Test build step in TFS 2017 does not appear to run

Question

I have been setting up build configurations in TFS 2017.

As part of the build configuration I have Test steps.

When the build runs the test steps seems to run without error.

I committed some code in with a test I set to fail, to make sure that TFS stopped the build in the event tests fail. I queued a new build and then surprisingly the build completed with no issue.

I am having this issue on full framework libraries, that are being packaged into NuGet packages and also having it with .net core projects.

On evaluating the log for the test step I see the following messages.

These are from a .Net Core build

The build log

The build step for a core project

These ones are from a full framework build config

The build log for full framework

The Build Step for full framework

---

How can i set up TFS so that the tests are actually ran, and more so, the build stops if any test fails.

Further info:

I have VS 2017 installed on the build server too.

The tests are written in NUnit. Not sure if something else needs adding to the build server. Almost looks as though the build server is trying to use MSTest; i see some references to MSTestAdapter

Answer 1

VSTest task cannot run .NET core tests as it uses the Test platform version 1. To run .NET core tests, we recommend using the .NET core task with the test command.

Reference https://github.com/Microsoft/vsts-tasks/issues/5066

As a workaroun you can manually invoke vstest.console.exe from folder C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions\TestPlatform\ and provide /Framework:FrameworkCore10.

C:\Program Files (x86)>dir vstest.console.exe /s
 Volume in drive C is Windows
 Volume Serial Number is 0835-B24B

 Directory of C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Com
