vitest-unit-testing

To prevent mock leakage in Vitest unit tests, you need to enforce strict mock cleanup after each test. This Skill automatically structures your .test.ts and .spec.ts files to guarantee mock hygiene and strong test isolation across your entire workflow.

The best way to structure Vitest unit tests is by using explicit Setup, Act, and Assert sections. This approach enforces clear testing boundaries and helps prevent false positives by ensuring robust isolation and explicit assertions in your test files.

You can reduce false positives in Vitest testing workflows by applying explicit assertions and robust isolation rules. This Skill guides you through writing, reviewing, and generating tests that mitigate false positives through strict structure and mock cleanup.

Yes, you can use this Skill to review existing .spec.ts and .test.ts files. It evaluates your current Vitest workflows against best practices, checking for explicit Setup/Act/Assert sections, mock cleanup, and false-positive mitigation.

Vitest test isolation requires specific setup to work reliably. This Skill enforces the necessary mock cleanup and structured test boundaries in your .test.ts and .spec.ts files to ensure each test runs independently without state leakage.
