JetBrains Rider 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 thepage of JetBrains Rider settings Ctrl+Alt+S.
In contrast to test frameworks natively supported by JetBrains Rider, tests from VSTest adapters are only discovered after test projects are build.
Adapter ignore list
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.
