System Documentation

What problem does it solve?

Flaky Vitest tests caused by lingering mock implementations across test boundaries, leading to false failures and brittle suites.

Core Features & Use Cases

  • Explicitly reset mock implementations between tests to prevent cross-test leakage.
  • Provide guidance for beforeEach patterns to re-setup full mocks after vi.clearAllMocks().
  • Handle scenarios where incomplete mocks cause TypeErrors by restoring a complete mock object.

Quick Start

Place a beforeEach in your test suite to reinitialize mocks with their full implementations.
