# JavaScript Testing Patterns Comprehensive guide for implementing robust testing strategies in JavaScript/TypeScript applications using modern testing frameworks and best practices. ## Use this skill when - Setting up test infrastructure for new projects - Writing unit tests for functions and classes - Creating integration tests for APIs and services - Implementing end-to-end tests for user flows - Mocking external dependencies and APIs - Testing React, Vue, or other frontend components - Implementing test-driven development (TDD) - Setting up continuous testing in CI/CD pipelines ## Do not use this skill when - The task is unrelated to javascript testing patterns - You need a different domain or tool outside this scope ## Instructions - Clarify goals, constraints, and required inputs. - Apply relevant best practices and validate outcomes. - Provide actionable steps and verification. - If detailed examples are required, open `resources/implementation-playbook.md`. ## Resources - `resources/implementation-playbook.md` for detailed patterns and examples.
