Feature - Testing platform coverage decision not just from command line

Consider https://learn.microsoft.com/en-us/dotnet/core/testing/microsoft-testing-platform-config

This has been implemented and will be available in the next release of code coverage. You will be able to configure code coverage settings using the test config file.

testApplication.exe --coverage --config-file testconfig.json

I cannot get it to work with dotnet test like this dotnet test --coverage --config-file testconfig.json. Any suggestions?

Can you please share code coverage extension version? It should be available in 18.X version onwards.

Currently I'm using Microsoft.Testing.Extensions.CodeCoverage with version 18.1.0 (18.100.25.50303). I tried different structures in testconfig.json:

{
    "Configuration": {
        "Format": "cobertura",
        "CodeCoverage": {
            // ...
        }
    },
    // and another example
    "codeCoverage": {
        "Configuration": {
            "Format": "cobertura",
            "CodeCoverage": {
                // ...
            }
        }
    }
}

The output always produces coverage files instead of cobertura files. If I directly run the test executable as in your comment it does not work. If I transform the settings to XML and use dotnet test --coverage --coverage-settings coverage.settings then it works.

Can you please verify if test.runner is also specified in testconfig.json?

{
    "test": {
        "runner": "Microsoft.Testing.Platform"
    },
    "codeCoverage": {
        "Configuration": {
            "Format": "cobertura",
            "CodeCoverage": {
            }
        }
    }
}

Also, please check if the output folder contains yourproject.testconfig.json and has the same file contents?

I found the problem: comments are not allowed in testconfig.json.
