Implements high-performance testing strategies using Bun's native test runner and Jest-compatible APIs.
The Bun Testing skill empowers developers to leverage Bun's ultra-fast, built-in test infrastructure within the Claude Code environment. It provides comprehensive guidance on writing unit and integration tests using bun:test, managing complex mocks for both functions and modules, and performing snapshot testing. By enforcing best practices like proper setup/teardown hooks and avoiding external runner overhead, this skill ensures a streamlined, deterministic, and highly efficient testing workflow for modern TypeScript and JavaScript applications.
