概要
Provides comprehensive guidance for testing TypeScript and JavaScript code within a Bun-based project. It utilizes Bun's built-in test runner and champions a strict "no mocks" integration testing philosophy, focusing on testing observable behaviors with real objects and data. Use this skill when you need to write new tests, debug existing ones, or understand the project's specific testing conventions and best practices. It includes commands for running tests, templates for structuring new test files, and clear examples for creating reliable and maintainable tests.
