# QA Fundamentals

Testing Pyramid

Unit tests at the base (most), integration in the middle, E2E at the top (fewest). More unit tests means faster feedback and lower cost per run.

Manual vs Automated

Manual testing for exploratory and UX review. Automated for regression and CI pipelines.

Common Test Types

Smoke test confirms a deploy is functional. Regression test confirms existing features still work. Acceptance test verifies business requirements. Performance test measures throughput and response times.
