VSTS Build does not run NUnit tests

Question

When creating a visual studio solution using the services of a visual studio, it runs unit tests written in nunit 3 using the nunit 3 NUnit3TestAdapter, which runs the tests.

The error it gives is: Error: Invalid characters in the path.

Full conclusion as follows

We have a room assembly agent, but I don’t think it should matter.

Any advice you can give him is appreciated.

Answer 1

I met this problem when I used the NUnit3 Test Adapter Nuget Package during build. And I solved this by installing the NUnit3 Test Adapter and downloading all the installed files in the Control Version and using it as a test adapter.

Because you are using the room assembly agent. You can easily install the NUnit3 test adapter in the build agent and use the argument "/ UseVsixExtensions: true" as indicated by the error message.

FWIW, I have included a detailed journal, following the Tips and Tricks, and got the following:

which correlates with %LOCALAPPDATA%\NUnit\Nunit30Settings.xml , access to which is possible but cannot be connected. ExtensionService here .

Issues # 117 and # 118 are related to this with the fix provided by RobertK66 :

If you install version 3.0.8.0 as a Nuget package, then there is a damaged (not empty!) File "ignore.addins" installed in the \ NUnit3TestAdapter.3.0.8-ctp-8 \ lib packages. Previous versions installed a 0-byte empty file!

After deleting the contents of this file in / packages / NUnit 3TestAdapter.3.0.8-ctp-8 \ lib and removing the cached version of the adapter in \ AppData \ Local \ Temp \ VisualStudioTestExplorerExtensions ... everything works as expected!
