unit-testing

To write reliable Vitest unit tests, use the standard arrange-act-assert template, apply typed mocks for dependencies, and follow lint-friendly conventions to test React components, hooks, and utilities consistently across your repository.

Structure reusable test utilities by extracting setup logic into helper modules, adhering to repository-wide testing conventions to reduce boilerplate, prevent common mocking pitfalls, and maintain consistency across multiple test files.

Create typed mocks for React hooks by leveraging Vitest's typing helpers within the testing template, ensuring that mock implementations match your interface signatures to guarantee type safety and lint compliance.

The Vitest testing template encodes specific lint-friendly conventions and setup patterns, ensuring that your unit tests for utilities and React components pass linting checks without requiring additional configuration.

You can use the template for testing plain utility functions alongside React components and hooks, providing a standardized arrange-act-assert structure and mocking guidance that applies broadly across repository-wide unit tests.
