NUnit quits while starting with little information

[erict-powersoft]

VS2017 - 15.9.7
test project has NUnit 3.11.0, NUnit3TestAdapter 3.13.0. All projects build for Any CPU, test settings processor architecture set to x86.

When I select a single test, and run selected test, I get:
[2019-03-07 09:32:09 Informational] ------ Run test started ------
[2019-03-07 09:32:09 Informational] NUnit Adapter 3.13.0.0: Test execution started

[2019-03-07 09:32:10 Informational] ========== Run test finished: 0 run (0:00:01.6208318) ==========

I don't know if the reason for the failed to load is the testcase filter mention. These tests worked on my previous computer, but I had to get a new computer.

When run with nunit3-console, I get an overall result: Passed, but all counts are 0.

Any hints on how to get my tests running again are appreciated.

Can you please upload a repro project?
Make it as small as you can, it should compile "as is".

NUnitTest.zip
I left the object files in, because your rebuild will probably work (Murphy's law). I tried various things from Stackoverflow and elsewhere, but can't make it work. Thanks for your help

Just updated VS 2017 to latest version 15.9.8. No change.

And the repro works on my machine, not surprisingly, because it is the very basic.


One thing I noted (that should not affect this issue though), is that you include the NUnit.ConsoleRunner. That one is not needed. But it should not cause any issues either, and it works on my machine.

How does it look in the Test Explorer ?

Do you have the vsix adapter installed also ? If you have, please uninstall it.

Also, check if you have an outdated test cache, see this comment #261 (comment) , and delete the whole folder pointed to there.

Hi, sorry about the delay. I just removed the vsix adapter - which was also installed. That solved the problem, it now doesn't quit shortly after starting, but finds the test and hits the breakpoint.
Thanks for solving this for me.

@erict-powersoft Thanks for confirming that it was the vsix. Strange that it blocked the tests, haven't seen that earlier, but can be versioning, since the vsix takes precedence.

I'll close this :-)

Specifically, I could see all the tests, and I could pick one, and try to run it. It would start up, and immediately quit again because it couldn't find the test then.

Yes, you see them because the Source Based Discovery (aka Real Time Test Discovery) in Visual Studio finds them, but the adapter is not invoked for that. It is then first when you try to run them the adapter is invoked. Makes me think that Visual Studio should check that it really has a workable adapter up front. Should not cost too much wrt a call.
