writing tests for the CLI are a pain too
It shouldn't be particularly difficult to do it using
script_helper.assert_python_{ok|failure}(), even though you could also check
the argument /parsing/ separately without having to launch a subprocess.

I think it would be better to change error message to mention the type only.
Yet one argument is that the repr of affected object can be very large, while
the type name usually is short enough. repr() even can raise an exception (e.g.
MemoryError).
