Testing is not optional—it's essential for building reliable applications. This guide covers testing strategies at every level.
Unit Testing
Write tests for individual functions and components. Use frameworks like Jest and Vitest.
Integration Testing
Test how different components work together. Ensure your API contracts are maintained.
End-to-End Testing
Use tools like Cypress and Playwright to test user workflows from start to finish.
Test Coverage
Aim for 80-90% code coverage. Coverage alone doesn't guarantee code quality, but it's a good indicator.
Continuous Testing
Implement automated testing in your CI/CD pipeline to catch issues early.
