Quality assurance has transformed dramatically. At [BetterQA](https://betterqa.co/), we’ve spent 15+ years testing software for fintech, healthcare, and defense companies.

## Testing Types Quick Reference

**Unit Testing:** Individual functions in isolation. Cover 70-80% of codebase.

**Integration Testing:** Components working together. Test every API endpoint.

**E2E Testing:** Real user journeys. Use Playwright or Cypress.

**Regression Testing:** Ensure new changes don’t break existing functionality.

**Security Testing:** [Auditi](https://auditi.ro/) scans for GDPR, security, and accessibility issues.

## Test Design Techniques

**Equivalence Partitioning:** Divide inputs into groups that behave identically.

**Boundary Value Analysis:** Focus on edges where bugs hide.

**Decision Tables:** Handle complex business rules.

**State Transition:** Test system state changes.

## The Automation Pyramid 2026

Unit tests: 60-70%. Integration: 20-25%. E2E: 5-10%. AI-assisted: newest layer.

Record tests with [Flows](https://betterqa.co/flows-ai-automation-recorder/) – capture interactions, export to Playwright or Cypress.
