Testing
Test configuration#
The repo's test setup lives in test.config.ts at the project root, alongside vite.config.ts. Since Vitest is Vite-native, the test runner shares the same underlying tooling as the library's build step described in local development.
Why this pairing#
- Vitest gives fast, Vite-powered test runs with the same module resolution and config as the rest of the build.
- React Testing Library encourages testing components the way a user would interact with them — through rendered output, not internal implementation details.
Where testing fits in#
Tests run alongside the other quality tooling in the repo: ESLint for static analysis, Husky git hooks to catch issues before a commit lands, and Chromatic for visual regression testing against the Storybook catalog. See tech stack for how all of these fit together.
