What problem does it solve?

Writing reliable unit tests is challenging when mocks leak, tests are poorly structured, and false positives slip through. This Skill enforces Vitest best practices to ensure mock cleanup, explicit Setup/Act/Assert sections, and strong test isolation.

Core Features & Use Cases

• Enforces a clear testing structure with Setup, Act, and Assert sections.
• Guarantees mock cleanup after each test to prevent leakage.
• Helps prevent false positives by explicit assertions and robust isolation rules.
• Suitable for creating, reviewing, or updating .test.ts and .spec.ts files across projects.

Quick Start

Run Vitest tests that follow the prescribed structure to validate unit logic immediately.
