OGC could provide a test-suite with public available OWS web services (WPS, WMS, ...) which can be used for OWS client tests (OWSLib, Birdy, Phoenix, ...):
- services could be provides as (docker) containers.
- could be hosted in the cloud.
- should be reliable.
- available for common protocols (WPS, WMS, WFS, WCS, ...) and versions (wps 1.0.0, wps 2.0.0).
- Services/Dockerfiles are versioned (public Git repo).
To make the service response more predictable the service URL should also have the version number of the service/container version, something like this:
