x86 version of xunit

Is there any way to get AppVeyor to use the x86 version of xunit instead of the amd64 version (which appears to be the default)?

Several of my unit test assemblies can only run in x86 due to dependencies. When run in 64 bit mode they fail. Hence I need the x86 version of xunit.

This is not a blocking issue. I worked around this by checking the x86 runner into my github repository and manually invoke it for the tests. So I'm getting the coverage I need. Would just be nicer to have it as part of the built in setup if possible.

    Yes, sure. This how we currently do for NUnit tests. Will do theSame for xUnit. 

    Apparently, looks like xUnit is more popular than NUnit :)

    I should have specified that I still build everything for AnyCPU, I just execute the tests in x86 mode.

    Then we'll be running x86 and AnyCPU assemblies with x86 runner and x64 with x64, right?

    We've got exactly the same problem as Jared.

    Do you have an ETA for the x86 version of xunit being available or a quick workaround?

    As a quick workaround you can call x86 version of runner in your own test script. Copy the command from build console and replace runner with xunit.console.x86.exe or xunit.console.clr4.x86.exe.

    We will fix this issue today.

    Expanding on Feodor's suggestion. Here is a link to a concrete example of getting xunit to run in x86 mode by changing the appveyor.xml file.


    I've been using this for a week now and it works like a champ.

    xUnit selection has been implemented and deployed with the latest update.

    Perfect timing - I had this problem as well yesterday and now find that's been fixed!

    Keep up the good work!

    So, for example, I have an AnyCPU project that has native dependencies; I need to run the xunit tests in both a 32 and 64-bit process. How can I do that with the new update?

    You should override automatic tests discovery with your own calls to xUnit runners.

    Like this?

      - xunit.console.exe Imazen.Test.WebP\bin\Release\Imazen.Test.Webp.dll /appveyor
      - xunit.console.x86.exe Imazen.Test.WebP\bin\Release\Imazen.Test.Webp.dll /appveyor
