<default_to_action> When designing or improving test automation:
Quick Anti-Pattern Detection:
Critical Success Factors:
| Layer | % | Speed | Isolation | Examples |
|---|---|---|---|---|
| Unit | 70% | < 1ms | Complete | Pure functions, logic |
| Integration | 20% | < 1s | Partial | API, database |
| E2E | 10% | < 30s | None | User journeys |
| Principle | Meaning | How |
|---|---|---|
| Fast | Quick execution | Mock external deps |
| Isolated | No shared state | Fresh fixtures per test |
| Repeatable | Same result every time | No random data |
| Self-validating | Clear pass/fail | Assert, don't print |
| Timely | Written with code | TDD, not after |
| Problem | Symptom | Fix |
|---|---|---|
| Ice cream cone | 80% E2E, 10% unit | Invert pyramid |
| Slow suite | 30+ min CI | Parallelize, prune |
| Flaky tests | Random failures | Quarantine, fix timing |
| Coupled tests | Order-dependent | Isolate data |
| Brittle selectors | Break on CSS change | Use data-testid |

Pyramid: 70% unit, 20% integration, 10% E2E. F.I.R.S.T. principles for every test. Page Object Model for E2E. Parallelize for speed. Quarantine flaky tests - never ignore them. Treat test code like production code.
With Agents: Agents generate pyramid-compliant tests, detect flaky patterns, optimize execution time, and maintain test infrastructure. Use agents to scale automation quality.
