Validate OpenAPI before every release
Catch broken contracts early—missing paths, info blocks, or version drift.
OpenAPIAPICI
Key takeaways
- Structural validation is not a substitute for response schema tests—but it blocks obvious ship-stoppers.
- Keep one canonical spec file per service; validate the same artifact you publish.
Why validate in CI
Broken specs break codegen, documentation portals, and API gateways in cascading failures.
A quick structural pass saves hours when a missing paths object ships to production docs.
Workflow
Paste JSON or YAML into OpenAPI Validator after merging feature branches.
If valid, spot-check critical paths with HTTP Request using the same base URL and auth.
FAQ
Does this validate response examples?
It checks top-level contract shape; add contract tests for payload examples and status codes.
Swagger 2.0 support?
Basic structural checks apply; migrate to OpenAPI 3 when possible for richer tooling.
