I’m getting this error when I attempt to run the XUnit command.

Error:  
Stage Controller

There was an error with stage: Unit Tests. Message: Exception: ArgumentOutOfRangeException

Message: Specified argument was out of the range of valid values.

Stack Trace: at Continua.Modules.Builds.Actions.XUnitAction.GetNuGetXUnitVersionString()  
at Continua.Modules.Builds.Actions.XUnitAction.GetFirstAdditionalAction(IBuildSteppingContext context, ActionExecutionTiming executionTiming)  
at Continua.Stepping.SteppingEngine`1.RunFrom(Action startAction) at Continua.Modules.Builds.Agent.AgentBuildRunner.OnExecuting(Transition`1 inState)

(on Agent: phus-tfsagt01)

The image below is the current setup I have in the XUnit action. The only change I’ve made from the default is the path to the Tests.dll. Any idea what I may be doing wrong, or what might be missing in our setup? I have triple checked the path with the variables, though I haven’t tried it without the variables yet.

Thanks!

Hi aszuul,

Thank you for reporting this. We have confirmed that this is a bug. When version `2.4.1` was added to the `XUnit Version` list, we omitted to add some related code. We’ve now implemented a fix and should have a new version out in the next day or two.

Meanwhile you should be able to work around this either by selecting `2.4` or `Custom` for the `XUnit Version`. If you choose `Custom`, enter the `XUnit Runner Version` as `2.4.1`
