.NET, Cobertura, Code Climate generates invalid results

[zedseven]

Hi, I recently decided to set up Code Climate for my repository, but I've been having a lot of issues.

I generate coverage reports with Coverlet, using the following command:

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura RomanizationTests/RomanizationTests.csproj

This creates RomanizationTests/coverage.cobertura.xml. As far as I can tell this file is without issue, and correct. I then process it with the following:

./cc-test-reporter format-coverage --input-type cobertura --output RomanizationTests/codeclimate.json RomanizationTests/coverage.cobertura.xml
./cc-test-reporter upload-coverage --input RomanizationTests/codeclimate.json

The file is successfully uploaded to Code Climate, but I get the following error: With the full error:

{
  "message": "Invalid path part \"/\"",
  "file_document": "{

    \"test_report_id\"=>BSON::ObjectId('601f0378c4082a440f001a32')
  }"
}

The issue is clearly with the double / in the path, but it makes no sense. Romanization/Languages/Japanese/KanjiReadings.cs is about halfway through the file list, and there are way more files than just it in the repo.

Am I missing something obvious, or is this a known issue?

I just tried it using the lcov format instead of cobertura, and the test seems to be valid. This seems to be an issue with the Cobertura format in some regard.

@efueger Is this on our radar already?
