151 | =head1 DESCRIPTION |
152 | |
2f381252 |
153 | This module allows you to make requests to a Catalyst application either without |
154 | a server, by simulating the environment of an HTTP request using |
155 | L<HTTP::Request::AsCGI> or remotely if you define the CATALYST_SERVER |
0eb98177 |
156 | environment variable. This module also adds a few Catalyst-specific |
157 | testing methods as displayed in the method section. |
2f381252 |
158 | |
f98f669b |
159 | The L<get|/"$content = get( ... )"> and L<request|/"$res = request( ... );"> |
160 | functions take either a URI or an L<HTTP::Request> object. |

162 | =head1 INLINE TESTS WILL NO LONGER WORK |
163 | |
164 | While it used to be possible to inline a whole testapp into a C<.t> file for a |
165 | distribution, this will no longer work. |
166 | |
167 | The convention is to place your L<Catalyst> test apps into C<t/lib> in your |
168 | distribution. E.g.: C<t/lib/TestApp.pm>, C<t/lib/TestApp/Controller/Root.pm>, |
169 | etc.. Multiple test apps can be used in this way. |
170 | |
171 | Then write your C<.t> files like so: |
172 | |
173 | use strict; |
174 | use warnings; |
175 | use FindBin '$Bin'; |
176 | use lib "$Bin/lib"; |
177 | use Test::More tests => 6; |
178 | use Catalyst::Test 'TestApp'; |

180 | =head1 METHODS |
fc7ec1d9 |
181 | |
26dd6d9f |
182 | =head2 $content = get( ... ) |
fc7ec1d9 |
183 | |
184 | Returns the content. |
185 | |
186 | my $content = get('foo/bar?test=1'); |
187 | |
f13fc03f |
188 | Note that this method doesn't follow redirects, so to test for a |
189 | correctly redirecting page you'll need to use a combination of this |
f98f669b |
190 | method and the L<request|/"$res = request( ... );"> method below: |
f13fc03f |
191 | |
192 | my $res = request('/'); # redirects to /y |
193 | warn $res->header('location'); |
194 | use URI; |
195 | my $uri = URI->new($res->header('location')); |
196 | is ( $uri->path , '/y'); |
197 | my $content = get($uri->path); |
198 | |
26dd6d9f |
199 | =head2 $res = request( ... ); |
fc7ec1d9 |
200 | |
0eb98177 |
201 | Returns an L<HTTP::Response> object. Accepts an optional hashref for request |
d9d04ded |
202 | header configuration; currently only supports setting 'host' value. |
fc7ec1d9 |
203 | |
795117cf |
204 | my $res = request('foo/bar?test=1'); |
d9d04ded |
205 | my $virtual_res = request('foo/bar?test=1', {host => 'virtualhost.com'}); |

f2e13bbd |
209 | =head2 ($res, $c) = ctx_request( ... ); |
26dd6d9f |
210 | |
f98f669b |
211 | Works exactly like L<request|/"$res = request( ... );">, except it also returns the Catalyst context object, |
51a75afc |
212 | C<$c>. Note that this only works for local requests. |
