xUnit Test Runner failed to run tests through ReSharper

Question

• Visual Studio 2015 Enterprise Update 3, all KB package updates are applied
• ReSharper 2016.1.2, latest
• According to my project.json file xunit references are;
  • "xunit": "2.2.0-beta2-build3300", "xunit.abstractions": "2.0.1-rc2", "xunit.assert": "2.2.0-beta2-build3300", "xunit.extensibility.core": "2.2.0-beta2-build3300", "xunit.extensibility.execution": "2.2.0-beta2-build3300", "xunit.runner.console": "2.2.0-beta2-build3300", "xunit.runner.visualstudio": "2.2.0-beta2-build1149", "xunit.runners": "2.0.0"
• .Net framework is 4.5.2
• .Net Core Solution type which means .xproj

When i try to use ReSharper xUnit test runner, i'm encountering;

"Unit Test Runner failed to run tests, Unable to run xUnit tests - File not found:"D:\srcs\GitProjects..etc\bin\My.Tests.dll" Parameter name: assemblyFileName

Sorry for Turkish exception details, i couldn't change yet. Any idea about that? I searched a lot of forums and i couldn't find any useful stuff. Thanks in advance.

Answer 1

Support for .NET Core testing in Resharper is scheduled for 2016.3

The workaround is to use Visual Studio Test Explorer. (Test --> Windows --> Test Explorer)

The project.json file must contain xunit and dotnet-test-xunit:

{
  ...
  "testRunner": "xunit",
  "dependencies": {
    ...
    "xunit": "2.2.0-beta2-build3300",
    "dotnet-test-xunit": "2.2.0-preview2-build1029",
  },
  ...
}

Rebuild your project and you should be able to successfully run your tests. If you have Visual Studio 2015 you can start your test inside the code.

Update: (2017-02-08) It also works with nunit;

{
  "testRunner": "nunit",
  "dependencies": {
    ...
  "NUnit": "3.5.0",  
  "dotnet-test-nunit": "3.4.0-beta-3"
  },
...
}

ReSharper doesn't currently support .net core testing. This is scheduled for 2016.3.
