Unit Test Sessions reports "Inconclusive: Test not run"

Hello Michael!

Thank you for contacting us.

Could you please try clearing and rebuilding solution and check if it help?

If the problem persists please start VS with the following command: 'devenv /ReSharper.LogFile C:\log\resharper_log.txt /ReSharper.LogLevel Verbose', reproduce the issue and send log file to us (via 'Sumbit a request' form).

Thank you.

Sure.  Did a clean then rebuild.  Sending you the file now.

Thanks again!  Ticket #1259424

Any update on this?

Are you including MSTest.TestAdapter in that specifik project? It compiles fine and works in Visual Studios testrunner without it.
I've had the same problem when it wasn't included. As soon as I added the package it works...

Yup, here's my packages.config file on that particular project:

<packages>
 <package id="Common.Logging" version="3.3.1" targetFramework="net452" />
 <package id="Common.Logging.Core" version="3.3.1" targetFramework="net452" />
 <package id="FluentAssertions" version="4.19.2" targetFramework="net452" />
 <package id="log4net" version="2.0.3" targetFramework="net452" />
 <package id="Microsoft.ApplicationServer.Caching.Client" version="1.0.4657.2" targetFramework="net452" />
 <package id="MSTest.TestAdapter" version="1.1.18" targetFramework="net452" />
 <package id="MSTest.TestFramework" version="1.1.18" targetFramework="net452" />
 <package id="Newtonsoft.Json" version="10.0.2" targetFramework="net452" />
 <package id="Quartz" version="2.5.0" targetFramework="net452" />
 <package id="StackExchange.Redis" version="1.2.4" targetFramework="net452" />
</packages>

Even when I do a complete rebuild, this occurs on most of my tests. I am using .Net Core 2.1 with a targetFramework of netcoreapp2.0. I disabled the shadow copy. MSTest.TestAdapter and MSTestFramework are in the PackageReference(s), although mine are version 1.2.0. I am using the latest version of Visual Studio and Resharper (not beta).

Even when it works, if I click on the test and then the panel to the right, it wipes out the results, clearing the panel, and switches it to "Inconclusive". It would be great if there were a better error message as to WHY it is "Inconclusive".

I will follow your directions for creating the log file and submit it.

Bug occurs with new Resharper version too:

MS Test Unit Tests can be executed, but not debugged. Error: Inconclusive. Test not run

We are using Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll Version 10.0.0

Hello Stgu!

Thank you for the feedback.

Is there any chance you could provide us a sample solution demonstrating the issue? You can do it privately via 'Sumbit a request' form.

Thank you.

This is just another data point. This problem was getting really hard to deal with, and then I got a notification of an update to 2017.3.5 build on 2018-03.23. So I installed it and all my problems went away! Yeah! The Visual Studio version is Enterprise 2017 (version 15.5.27130.0).

I have started getting a similar issue the last few days using 2018.1.

I have a suite of XUnit tests, which have been working fine for the past year.

Now, when I choose "Run All Tests from Solution", nothing appears to happen. The Unit Test window doesn't even open. If I manually open the Unit Test window (Ctrl+Alt+R), the tests look like they are trying to run: the 'loading' bar is animated, and the "Run" icons are disabled. However there is no indication of any activity other than that, and even after a few minutes of waiting, the tests never run. The "Stop" buttons are also disabled, so I have to restart Visual Studio to stop the test runner doing whatever it thinks it's doing.

Like the original post, sometimes I am able to run individual or groups of tests successfully by clicking "Run" in the Unit Test session window. This then seems to cause Resharper to start behaving normally again. However this is not always the case, and sometimes individual tests will not run. I haven't worked out what causes it to behave differently sometimes.

I am seeing this too, but only on static methods of a small static utility class I have for modifying strings. I can run the tests just fine individually, but not reliably by running "all" tests for a c# file, project, or solution. I have had issues like this before with ReSharper and XUnit (not always with static types). It is a recurring problem that seemingly emerges from time to time.

Same issues here

The issue I mentioned above seems to be better after upgrading my project's references to xunit and xunit.runner.visualstudio to the latest version.

Sorry, I spoke too soon. I am still receiving the issue, even after upgrading the xunit DLLs. It is quite intermittent though, and I haven't figured out a reliable work around, other than restarting Visual Studio, lots of cleaning and rebuilding etc.

I have the same problem since I updated to ReSharper 2018.1 Things were working fine until then.
I have VS 15.6.6. I am wondering will updating to visual studio 15.6.7 make it better or worse?

Started having the same issue using NUnit for all tests using TestCaseSource attribute. Sometimes they would still run, but in most case would get the error as others mention.

JetBrains ReSharper Ultimate 2018.1 Build 112.0.20180414.70444
dotCover 2018.1.20180414.124358
dotTrace 2018.1.20180414.71711
ReSharper 2018.1.20180414.71556
dotMemory 2018.1.20180414.71710

Visual Studio Professional 2017 (version 15.5.27130.2036).

UPDATE: Seems like it only happens for generic test methods, like:

[TestCaseSource(nameof(ValuesToCache))]
public void Get_GivenValueWasPut_ReturnsValueThatWasPut<T>(T value)

Try to debug the failing test. I discovered that way that this exception was caused by a StackOverflowException in one of my tested methods. See also https://youtrack.jetbrains.com/issue/RSRP-470510 

This could be caused by other test session being still active somewhere in background. Verify you don't have 'dotnet' stale processes running in background.

I am having the same problem. I submitted a bug for this way back in April (4 months ago), and as far as I can tell, no one has looked at it yet.

https://youtrack.jetbrains.com/issue/RSRP-469301

I am seeing that when I run all unit tests for an entire project, I get about half of the 70 tests failing, but when I run each of those tests individually, they all pass just fine.  The same thing happens when I run "Cover All Tests From Solution".   The same projects show about half of the tests failing, but when I run the tests individually, they pass.   

@Seansinykin I ran into the same issue when your test fixture class retains some sort of a context between tests. If you run them individually the fixture is created and destroyed. But if you run them all, the context is retained and may cause your tests to fail. To avoid this you can create all the context, like mocks etc., in the setup method. This way it will be recreated for each test.

Hello!

Thank you all for your feedback.

To begin with let me suggest to try the latest ReSharper 2018.2 EAP build and check if the problem is still reproduced - https://www.jetbrains.com/resharper/eap/

Thank you.

Hi,

unfortunately the issue still persists in my case after updating Resharper to said EAP version.

Still an issue here with Resharper 18.2.1. Come on guys get this fixed! This is the only reason I PAY you guys every damn year for my license.

This also happened to me. While I was doing a timed technical test for an interview. Thanks a lot guys.

I tried with a .NET Core 2.0 class library and also a .NET framework one. 

I tried restarting visual studio. I updated resharper to the latest version (Resharper ultimate 2018.2.1 built on 29-08-2018). Still have the same problem.

I cleared the cache and restarted visual studio. Still happened. 

I'm using NUnit 3.10.1.

Hey guys, 

Same issue here. I'm using C++ ReSharper with Google Tests and when I click on one of the tests or all of them, it won't run them with this error.

This happens in Debug and Release mode while trying to test a library project.

Hello Gilad!

Thank you for contacting us.

Could you please specify what kind  test binaries you're using?

Please note that debugging 64-bit C++ test binaries could lead to inconclusive test status as ReSharper is not able to read the process output.

Thank you.

Hello Smhoff256!

Could you please check the latest ReSharper 2018.2.2 - https://www.jetbrains.com/resharper/download/ and check if the problem is still reproduced?

Thank you.
