[BUG] Empty cobertura.xml in coverlet.collector 6.0.3 that is not reproduced in 6.0.2 #1726
Description
Describe the bug
I recently upgraded to 6.0.3 and I noticed the pipelines failing. It seems that cobertura.xml comes out empty. I am using a runsettings file with exclude/include. I notice that if I remove these sections the cobertura gets populated.
That said, coverage works fine and cobertura gets entries on 6.0.2 of coverlet.collector nuget package.
To Reproduce
Check out https://github.com/kotsaris/repro-coverlet-empty-cobertura cd into ClassLibrary1 folder and run tests via
dotnet test --collect:"XPlat Code Coverage" --settings .\coverage.runsettingsExpected behavior
It should populate cobertura.xml with something.
Actual behavior
Cobertura.xml is empty.
