Ensure templated source tests aren't collected unconditionally

Phil Dawsonrequested to merge
phil/fixup-templated-test-collection into master

Description

Currently, when attempting to run a subset of the test suite, the templated source tests in buildstream.testing._sourcetests will be collected, regardless of whether they are desired or not (see #995 (closed))

Changes proposed in this merge request:

  • Add some logic to testing.sourcetests_collection_hook to decide if templated tests should be collected based on the arguments provided to pytest.

This merge request, when approved, will close: #995 (closed)
