Scenario Description

Gather code coverage for the entire solution. Refer to the provided example for collecting coverage across all unit tests. The system automatically consolidates coverage reports from all test projects. Integration tests are excluded for simplification, as the server is not initiated during this process.

Collect code coverage using command line

git clone https://github.com/microsoft/codecoverage.git
cd codecoverage/samples/Calculator
dotnet build
dotnet test --no-build --collect "Code Coverage"

You can also use run.ps1 to collect code coverage.

Collect code coverage inside github workflow

Executing tests is automatically creating cobertura report. Then reportgenerator can be used to generate final github summary markdown.

    - name: Setup .NET
      uses: actions/setup-dotnet@v3
      with:
        dotnet-version: 7.0.x
    - name: Restore dependencies
      run: dotnet restore
    - name: Build

    - name: Upload coverage into summary
      run: cat $GITHUB_WORKSPACE/coveragereport/SummaryGithub.md >> $GITHUB_STEP_SUMMARY

Run example

Collect code coverage inside Azure DevOps Pipelines

steps:
- task: DotNetCoreCLI@2
  inputs:
    command: 'restore'
    projects: '$(solutionPath)' # this is specific to example - in most cases not needed
  displayName: 'dotnet restore'

- task: DotNetCoreCLI@2
  inputs:
    command: 'build'
    arguments: '--no-restore --configuration $(buildConfiguration)'
    projects: '$(solutionPath)' # this is specific to example - in most cases not needed
  displayName: 'dotnet build'

- task: DotNetCoreCLI@2
  inputs:
    command: 'test'
    arguments: '--no-build --configuration $(buildConfiguration) --collect "Code Coverage"'
    projects: '$(solutionPath)' # this is specific to example - in most cases not needed
  displayName: 'execute tests'

NOTE: Azure DevOps pipelines automatically recognize binary coverage report format. Code coverage results are automatically processed and published to Azure DevOps. No additional steps needed.
