A production API defect should surprise you only once.
Every production bug reveals an assumption that was not tested. After fixing it, reproduce the original request, verify the correction, and turn the scenario into a reusable API regression test.
This is especially important for:
- API authorization failures
- Input validation bugs
- HTTP protocol errors
- API performance issues
- Pagination problems
- Security vulnerabilities
- Data integrity failures
- Third-party integration defects A code fix solves the problem today. A reusable API test helps prevent the same defect from returning in a future release.
The goal of API testing is not only to find and fix bugs. It is also to preserve what the team learned and continuously expand the system’s regression coverage.
This is the tenth rule in The Power of Ten Rules for Testing HTTP APIs.
