coverlet always runs dll in debug folder

[TerryChan2]

I have a test.dll in bin\Release folder but the bin\Debug folder is empty under a project folder. When I run coverlet as shown below

1. Go to project folder => cd C:\projects\project.tests
2. Run coverlet => coverlet .\bin\Release\test.dll --target "dotnet" --targetargs "test C:\projects\project.tests --no-build" --format cobertura

The output shows below:
BadImageFormatException during MetadataReaderProvider.FromPortablePdbStream in InstrumentationHelper.PortablePdbHasLocalSource, unable to check if module has got local source.

If I copied the files from Release folder to Debug folder, the test cases can be executed as shown below:

How to config coverlet to run the dll in release folder?

[petli]

You have to tell dotnet test to run the release configuration:

coverlet .\bin\Release\test.dll --target "dotnet" --targetargs "test C:\projects\project.tests --no-build -c Release" --format cobertura

Thanks petli. It works!

I have another test2.dll and run the coverlet for that dll would produce below:

Is this issue related to #775 ?

[petli]

I can't say if it has anything to do with that issue. Maybe it is that the project uses .NET Framework 4.5.2, according to https://github.com/coverlet-coverage/coverlet/blob/master/Documentation/DriversFeatures.md the minimum supported version is 4.6.1.
