I have already...

• repeated the problem using the latest stable release of OpenCover.
• reviewed the usage guide and usage document.
• have looked at the opencover output xml file in an attempt to resolve the issue.
• reviewed the current issues to check that the issue isn't already known.

My issue is related to (check only those which apply):

• no coverage being recorded
• 32 or 64 bit support
• feature request

Expected Behavior

Coverage report

Actual Behavior

No report

Steps to reproduce the problem:

Installed via nuget: OpenCover 4.6.519, xunit.runner.console 2.3.1

Target framework: .NET Standard 2.0 / .NET Core 2.0

OpenCover.Console.exe -register:user -output:coverage.xml -target:"dotnet.exe" -targetargs:"C:\...\packages\xunit.runner.console\2.3.1\tools\netcoreapp2.0\xunit.console.dll MyProject.Tests\bin\Debug\netcoreapp2.0\MyProject.Tests.dll" -filter:"+[MyProject*]* -[*.Tests]*"

output

Executing: C:\Program Files\dotnet\dotnet.exe
xUnit.net Console Runner (64-bit .NET Core 4.6.00001.0)
  Discovering: MyProject.Tests
  Discovered:  MyProject.Tests
  Starting:    MyProject.Tests

No results, this could be for a number of reasons. The most common reasons are:
    1) missing PDBs for the assemblies that match the filter please review the
    output file and refer to the Usage guide (Usage.rtf) about filters.
    2) the profiler may not be registered correctly, please refer to the Usage
    guide and the -register switch.

I went over the docs, but I couldn't find any examples with .net core. or xunit.

I'm hoping someone could point me in the right direction to solving this.

Cheers!

I was seeing <Module skippedDueTo="Filter" in xunit_opencovertests.xml.

After adding <DebugType>Full</DebugType> to all of my .csproj files I started to get this error:

   MyProject.Tests.SerializerTests.SerializeAndDeserializeMemoryStream [FAIL]
      System.MissingMethodException : Method not found: 'Void System.CannotUnloadAppDomainException.SafeVisited(Int32)'.
      Stack Trace:
           at MyProject.Serialization.Serializer`1.Serialize(T obj)
           at MyProject.Tests.SerializerTests.SerializeAndDeserializeMemoryStream()

I was able to get past this message by including the flag -oldstyle.

It seems like everything is working properly now.

This is my final command:

OpenCover.Console.exe -register:user -output:coverage.xml -target:"dotnet.exe" -targetargs:"C:\...\packages\xunit.runner.console\2.3.1\tools\netcoreapp2.0\xunit.console.dll MyProject.Tests\bin\Debug\netcoreapp2.0\MyProject.Tests.dll" -filter:"+[MyProject*]* -[*.Tests]*" -oldstyle

Cheers!
