    # Tests
    use Catalyst::Test 'TestApp';
    my $content  = get('index.html');           # Content as string

    ];

=head1 DESCRIPTION

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&lt;HTTP::Request::AsCGI&gt; 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.

The L&lt;get|/"$content = get( ... )"&gt; and L&lt;request|/"$res = request( ... );"&gt;
functions take either a URI or an L&lt;HTTP::Request&gt; object.

=head1 INLINE TESTS WILL NO LONGER WORK

While it used to be possible to inline a whole test app into a C&lt;.t&gt; file for
a distribution, this will no longer work.

The convention is to place your L&lt;Catalyst&gt; test apps into C&lt;t/lib&gt; in your
distribution. E.g.: C&lt;t/lib/TestApp.pm&gt;, C&lt;t/lib/TestApp/Controller/Root.pm&gt;,
etc..  Multiple test apps can be used in this way.

Then write your C&lt;.t&gt; files like so:

    use strict;
    use warnings;
    use FindBin '$Bin';
    use lib "$Bin/lib";
    use Test::More tests =&gt; 6;
    use Catalyst::Test 'TestApp';

=head1 METHODS

=head2 $content = get( ... )

Returns the content.

    my $content = get('foo/bar?test=1');

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&lt;request|/"$res = request( ... );"&gt; method below:

    my $res = request('/'); # redirects to /y
    warn $res-&gt;header('location');
    use URI;
    my $uri = URI-&gt;new($res-&gt;header('location'));
    is ( $uri-&gt;path , '/y');
    my $content = get($uri-&gt;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&lt;HTTP::Response&gt; object. Accepts an optional hashref for request
header configuration; currently only supports setting 'host' value.

    my $res = request('foo/bar?test=1');
    my $virtual_res = request('foo/bar?test=1', {host =&gt; 'virtualhost.com'});

=head2 ($res, $c) = ctx_request( ... );

Works exactly like L&lt;request|/"$res = request( ... );"&gt;, except it also returns the Catalyst context object,
C&lt;$c&gt;. Note that this only works for local requests.
