vitest-react-ts-mocking
Implement mocking in Vitest for React-TS (modules, timers, fetch) and write tests that still achieve 100% coverage. Includes best-practice patterns to avoid brittle mocks.

Vitest Mocking (React-TS) + 100% coverage
You are adding mocks in Vitest while keeping tests robust and achieving 100% coverage.
Non-negotiables
- Tests remain deterministic and cover 100% of the code under test.
- Prefer mocking at the boundary:
- module boundary via vi.mock
- network boundary by stubbing fetch (or the project’s API client)
- Reset/restore mocks appropriately (clearMocks/mockReset/restoreMocks are enabled in config).
Use template.md as the default structure.
