Run Coverlet Report

A Visual Studio 2019 Extension to make showing code coverage easy.

What is it

The aim of this extension is to make something similar to the functionality provided by the Enterprise edition of Visual Studio, without the cost. Run Coverlet Report builds upon the excellent Coverlet and Report Generator tools that allow you to collect code coverage results from unit tests. This extension will run the two tools and then display the report file within visual studio as well as use the Coverlet output to provide syntax highlighting.

Installation

1. Install the Visual Studio extension.

2. Install Report Generator as a global tool Follow this guide https://github.com/danielpalme/ReportGenerator/releases

3. In your unit test projects add the Coverlet.MSBuild nuget package (due to a bug Coverlet.Collector support will be added in future).

Usage

Once installed click Tools | Run Code Coverage in Visual Studio. 'dotnet test' will then execute your unit tests and after a few moments (provided all of your tests pass) a report generator window will open showing the ReportGenerator output. C# syntax in your .cs files will also be highlighted to indicate your code coverage.

• Red background = uncovered code.
• Green background = covered code
• Orange background = a part covered line.

Version History
