Cobertura report shows NaN for all complexities

Expected Behavior Creating the Cobertura report type should include Cycolmatic Complexity, and highlight Risk Hotspots.

Observed Behavior

• Step 1: Run dotnet test --collect:"XPlat Code Coverage" --settings .\coverlet.runsettings.xml on a .Net Core 3.0 project
  • coverlet.runsettings.xml:

  <?xml version="1.0" encoding="utf-8" ?>
  <RunSettings>
    <DataCollectionRunSettings>
      <DataCollectors>
        <DataCollector friendlyName="XPlat code coverage">
          <Configuration>
            <Format>cobertura</Format>
            <Exclude>[*.Tests]*</Exclude>
            <IncludeTestAssembly>false</IncludeTestAssembly>
          </Configuration>
        </DataCollector>
      </DataCollectors>
    </DataCollectionRunSettings>
  </RunSettings>
  

• Step 2: run reportgenerator "-reports:*\TestResults\*\*.xml" "-targetdir:coveragereport" -reporttypes:""HTMLInline_AzurePipelines;Cobertura" on a .Net Core 3.0 project,

The HTML Report shows cyclomatic complexity numbers, and risk hotspots as expected. The Cobertura.xml file has complexity="NaN" for every package, class, and method. And since all complexities are NaN, no Risk Hotspots show.

Merged this into develop branch. Next release will contain your changes.

Will test this in several scenarios. But may take a while, since I’m on vacation.
