Right, hang on.. Why are you mocking things and then loading the  
entire application?

Usually you either run the full app for system testing (with test  
config that points at a test DB or whatever), or you mock _lots of  
stuff_ (like the context class, the request and response) and unit  
test one component..

Trying to mangle methods then load the full app won't work..

If you reaaaaalllly need to do this - use Catalyst::Test 'MyApp', then  
manipulate the class after catalyst has loaded it (e.g my $meta =  
MyApp::Model::Foo->meta; $meta->remove_method('bar'); $meta- 
 >add_method('bar' => sub { die("New bar") }); )

but I'd not recommend it..
