Hi Daniele,

Turtle is not a boost component, so you might want to create a ticket 
for support directly to the project (see 
http://sourceforge.net/projects/turtle/support/).

A 'with' takes a constraint which general form is a functor testing the 
received argument (see 
http://turtle.sourceforge.net/turtle/customisation.html#turtle.customisation.constraints/).
The simplest solution for your problem would be a free function :

bool CheckArgs( TArgs& args )
{
     return args.msg.station_type() == EStationType::ST_CLIENT;
}

with the expectation being :

MOCK_EXPECT( mockSvr.OnMsgMethodConnect ).once().with( mock::any, 
&CheckArgs );

Of course this will quickly become tedious if you write several tests 
checking various values, and you might want to factorize things a bit.
If you need more information, just create a support ticket and I will be 
happy to help !

Cheers,
MAT.
