Warning "No code coverage data available. Profiler was not initialized."

[StefH]

When running this command in a powershell script:

dotnet-coverage collect -s "codecoverage.xml" -f cobertura -o coverageFile.xml "dotnet test ./MyTest.csproj --no-build --configuration Release --results-directory TestResults --logger trx --collect `"XPlat Code Coverage;Format=cobertura`""

I get a warning: No code coverage data available. Profiler was not initialized. and indeed the coverageFile.xml is empty:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<coverage line-rate="1" branch-rate="1" complexity="1" version="1.9" timestamp="1721989043">
  <packages />
</coverage>

Note that both the project and the testproject are a net6.0 project with RuntimeIdentifier win-x86.

And using a net48 project + test project works fine.

dotnet test ./MyTest.csproj --no-build --configuration Release --results-directory TestResults --logger trx --collect "XPlat Code Coverage;Format=cobertura"

You are running tests with coverlet coverage collector ("XPlat Code Coverage") and not Microsoft Code Coverage collector. Try running without specifying --collect to dotnet test.

This yields the same warning and the coverageFile.xml is empty.

Can you run with logs and share these? dotnet-coverage collect "dotnet test test.dll" -l log.txt -ll Verbose

See attached log file.

From the logs, your dll is being skipped. Do you have some additional include/exclude in the runsettings file? Is it also possible that your dll is skipped because it contains reserved names which are skipped automatically.

Good catch ! Thank you.

The other .NET48 projects where an exe, so I used these settings in the config file:

<ModulePaths>
    <Include>
        <ModulePath>.*MyCompanyName.*\.exe$</ModulePath>
       </Include>
</ModulePaths>

But apparently, although an exe should be generated, for this .NET 6 project I need to include the dll.

After changing the settings file, it works correct.

[fhnaseer]

Include/Exclude are regular expressions. You can also use <ModulePath>.*MyCompany\.[^/\\]+\.(dll|exe)$</ModulePath> or only company name and ignore extension.
