nunit/nunit

The NUnit Framework is the oldest and most widely used .NET Test Framework

Julien

@LiohAu

Is there an architecture diagram somewhere that would explain which NUnit omponent uses the other components ?

Julien

@LiohAu

At first I assumed that NUnit adapter was calling the NUnit console runner, but I don't see any reference to that .exe in the code, only references to vstest

so are NUnit Adapter and NUnit Console using vstest under the hood ?

Ace Olszowka

@aolszowka

@LiohAu I don't believe that there is a block diagram, NUnit Adapter is using the actual NUnit Engine under the hood, the NUnit Console also uses that same engine but has a CLI Front end to it.

Julien

@LiohAu

@aolszowka my concerns is with the runsettings file. I just followed the vstest code, and it seems that the runsettings is given to an MSBuild .target file, then it goes into the VsTest code, and it is then given to NUnit by the NUnit classes that respect the VSTest contrat.

the thing I am trying to understand is why runsettings is ignored when using VS Mac :(

Ace Olszowka

@aolszowka

VS Mac isn't the same as VS Proper I thought it was a reskinning of Android Studio or whatever that they purchased, it might be that they do not properly support the IRunSettings interface, are you setup to debug this?

Chris Maddock

@ChrisMaddock

@radleta Does your test have a timeout attirbute by any chance? This is fixed in master so the timeout doesn't apply when the debugger is attached, but it's not released yet

Julien

@LiohAu

@aolszowka behind VS mac, it is the monodevelop IDE and no i'm not setup to debug it ^^

But I assume everything is calling vstest.console.exe in the end. So if I can submit an issue or a PR on the NUnit MonoDevelop AddIn, to pass the NUnit file which is defined in the .csproj, that could be enough

Richard Adleta

@radleta

@ChrisMaddock Unfortunately, no it does not have a timeout attribute.

Terje Sandstrom

@OsirisTerje

@LiohAu The runsettings is sent down from whoever calls the adapter. I have sent a question to the MS product group about this, referring to the issue raised here nunit/nunit3-vs-adapter#778 . Please add whatever other comments you may have to that issue, MS will read it :-)

Julien

@LiohAu

@OsirisTerje It seems that people using .NET core projects in Windows based VS or in VS Mac/MonoDevelop are all depending on VsTest. But if you are not using a .NET core based project and that NUnit is in your project, the NUnit addin in VSMac/MonoDevelop, seems to fallback to an internal runner, and I did not find yet how to provide the settings...

Terje Sandstrom

@OsirisTerje

@LiohAu Just for others to see, MS has confirmed this doesn't yet work on VS Mac, see https://github.com/nunit/nunit3-vs-adapter/issues/778#issuecomment-679292768. They suggest a command line work around until the issue is resolved

Quick Q before filing an issue... running tests with dotnet test ... and nunit3 adapter 3.16.1 does produce a complete Xml file, upgrading to adapter 3.17.0 produces an Xml file that only contains the <command-line> element - rings a bell / known issue?

Terje Sandstrom

@OsirisTerje

@zpqrtbnk No. Please raise an issue with repro :-)

Issue nunit/nunit3-vs-adapter#780 - reproduces on my project, going to try to reproduce on a smaller-scale project that I can share

Hello, Is there a way to load a dll that is targeting .net framework 4.7.2 into an asp.net core web application? I have the following error when exploring the nunit tests( Tests = new TestNode(TestEngineRunner.Explore(TestFilter.Empty));):

            LoadPackage(testFile);

            TestEngine = TestEngineActivator.CreateInstance();

            TestEngineRunner = TestEngine.GetRunner(_package);

            Tests = new TestNode(TestEngineRunner.Explore(TestFilter.Empty));

The error:

NUnit.Engine.NUnitEngineException: 'An exception occurred in the driver while loading tests.'
FileNotFoundException: Could not load file or assembly 'TestingFramework, Version=9.2.2.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

Chris Maddock

@ChrisMaddock

Hi @marius02 - not yet. See nunit/nunit-console#465 for tracking

Alberto Bar-Noy

@AlbertoBN

Hello, I have a weird problem with NUnit3-console. I am trying to run my tests via command line and have NUnit.Allure for reports in my code as well. When I call the command line the console runner is stuck and neither runs tests not produces any output even when --trace=Verbose is used... Any insights? (same question goes to allure gitter. I am at a total loss here)

The project is a full .Net framework one...

Chris Maddock

@ChrisMaddock

@AlbertoBN try running with --labels=All, see if you get stuck on a particular test?

Alberto Bar-Noy

@AlbertoBN

@ChrisMaddock No joy. Stuck on the get go... waiting 10 minutes to see a label ... :(

Alberto Bar-Noy

@AlbertoBN

OK so... I went a little bit crazy and run the project with vstest.console... and I noticed that allure is dependent on Newtonsoft.Json 12.0.0 But this dependency was not mentioned in the package. I added it and run with NUnit again and TADAAAAAAAAAA (the windows 95 one)

Chris Maddock

@ChrisMaddock

@AlbertoBN How strange - I'd have expected that to crash rather than hang. Glad you're sorted, either way! :-)

Marius Morar

@marius02

@ChrisMaddock thanks for the reply , you have any suggestions to workaround this issue(nunit/nunit-console#465)? maybe to create a wcf service and to consume it via asp.net core web application, or an web api/rest app ?

Chris Maddock

@ChrisMaddock

Hmm...what's your usecase, why do you need to run an netfx test assembly from a .NET Core test runner? Or is it that you have a single test runner and want to be able to run both .NET Core and netfx test assemblies from it?

Chris Maddock

@ChrisMaddock

Here's a thought, have you considered using NUnitLite for you .NETFX test suites? That was your test runner could just start them up in a separate process and retrieve the results? It would mean you wouldn't really be using the engine for the netfx stuff of course.

Marius Morar

@marius02

the use case: I want to parse the test dll(NETFX ) and display the tests in a asp net core web app(kind of a NUnit Gui for the web, but customized), I'm not able to alter the test dll for now, but I think I will change my approach

Daniel Abrahamsson

@danabr

I have an issue with the NUnit test agent crashing ("Remote test agent exited with non-zero exit code"). What can I do to start debugging it? My tests run fine when I run them through VS.

Daniel Abrahamsson

@danabr

It is interesting to note that I don't get any crash if I use process=Single.

Ah. I found an issue in one of my test assemblies. A StackOverflowException, so naturally the process crashes.

Mikkel Nylander Bundgaard

@mikkelbu

Usually, one can diagnose these kinds of problems by running with the flag --inprocess

Daniel Abrahamsson

@danabr

Yep, that's what I did (with the equivalent process=Single). Turned out to be that I had forgotten to enable tail calls when I converted a F# project to the new project file format. The reason I did not see the problem every time was that the test causing the trouble in turn invoked FsCheck (generating random tests).

Chris Maddock

@ChrisMaddock

@danabr FYI the next version of the NUnit Console should tell you when you hit a stackoverflow exception. :-) (If it's easy to revert your current fix, I'd be interested to know if using the v3.12 beta version would have helped here?)

Daniel Abrahamsson

@danabr

@ChrisMaddock : It is easy to revert. This is what 3.12-beta1 gives me:

Unhandled Exception: NUnit.Engine.NUnitEngineException: Remote test agent was terminated due to a stack overflow.

So that's exactly the information I was after :)

Daniel Abrahamsson

@danabr

Btw, does 3.12 drop support for the legacy nunit2 format? Using format=nunit2 I get:

NUnit.Engine.NUnitEngineException : Error encountered in resolving output specification: OutputPath: ..\Tests\TestRes
  ult.xml, Format: nunit2
    ----> System.IO.FileNotFoundException : Could not load file or assembly 'nunit.engine.api, Version=3.0.0.0, Culture

@batzen

Hi there. Is there any chance to get a pre-release of nunit 3.13 on nuget? Or is there some CI nuget feed i can use?

Chris Maddock

@ChrisMaddock

@danabr Hooray! On the nunit2 format - no - at least...not intentionally! It's a bug that needs fixing in the beta. :-)

@batzen builds of master available here: https://www.myget.org/feed/nunit/package/nuget/NUnit. Not sure on the release date sorry, might be worth asking in an issue for the right people to see.

Bastian Schmidt

@batzen

@ChrisMaddock Thx for the link. I don't want to create pressure, so there is no need for an issue. I just overlooked the mention of the myget feed in the readme. ;-)

Alberto Bar-Noy

@AlbertoBN

Hello everyone. I have a rather (IMO) unusual question. I have an assembly with tests and logging with NLog. I extended NLOG to write any logs to the console output either by using TestContext or Console.WriteLine (different set of tryouts) and I was hoping to see the logs on a TeamCity build log. Alas I only see logs from one test and the rest is only assertions. Any ideas on how to overcome this? Thanks in advance

Alberto Bar-Noy

@AlbertoBN

And to answer my own question... RTFM... TestContext.Progress.

Zach Miller

@zmmille2

Hey, I'm having trouble getting VSCode to pick up Nunit tests - is there any launch.json configuration I have to do to get this to work? I was under the impression that this should "just work" with the C# extension

Zach Miller

@zmmille2

Looks like it was an issue with the solution file - .csproj files needed to be added to the .sln file, OmniSharp looks for the different .csproj files listed in the .sln file if there is one and we hadn't added it in.

Marius Morar

@marius02

Is there a way to hide or fix this nunit warning (I have the latest one: 3.17)? or why is this triggered at the end of the running tests?

Terje Sandstrom

@OsirisTerje

@marius02 If you create a small repro and raise an issue at the NUnit3TestAdapter repo https://github.com/nunit/nunit3-vs-adapter it might be possible to fix. Hiding it, you can't. It is an exception, and we can't hide them . I see the exception starts down in the engine, so it can be an NUnit engine issue too, but if we start from the adapter we can take it from there. But, we do need a repro :-)

Marius Morar

@marius02

is someone using https://github.com/endless-qa/nunit-test-video-recorder for recording tests?
