dotnet-coverageconverter

Convert .coverage (binary format) files to .coveragexml (xml format) files to support SonarCloud Code Coverage when using VSTest@2.

Installation

Install locally:

dotnet tool install --global dotnet-coverageconverter

or

Install the tool in your yml pipeline:

- task: DotNetCoreCLI@2
  displayName: "Install tool: dotnet-coverageconverter"
  inputs:
    command: 'custom'
    custom: 'tool'
    arguments: 'update --global dotnet-coverageconverter'

Usage

• Step 1: Define a VSTest@2 task with codeCoverageEnabled: true
• Step 2: Define a CmdLine@2 task with the dotnet-coverageconverter-tool and provide the CoverageFilesFolder where the .coverage files are placed by vstest.console.exe

- task: VSTest@2
  displayName: 'VsTest'
  inputs:
    testSelector: 'testAssemblies'
    vsTestVersion: 16.0
