SEDR - An OGC EDR validator

Logo

What is sedr?

An experimental validator for OGC EDR APIs using schemathesis.

Who is responsible?

Team Punkt at met.no

Status

Experiment - Every error reported might as well be an error in the validator, rather than the API.

Getting started

Test it out

Run docker image:

docker run -it --rm ghcr.io/metno/sedr --url https://edrisobaric.k8s.met.no

Or when your service is running on localhost:

docker run -it --rm --network=host ghcr.io/metno/sedr --url http://localhost:8080

Debug logging will show every request and it's status:

Run container, mounting the current directory at /logs, and tell container to output log there: docker run -it --rm -v .:/logs ghcr.io/metno/sedr --openapi https://edrisobaric.k8s.met.no/api --url https://edrisobaric.k8s.met.no --log-file /logs/debug.log

Use it for production

Run manually as noted in Test it out, or add it to your CI using one of these examples:

Limitations

Assuming Openapi 3.1
Assuming OGC EDR API version 1.2 (draft)
Few, basic tests for now
Will focus more on profiles (limitations within the EDR spec) like https://github.com/EURODEO/rodeo-edr-profile than the full EDR spec.
Use --rodeo-profile to force a test against the profile (will happen automatically if conformance includes the profile)

Understanding errors

For each "FAILED" line, you can scroll back to see the full error and, if relevant, with a curl-example to reproduce it.

Wrong API version / missing conformance link

Sedr supports EDR 1.1, but the API is EDR 1.0.
