Resharper not debugging MSTest tests

Question

I'm using Resharper Ultimate 2017.3.1

When I try to debug a unit tests

[DataTestMethod]
[DataRow("bla", "blub")]
public void Test_When_Then() { ... }

Then the test stops debugging, changes to state inconclusive and the following error is shown in the resharper test explorer window:

Has anyone had this error too and knows how to fix it so that I can debug my unit tests again?

Thanks in advance

Answer 1

I had this error when updating ReSharper, it turned out to be a problem with the referenced NuGet packages related to Microsoft.VisualStudio.TestPlatform were outdated.

Create a new test project and compare the versions of these assemblies which will be added automatically when the project is created.

Using version 14.0.0.1 is working for me for the following assemblies:

• ReSharper 2017.3.1
• VS 2017 15.5.3
