We are using TeamCity 2017.1.3 (build 46961).
We use xUnit plugin 1.1.2

xUnit    Runs tests written in xUnit | 1.1.2 | Capeit | <TeamCity Data Directory>\plugins\.unpacked\xUnit

Our build configuration:

• MSBuild to build app
• MSBuild to build tests: This creates some \bin\Debug in our work folder and it contains our xxx.Tests.dll
• Use xUnit to execute the tests. Runner Type xUnit, XUnit version: 2.1.0. Path to our .dll. I even tried to define the path hardcoded. I put some CMD job before to check if it was able to find the file and path and everything was fine. But the output of our xunit job is:

[09:54:46][Step 5/6] Runner parameters { Version = 2.1.0, runtime = .NET 4.5, platform = AnyCPU/MSIL}
[09:54:46][Step 5/6] Starting test runner at E:\TeamCity\buildAgent\tools\xunit-runner\bin\2.1.0\xunit.console.exe
[09:54:46][Step 5/6] No assemblies were matched - no tests will be run!

Hi,
Sorry to hear that! Could you share your folder structure and the value of the "Assemblies containing tests" parameter?

[lvthillo]

@carlpett Thank you for the quick reply.
This is the input of our 'Assemblies containing tests:' parameter
%system.teamcity.build.checkoutDir%\src\app.Test\bin\Debug\name.Web.Test.dll

The environment variable exists. We're using it in other buildsteps too and we're able to 'cd' to that specific folder.

I don't really know what you mean with the folder structure. But I can tell you the following:
Path/to/workspace/:

src/
tools/
lib/
...

Inside src/ we have a test/ folder. After the execution of the job which builds our unittests, there is a bin/Debug folder in it which contains our test.dll.

Hm, it looks like I might not be expanding variables in that parameter, which would explain it. However, the search is done relative to the current working directory, which is probably identical to %system.teamcity.build.checkoutDir%, could just try to just remove that and specify src\app.Test\bin\Debug\name.Web.Test.dll instead?

[lvthillo]

@carlpett Okay, that was the issue. My apologizes! Thank you very much.

[carlpett]

No, it should work, but apparently it does not. Great that the workaround works for you, though!
I'll fix the parameter expansion as soon as possible.

I have the same issue:

Step 5/6: Run xUnit tests via `xUnit` runner (xUnit)
