Testing for your React project
Expert testing for React applications. We find and fix React-specific bugs and performance issues that affect production apps. From $19.
React testing issues we find
Common testing problems specific to React applications.
Unnecessary re-renders
Missing React.memo, useMemo, and useCallback cause components to re-render on every parent update, degrading performance.
Unhandled promise rejections
Async operations in useEffect without proper error handling crash silently or show raw error messages.
Missing error boundaries
A single component error crashes the entire application. No fallback UI to gracefully handle failures.
Large bundle size
Importing entire libraries, unused dependencies, and no code splitting result in slow initial page loads.
Hydration mismatches
Server-rendered HTML doesn't match client-rendered output, causing layout shifts and console errors.
What our React testing covers
Unit tests
Tests for individual functions, utilities, and business logic. Catch bugs at the smallest level.
Component tests
Tests for React components — rendering, user interactions, state changes, and edge cases.
Integration tests
Tests for API endpoints, database operations, and multi-step workflows.
End-to-end tests
Full user flow tests that simulate real user behavior — signup, purchase, and critical paths.
Test infrastructure
Setting up Jest, Vitest, Playwright, or Cypress with proper configuration and CI integration.
CI/CD integration
Running tests automatically on every push so broken code never reaches production.
