VS 2017 unable to see code coverage results with xunit RRS feed

  • Question

  • Hi , 

    I am using VS 2017 on ASP.NET core web api project using xunit to write unit tests. I checked each folder of the assembly and they all have pdb files. However  when I hit Test>Analyze Code Coverage > All or Selected Tests , then I get the output window of the Test which shows them being discovered and run. They all pass and are shown in the Test explorer .But I don't see the code coverage window. On another project running on nunit which is not ASP.NET Core , It is a WPF App. I am able to view the results in the separate window.

  • Hi friend,

    I got the exactly same issue as yours before.

    Code Coverage is not yet supported on .NET Core projects. This is presently a limitation.

    I've already submitted a report here:

    And Visual Studio developing team has responded it at with a comment.

    So far it seems not be fixed yet.

    A workaround is to use a tool called Opencover, so you refer this blog to make it.

    Hope it helps.

  • Use OpenCover + ReportGenerator (install them as NUGET packages).

    It is not very easy to configure so I have created the powershell script that you can put to your  solution folder.

    The main configuration parameter is a globed path to your xUnit and NUnit projects.

    $TestProjectsGlobbing = @(,'*.Test.csproj')

    The idea of the script : parse project files, collect all information, call OpenCover and ReportGenerator and open report in the browser at the end.
