# React Testing Rules

- Test user-visible behavior, not component internals.
- Prefer role, label and text queries that mirror accessibility semantics.
- Avoid brittle snapshots unless they protect a deliberate rendering contract.
- Use realistic interaction flows and assert loading, error and empty states.
- Keep mocks narrow and local; do not mock the component under test.
- Add regression tests for bug fixes touching shared components or workflow logic.

它会指定测试运行器吗？

不会。它适用于 Vitest、Jest 或仓库已经采用的测试运行器。

为什么强调 role 查询？

role 查询更接近用户和辅助技术看到的界面，能让测试更稳定，也能反馈可访问性问题。
