VSTest
ReSharper | Options | Tools | Unit Testing | Test Frameworks | VSTest
ReSharper can run tests from any custom test framework that uses Visual Studio test adapter extensibility.
To enable VSTest adapters support, select the corresponding checkbox on the Tools | Unit Testing | Test Frameworks | VSTest page of ReSharper options ( Alt+R, O ).
In contrast to test frameworks natively supported by ReSharper, tests from VSTest adapters are only discovered after test projects are build.
Use this list to specify projects that contain VSTest unit tests but do not have references to specific test adapters. This may be helpful when custom adapters are configured in a .runsettings file using the <TestAdaptersPaths> element.
To add projects to the list, use file masks — for example **TestProject?.csproj to match MyTestProject2.csproj, MyTestProject3.csproj, and so on.
If a unit test project has a reference to a test adapter, you don't need to add it to this list, but if the specified file mask includes such projects, it won't be a problem.
This list includes test adapters that should not be discovered. The adapters are identified by their executor URI attributes and their containing assemblies.
By default, the list includes adapters for all natively supported frameworks — NUnit, XUnit, and MSTest — because tests from these frameworks will be discovered without adapters.
note
ReSharper's settings are saved in settings layers, which allow you to have different settings for different solutions and to share your settings with your team.
