Why Test React Components?
Automated tests help ensure that a component continues to behave correctly after code changes.
Good component tests focus on behavior that matters to users rather than relying heavily on internal implementation details.
What Should You Test?
- Important content is visible.
- Buttons perform expected actions.
- Forms validate correctly.
- Loading and error states are displayed.
- Important user workflows work correctly.
Common Testing Tools
A common React testing setup uses a test runner such as Vitest together with Testing Library for rendering components and querying the UI.
