Incomplete coverage result information (NaN%) #602

Hello,

If I run coverlet with an explicit path to the assembly, such as:

coverlet C:\Users\Documents\GitHub\DemoApp\DemoApp.Tests\bin\Release\netcoreapp3.0\DemoApp.Tests.dll -
-target "dotnet" --targetargs "test -c Release --no-build" --format opencover

All is fine and I receive results:

However, if I try to execute the following command:

coverlet C:\Users\Documents\GitHub\DemoApp\DemoApp.Tests\ --target "dotnet" --targetargs "test -c Release
--no-build" --format opencover

I receive the following output:

Most likely my error is in the syntax I am using, but all bits of advice are welcomed.

I'm running this by a build script on Appveyor, with following install commands: dotnet tool install --global coverlet.console

Hi, in the second command you cannot pass test assembly dll but a directory path, can you try to pass correct dll path? Coverlet tool works by specifing dll asm that contains tests.

Sure, if my second input command is clearly a syntax error.
