Reporters

Stryker supports a variety of reporters. Enabled reporters will be activated during or after your Stryker run.

The default reporters are html and progress

Html reporter

Our html reporter will output a html file that will visually display your project and all mutations. This is our recomended reporter for larger projects, since it displays large number of mutations in a clear way.

dotnet stryker --reporter "html"

Example:

html reporter

Progress reporter

This reporter outputs the current status of the mutation testrun. It has a nice visual look so you can quickly see the progress. We recomend to use this reporter on large projects. It also shows an indication of the estimated time for Stryker.NET to complete.

dotnet stryker --reporter "progress"

Example:

progress bar reporter

Dashboard reporter

The dashboard reporter will upload your stryker result as json to the stryker dashboard. To use this reporter some settings should be configured:

dotnet stryker --reporter "dashboard"

The following options are relevant when using the dashboard reporter:

Filling all settings to use the dashboard reporter can be a bit of a hassle. However, thanks to SourceLink, the repository URL and the full version (including the git SHA1) of a project can be included in the produced assembly.

Stryker uses the information computed by SourceLink to automatically retrieve the project name (github.com/organization/project) and project version, both of which are requirements for the dashboard reporter.

Enable this by adding the following to your .csproj or Directory.Build.props to enable in all your projects:

  <ItemGroup>
<PackageReference Include="DotNet.ReproducibleBuilds" Version="0.1.66" PrivateAssets="All"/>
</ItemGroup>

For more information on SourceLink and ReproducibleBuilds see SourceLink and Dotnet.ReproducibleBuilds

Cleartext reporter

It displays all files right after the mutation testrun is done. Ideal for a quick run, as it leaves no file on your system.

dotnet stryker --reporter "cleartext"

Example:

console reporter

Cleartext tree reporter

It displays all mutations right after the mutation testrun is done. Ideal for a quick run, as it leaves no file on your system. It is recommended to turn this reporter off on big projects.

dotnet stryker --reporter "cleartexttree"

Example:

Cleartext reporter

Dots reporter

A basic reporter to display the progress of the mutationtest run. It indicates in a very simple way how many mutants have been tested and their status. This is ideal to use on build servers, as it has little/no performance loss while still giving insight.

dotnet stryker --reporter "dots"

Example:

Dots reporter

Where "." means killed, "S" means survived and "T" means timed out.

Json reporter

This reporter outputs a json file with all mutation testrun info of the last run. The json is also used for the HTML reporter, but using this reporter you could use the file for your own purposes.

dotnet stryker --reporter "json"
