JetBrains Rider's unit test runner does not allow running two or more tests with the same ID. This rarely happens in practice, but if you do have tests with the same ID, they will appear as a single node in the Unit Tests window, and only one of them will run.
Note that test frameworks identify tests in different ways. For example, MSTest uses test-methods FQNs but NUnit uses properties of test attributes as test IDs.
JetBrains Rider helps discover and run, debug, cover, or profile unit tests . The following unit testing frameworks are supported:
NUnit — JetBrains Rider installation includes 2 bundled test runners that support versions up to 2.6.4 and up to 3.11.1 correspondingly.
To enable VSTest adapters support, select the corresponding checkbox on the Build, Execution, Deployment | Unit Testing | VSTest page of JetBrains Rider settings Ctrl+Alt+S.
With JetBrains Rider, you can execute a single unit test, all tests in a test class, file, project or solution. You can also execute any number of tests combined in a test session.
Before running coverage analysis or performance profiling, make sure that the PDB information exists for all target assemblies. The safest choice would be to build your code with the Debug build configuration.
