[Question] How? Logging with Specflow and xUnit 2 (ITestOutputHelper injection fails)

[cobysy]

I'm trying to log verbose information during test execution.

With xUnit 2 Console, Trace, Debug capture is no longer possible,
so we must let xUnit inject ITestOutputHelper. For example into a Specflow binding like so

public SomeSteps(ITestOutputHelper outputHelper)

but Specflow complains with the message

BoDi.ObjectContainerException Interface cannot be resolved: Xunit.Abstractions.ITestOutputHelper (resolution path: ...)

What are the methods to log information with Specflow 2 and xUnit 2 combo?
For now I've reverted back to xUnit 1.9.2, but I'd rather be using 2.0.

This is something that I am having trouble with as well. It would be nice if this ITestOutputHelper object that xUnit2 provides per-test could be made accessible though something like the ScenarioContext (I figure that the Specflow Scenario -> xUnit Fact relationship is 1:1 for the purpose of Parallelism and logging - though, there's probably a better way to do that than what I am suggesting here.)

Until we include support for ITestOutputHelper for xUnit and the same for NUnit3, simple register it by your own.
Have a look at http://www.specflow.org/documentation/Context-Injection/ in the "Advanced Options" section.
Get the IObjectContainer and register the ITestOutputHelper there.

We will need to extend the generator to pick up these test helper objects and pass them to the SpecFlow runtime.

SabotageAndi: Thank you very much for the reply! I actually attempted that based off of a suggestion that I found on some Stack Overflow question. Unfortunately, it appears that the ITestOutputHelper object has to be instantiated by xUnit in order for it to be used (As per bradwilson's message at xunit/xunit#815, and Avalanchis' reply at http://stackoverflow.com/questions/36363952/logging-with-specflow-and-xunit-2-itestoutputhelper). I have been contemplating a work around in the mean time - no luck on my side yet, I'm afraid.

yeah I made the suggestion on stackoverflow, as usually thats a suitable solution. I also read that message at XUnit and realised that it wasn't going to be a viable solution. We discussed possible options for how this migth be implemented tonight and have some ideas (Nunit3 has a similar problem) so its just waiting for someone to get around to having enough time to look at this

[reidsvilleneuve]

Okay. That's good news. I very much appreciate your time!

Are there any updates as to where this issue is at?

[avonwyss]

@lavinski There is a pull request by me from August 2016 and an update to resolve merge conflicts by @Lashas83 in February. Apparently @samholder wanted to add some additional tests but that didn't happen until now. Maybe you want to contribute some?
