ERROR: There was an error during testing

The warning should be detected, since @test_nowarn fails for the same function call. The example test from the documentation works, so I wonder if it has to do with add_label_column! being inside a package module.

I've tried using :Warn instead of :warn, as well as changing the warning to an @info message, like in the example.

As a workaround, I am using match_mode=:any, since I can't find any way to match patterns if the test is being called from withing PreprocessMD.
