fix CoverletOutput folder location #1601

Bertk commented 9 months ago

Filename for multiple report formats is currently not supported. CoverletOutput parameter without file shall be used instead e.g. /p:CoverletOutput="C:/GitHub/coverlet/artifacts/Reports/coverlet.core/"

I've seen that we have the same issue for coverlet.console. The idea to just use the output directory in those cases sounds good to me. We can also create a new issue for this.

Update of GlobalTool.md should be sufficient e.g.

whenever more than one coverage format is used in combination with output parameter only a folder shall be used

current paragraph

The above command will write the results to the supplied path, if no file extension is specified it'll use the standard extension of the selected output format. To specify a directory instead, simply append a / to the end of the value.

coverlet <ASSEMBLY> --target <TARGET> --targetargs <TARGETARGS> --output "/custom/directory/" -f json -f lcov
