=head1 DESCRIPTION
-Test Catalyst applications.
+This module allows you to make requests to a Catalyst application either without
+a server, by simulating the environment of an HTTP request using
+L<HTTP::Request::AsCGI> or remotely if you define the CATALYST_SERVER
+environment variable. This module also adds a few Catalyst-specific
+testing methods as displayed in the method section.
-=head2 METHODS
+The L<get|/"$content = get( ... )"> and L<request|/"$res = request( ... );">
+functions take either a URI or an L<HTTP::Request> object.
-=head3 get
+=head1 INLINE TESTS WILL NO LONGER WORK
+
+While it used to be possible to inline a whole test app into a C<.t> file for
+a distribution, this will no longer work.
+
+The convention is to place your L<Catalyst> test apps into C<t/lib> in your
+distribution. E.g.: C<t/lib/TestApp.pm>, C<t/lib/TestApp/Controller/Root.pm>,
+etc.. Multiple test apps can be used in this way.
+
+Then write your C<.t> files like so:
+
+ use strict;
+ use warnings;
+ use FindBin '$Bin';
+ use lib "$Bin/lib";
+ use Test::More tests => 6;
+ use Catalyst::Test 'TestApp';
+
+=head1 METHODS
+
+=head2 $content = get( ... )
Returns the content.
my $content = get('foo/bar?test=1');
-=head3 request
+Note that this method doesn't follow redirects, so to test for a
+correctly redirecting page you'll need to use a combination of this
+method and the L<request|/"$res = request( ... );"> method below:
+
+ my $res = request('/'); # redirects to /y
+ warn $res->header('location');
+ use URI;
+ my $uri = URI->new($res->header('location'));
+ is ( $uri->path , '/y');
+ my $content = get($uri->path);
+
+Note also that the content is returned as raw bytes, without any attempt
+to decode it into characters.
+
+=head2 $res = request( ... );
+
+Returns an L<HTTP::Response> object. Accepts an optional hashref for request
+header configuration; currently only supports setting 'host' value.
-Returns a C<HTTP::Response> object.
+ my $res = request('foo/bar?test=1');
+ my $virtual_res = request('foo/bar?test=1', {host => 'virtualhost.com'});
- my $res =request('foo/bar?test=1');
+=head2 ($res, $c) = ctx_request( ... );
+
+Works exactly like L<request|/"$res = request( ... );">, except it also returns the Catalyst context object,
+C<$c>. Note that this only works for local requests.
