Hi,
The TinyEmbeddedTest framework is intended to be used with the barebone devices that don’t have a concept of command line (unless you are using semihosting anyway), so it doesn’t support any command-line switches. Instead you can use the Visual Studio GUI to select which of the tests to run.
If you are running tests via the VisualGDB.exe /runtests command line, we could add an option to run specific tests only there as well.
