[Catalyst] Testing View

[Yao Wang]

Hi,

Thanks Matt. Now i know i have used wrong way to call a method in the controller.

However ,the reason i use $c->prepare is for unit testing. I have seen  Catalyst::Test and Test::WWW::Mechanize::Catalyst, i think they are the testing tools for application, not for unit testing. When i do the unit testing, i need to pass $c and some other params to the methods.
So can anybody tell me how to create this kind of $c for testing only ?

Thanks,
Yao

use Catalyst::Test 'MyApp';
use Test::WWW::Mechanize::Catalyst 'MyApp';

You can't just call ->prepare with no engine, bypass the entire dispatch
setup and then expect the dispatcher to work.

Also, a controller is an object. Calling methods as subroutines is
-just- -wrong-.
