Why can I only run single tests in TestDriven.net? I can't seem to run classes or files.
When this happens, it means that TestDriven.net doesn't understand xUnit.net tests, and is running your tests using the built-in Ad-Hoc Runner.
This might happen for one or more reasons:
- Did you install xUnit.net's TestDriven.net support? Run xunit.installer.exe and make sure you install TD.NET support.
- Did you recently upgrade from xUnit.net 1.0.x to xUnit.net 1.1 or later? The TD.NET runner DLL name changed. Run xunit.installer.exe and disable then re-enable TD.NET support.
- Are you running 64-bit Windows? Make sure you're running TD.NET version 2.18 or later, as some earlier versions had an issue with 64-bit Windows.
Note that after disabling and/or enabling TD.NET support, you may need to restart Visual Studio.
