Is there a way to disable 'dub test' for applications?

[Jon D via Digitalmars-d-learn]

I have an dub config file specifying a targetType of 
'executable'. There is only one file, the file containing main(), 
and no unit tests.

When I run 'dub test', dub builds and runs the executable. This 
is not really desirable. Is there a way to set up the dub 
configuration file to disable running the test?

Note: What I'd really like to do is run a custom shell command 
when 'dub test' is done, I haven't seen anything suggesting 
that's an option. However, disabling would still be useful.
