The "TestCases" folder is not actually part of the project structure. Folders in either the Script section or the Keyword Tests section are simply logical organization and don't actually play a part in determining that the test is run. As per the help:
"The full name of a test should not contain the name of the Advanced folder or names of other logical project folders."
So, in your case, the command line is
/p:AccessControl_FE /t:"Script|smokeTest|Test"
Alternatively, you could do the following, using unit name and routine name switches.
/p:AccessControl_FE /u:smokeTest /rt:Test
As for the "Groups" in the test items... same thing... they are, for the most part, just organization. If you want to run a group, I think a workaround would be to create a test item that is not a group that contains the group and simply execute it. Something like
Your command line could then be
/project:project_name /test: PlaceHolder
/project:AccessControl_FE /test: DEV_AccessControl_FrontEnd
results in 'The test DEV_AccessControl_FrontEnd' was not found in the project ' AccessControl_FE'
