165 | =head1 DESCRIPTION |
166 | |
2f381252 |
167 | This module allows you to make requests to a Catalyst application either without |
168 | a server, by simulating the environment of an HTTP request using |
169 | L<HTTP::Request::AsCGI> or remotely if you define the CATALYST_SERVER |
e8d0f69a |
170 | environment variable. This module also adds a few catalyst |
171 | specific testing methods as displayed in the method section. |
2f381252 |
172 | |
51a75afc |
173 | The L<get> and L<request> functions take either a URI or an L<HTTP::Request> |
2f381252 |
174 | object. |

176 | =head1 METHODS |
fc7ec1d9 |
177 | |
26dd6d9f |
178 | =head2 $content = get( ... ) |
fc7ec1d9 |
179 | |
180 | Returns the content. |
181 | |
182 | my $content = get('foo/bar?test=1'); |
183 | |
f13fc03f |
184 | Note that this method doesn't follow redirects, so to test for a |
185 | correctly redirecting page you'll need to use a combination of this |
186 | method and the L<request> method below: |
187 | |
188 | my $res = request('/'); # redirects to /y |
189 | warn $res->header('location'); |
190 | use URI; |
191 | my $uri = URI->new($res->header('location')); |
192 | is ( $uri->path , '/y'); |
193 | my $content = get($uri->path); |
194 | |
26dd6d9f |
195 | =head2 $res = request( ... ); |
fc7ec1d9 |
196 | |
51a75afc |
197 | Returns a L<HTTP::Response> object. Accepts an optional hashref for request |
d9d04ded |
198 | header configuration; currently only supports setting 'host' value. |
fc7ec1d9 |
199 | |

200 | my $res = request('foo/bar?test=1'); |

201 | my $virtual_res = request('foo/bar?test=1', {host => 'virtualhost.com'}); |

205 | =head2 ($res, $c) = ctx_request( ... ); |
26dd6d9f |
206 | |
51a75afc |
207 | Works exactly like L<request>, except it also returns the Catalyst context object, |
208 | C<$c>. Note that this only works for local requests. |
