Comprehensive patterns for writing maintainable, effective vitest tests. Focused on expert-level guidance for test organization, clarity, and performance.

This skill uses a progressive disclosure structure to minimize context usage:

Start with the Overview (AGENTS.md) Read AGENTS.md for a concise overview of all rules with one-line summaries and the workflow for discovering existing test configuration.

Use when writing, reviewing, or refactoring vitest tests. Load when you see *.test.ts or *.spec.ts files, nested describe blocks, loose assertions (toBeTruthy), over-mocking, slow tests, or async testing needs. Covers AAA pattern, parameterized tests, test doubles hierarchy, mock cleanup, test isolation, and performance optimization. Keywords include vitest, testing, TDD, assertions, mocks, stubs, fakes, spies, beforeEach, describe, it, expect, vi.mock, it.each. Source: gohypergiant/agent-skills.
