Testing Strategy & Quality Gates
Overview
What
Comprehensive testing strategy with unit, integration, contract, and E2E tests. Test pyramid, coverage enforcement, and quality gates in CI.
Business Value
Catches 70% of bugs before production deployment and reduces QA cycle time by 50% through comprehensive automated test coverage
DORA Impact

When
Foundation (0-90 days)
Capabilities in This Epic
Code Coverage Baseline
>= 70% code coverage for unit tests with branch coverage tracked and enforced in CI.
Integration Testing
>= 60% of services have integration tests covering critical API endpoints and database interactions.
End-to-End Testing
>= 50% of critical user journeys covered by automated E2E tests (Playwright, Cypress).
Test Data Management
>= 70% of tests use factories or builders for test data (no hardcoded magic values).
Flaky Test Detection
>= 90% of flaky tests detected and fixed within 1 sprint. Flaky rate < 2%.
Parallel Test Execution
>= 70% of test suites run tests in parallel, reducing total test time by >= 50%.

Mitigation: Track branch coverage, not just line coverage. Review coverage reports in PRs. Require assertions in tests.
Mitigation: Containerize dependencies (Docker Compose). Use test fixtures or factories. Reset state between tests automatically.
Mitigation: Create dedicated test environment. Use synthetic test data. Isolate test runs with unique identifiers.
Next Steps
After Completing This Epic
Once you've met all exit criteria, consider these next steps:
- Review metrics to validate DORA improvements
