Provides guidance on Vitest mock patterns (vi.mock, vi.hoisted, vi.fn resets), TDD planning rules, and general test strategy to help developers write reliable tests with predictable behavior.
Apply Vitest mock patterns and TDD planning rules when writing tests.

Vitest mock patterns require vi.hoisted to manage hoisting behavior when using vi.mock, ensuring mocks are initialized before module imports. This approach provides predictable mock lifecycle management and stable test execution.
Vitest mock hoisting behavior often causes vi.mock failures when mock factories are not properly scoped. Implementing vi.hoisted ensures mock definitions resolve before module imports, preventing reference errors and unstable test patterns.
Type mock functions in TypeScript using vi.fn to preserve mock APIs and test ergonomics. Proper typing ensures deterministic test patterns and robust test design while maintaining full access to Vitest mock assertion methods.
TDD planning rules guide test organization by structuring scalable suites with clear guardrail decisions. Applying these patterns ensures deterministic test behavior and robust test design across complex JavaScript and TypeScript projects.
Reset vi.fn mocks between tests to maintain deterministic test patterns and prevent state leakage. Managing the mock lifecycle properly ensures predictable behavior and robust test design across your Vitest suite.
Yes, this guidance applies to developers writing or debugging tests in JavaScript and TypeScript projects using Vitest, covering clear mock typing, deterministic test patterns, and robust test design edge-case considerations.
