Advanced Testing & Performance Validation
Overview
What
Contract testing, performance testing with gates, regression test automation, and runtime security testing (DAST).
Business Value
Catches performance regressions 100% of the time before production and reduces visual bugs by 90% through automated regression testing
DORA Impact
- Change Failure Rate
- Lead Time
Key Features

Capabilities in This Epic
Contract Testing Between Services
>= 70% of service-to-service integrations use contract tests (Pact) to prevent breaking changes.
Performance Testing in CI
>= 60% of critical APIs have automated performance tests with latency/throughput gates in CI pipeline.
Dynamic Application Security Testing
>= 70% of web apps scanned with DAST (OWASP ZAP, Burp) in staging environment weekly with findings tracked.
Mutation Testing for Critical Code
>= 50% of critical business logic code (payment, auth, data processing) uses mutation testing to validate test quality.
Visual Regression Testing
>= 60% of user-facing pages have automated visual regression tests (Percy, Chromatic) catching UI issues.

Mitigation: Set performance budgets (p95 < Xms). Fail builds on regression. Track performance trends over time.
Mitigation: Set pixel difference threshold. Ignore dynamic content (ads, timestamps). Review baseline images regularly.
Mitigation: Run mutation tests on changed files only. Run full suite nightly. Focus on critical paths first.
Next Steps
After Completing This Epic
Once you've met all exit criteria, consider these next steps:
- Review metrics to validate DORA improvements
