Specflow 3.0 incorrectly generating NUnit tests when only Specflow.MSTest package is installed

Question

Specflow is generating code behind files referencing NUnit Test Attributes when MSTest is specified as the Unit Test Provider

I updated our relatively out of data specflow version to 3.0 today by walking through this documentation

We use MsTest, so as specified I installed the Specflow.MSTest package. Here's our package.json

and I ensured that the Custom Tool field has been wiped on the feature file as well.

Quite unsure how to proceed here. According to their docs, you specify the test provider in Specflow 3 based on test provider package you install.

Answer 1

I my case adding the following in App.config file worked:

  <specFlow>
    <unitTestProvider name="xUnit" />
    <generator allowDebugGeneratedFiles="true" />
  </specFlow>
