Error in "describe Unknown Feature Type" test

[clausnagel]

The "describe Unknown Feature Type" test uses the following query to provide an unknown feature type for the DescribeFeatureType operation. It expects the WFS to respond with a HTTP status code 400.

?service=WFS&version=2.0.0&request=DescribeFeatureType&typenames=ns90:Unknown1.Type&namespaces=xmlns(xml,http://www.w3.org/XML/1998/namespace),xmlns(ns90,http://example.org),xmlns(wfs,http://www.opengis.net/wfs/2.0)

However, the query uses the typenames parameter which is not defined by the WFS specification. The parameter is called typename (without the trailing 's').

So, in my opinion, the WFS should ignore the unknown typenames parameter. And since the correct typename parameter is omitted, the complete application schema shall be returned (cf. chapter 9.2.4.1). And consequently, a HTTP status code of 200 must be send.

A correct WFS implementation will therefore fail this test.

Well, there is also another issue with this test IMHO.

The POST version runs fine because it uses the correct <wfs:TypeName> element. However, the test method describeUnknownFeatureType in the class DescribeFeatureTypeTests then checks for an InvalidParameterValue exception code. As references, cl. 8.3.4, 9.2.4.1 are listed on the method.

However, from these clauses I cannot read that an unknown feature type on a DescribeFeatureType operation shall raise an InvalidParameterValue. There is a similar requirement stated in ATS A.2.22.1.1 but this only refers to adhoc query expressions, not to DescribeFeatureType.

@clausnagel Thanks for reporting this.

typenames Parameter should be renamed to typename for DescribeFeatureType requests (I assume this also applies to other tests).

Specification/Test must be rechecked if InvalidParameterValue is the expected exception.

Fix is solved by PR #150.

For the question in #144 (comment) a new issue was created: #149

Fix was successfully tested with service provided by @clausnagel.
Test describe Unknown Feature Type is passing.
