Testing and quality assurance ensure software works correctly before reaching users. Comprehensive testing strategies catch bugs early, saving time and protecting user experience.
Unit tests verify individual components work as expected. Integration tests check how components interact. End-to-end tests simulate real user scenarios to validate entire workflows.
Automated testing saves time on repetitive tasks and enables continuous integration. Test-driven development, where you write tests before code, improves design and catches issues early in the development process.
