Component Testing Pattern

Test React components with React Testing Library using user-centric queries, event simulation, context providers, and hook testing.

What's Included#

  • Basic component rendering tests with role-based queries and variant testing
  • User interaction testing with userEvent for realistic click, type, and keyboard events
  • Async component testing with MSW for mocked API responses
  • Context provider wrapper utilities for theme, auth, and multi-provider testing
  • Custom hook testing with renderHook, act, and fake timers

Via AI Assistant#

Ask your AI assistant:

  • "Use the component testing pattern from Bootspring"
  • "Apply the Bootspring component testing pattern to my project"

Key Considerations#

  • Test from the user perspective focusing on what users see and do, not internal state
  • Prefer accessible queries (getByRole, getByLabelText) over implementation-dependent selectors
  • Use userEvent over fireEvent for more realistic user interaction simulation
  • Test all UI states including loading, error, empty, and success scenarios
  • Use screen queries instead of destructuring render results for cleaner test code
