Test::WWW::Mechanize::Catalyst::WithContext - T::W::M::C can now give you $c

Coverage Status


Version 0.01


    use Test::WWW::Mechanize::Catalyst::WithContext;

    my $mech = Test::WWW::Mechanize::Catalyst::WithContext->new( catalyst_app => 'Catty' );

    my ($res, $c) = $mech->get_context("/"); # $c is a Catalyst context
    is $c->stash->{foo}, "bar", "foo got set to bar";

    $mech->post_ok("login", { u => "test", p => "secret" });
    my ($res, $c) = $mech->get_context("/");
    is $c->session->{stuff}, "something", "things are in the session";


Test::WWW::Mechanize::Catalyst::WithContext is a subclass of Test::WWW::Mechanize::Catalyst that can give you the $c context object of the request you just did. This is useful for testing if things ended up in the stash correctly, if the session got filled without reaching into the persistence layer or to grab an instance of a model, view or controller to do tests on them. Since the cookie jar of your $mech will be used to fetch the context, things like being logged into your app will be taken into account.

Besides that, it's just the same as Test::WWW::Mechanize::Catalyst. It inherits everything and does not overwrite any functionality. See the docs of Test::WWW::Mechanize::Catalyst for more details.



Does a GET request on $url and returns the HTTP::Response and the request context $c.

    my ( $res, $c ) = $mech->get_context('/');

This is not a get_ok and does not create test output.


The following section gives a few examples where it's useful to have $c.

Are we loading the right template?

If the content that comes out of your application does not really contain any distinct markers it's very hard to check if the right stuff got rendered. Instead of trying to find something in your HTML that helps you identify the right page with one of the content checking methods like content_like, you can just look at the template name in the stash. Of course that doesn't tell you if it got rendered successfully, but it does tell you which template the controller decided should be rendered.

    my ( $res, $c ) = $mech->get_context('/hard/to/verify/page);
    is $c->stash->{template}, 'hard_to_verify.tt2', 'the right template got selected';

Checking what's in the session without talking to the store

If you want to look at values in the session before and after some action, you would typically go and connect to the session store and peek around. For that, you need to know the type of the store, how to connect to it, and your current test user's session id. This is relatively trivial if a database (e.g. with Test::DBIx::Class), but gets more complicated when you're not mocking the store and it's something a little more esoteric. Of course you could use a different store for your unit tests, but maybe you don't want to do that.

Enter Test::WWW::Mechanize::Catalyst::WithContext. Just grab the context before and after you perform your action and look at the sessions.

    # we don't need the response object for this request
    (undef, my $c_before) = $mech->get_context('/'); # or some other url
    my ( $res, $c_after ) = $mech->get_context('/change/session');
    isnt $c_before->session->{foo}, $c_after->session->{foo}, 'foo got changed';

Of course this could be arbitrarily complex.
