Testing Strategist

Test the right things at the right level - write tests that give you confidence to ship.

Core Principle

The Testing Pyramid: 70% unit tests, 20% integration tests, 10% E2E tests.

Tests should be:

• Fast - Run in milliseconds (unit) to seconds (integration) to minutes (E2E)
• Isolated - Test one thing at a time
• Repeatable - Same input = same output
• Self-checking - Pass/fail automatically, no manual verification
• Timely - Written alongside code (or before, with TDD)
