[MapServer-dev] Testing WMS with Teamengine

I first run the test but now I have also read part of the documentation. There may be other errors if the test server is configured properly. For getting a certificate it is mandatory to set up a service that contains layers from the shapefiles of the standard dataset https://cite.opengeospatial.org/teamengine/about/wms13/1.3.0/site/

The first step could be to add a new demo service "WMS CITE service" into https://demo.mapserver.org/. And I think that the CITE mapfile should be maintained somewhere in GitHub https://github.com/MapServer/MapServer. Maybe a copy of CITE vectors could be there as well because it is a very small dataset. Unfortunately there in not any kind of license file included in the zipfile that I just downloaded. That way it should be rather easy to run CITE tests also with locally installed Teamengine, maybe even automatically and integrated with CI process. Some public online service is needed anyway for the certificate and demo.mapserver.org feels good for that purpose. The one who maintains the service may disagree, though.

Are they the only 2 issues to meet compliancy for WMS 1.3.0?
The first seems an easy fix - simply changing the error code (I presume the message is ok?).

No idea for the second though. image/vnd.jpeg-png is supported by GeoServer and MapProxy which I presume work the same way? Seems more like an issue for OGC, but as you write  it may be easiest to remove the format from the test server.

I tested if MapServer could get an OGC WMS 1.3.0 certificate. At least one failure seems relevant. I used https://demo.mapserver.org/cgi-bin/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities for testing and this GetFeatureInfo test fails: Assertion: When GetFeatureInfo is requested on a Layer that is not queryable, then the server issues a Service Exception (code=LayerNotQueryable).

Mapserver gives this error instead: msWMSFeatureInfo(): WMS server error. Layer(s) specified in QUERY_LAYERS parameter is not offered by the service instance.

Test query: https://demo.mapserver.org/cgi-bin/wms?FoRmAt=image%2Fpng&InFo_fOrMaT=text%2Fhtml&CrS=EPSG%3A4326&I=50&HeIgHt=100&J=50&ReQuEsT=GetFeatureInfo&StYlEs=&QuErY_LaYeRs=bluemarble&VeRsIoN=1.3.0&LaYeRs=bluemarble&BbOx=-90.000000,-180.000000,90.000000,180.000000&WiDtH=100

Another failure comes from the MIME type test but I do not know how and where to resolve it. The test is "For format "image/vnd.jpeg-png", when the FORMAT parameter is set to that format, the MIME type of the response matches that format". That will fail because the jpeg-png is sort of a bogus mime type and the result is either jpeg or png. Maybe the format should be disabled from the service that is used for OGC tests. Of course if OGC recognizes image/vnd.jpeg-png then the Teamengine could be made to accept jpeg and png.

I found also some issues in the Teamengine that created odd looking requests which yielded errors from Mapserver. I will contact the Teamengine developers for resolving which part has a bug.
