セキュリティとテスト

Implements comprehensive testing strategies for JavaScript and TypeScript applications using modern frameworks like Jest and Vitest.

This skill provides a structured approach to building robust JavaScript and TypeScript applications through standardized testing patterns. It offers ready-to-use configurations for Jest and Vitest, alongside detailed implementation guides for unit, integration, and end-to-end testing. By leveraging proven patterns for mocking dependencies, handling asynchronous operations, and applying Test-Driven Development (TDD) workflows, it helps developers maintain high code quality and prevent regressions in complex codebases.
