playwright, Cypress, pytest, RSpec, or Testing Library for reliable, maintainable test
