200 | =head1 DESCRIPTION |
201 | |
2f381252 |
202 | This module allows you to make requests to a Catalyst application either without |
203 | a server, by simulating the environment of an HTTP request using |
204 | L<HTTP::Request::AsCGI> or remotely if you define the CATALYST_SERVER |
0eb98177 |
205 | environment variable. This module also adds a few Catalyst-specific |
206 | testing methods as displayed in the method section. |
2f381252 |
207 | |
f98f669b |
208 | The L<get|/"$content = get( ... )"> and L<request|/"$res = request( ... );"> |
209 | functions take either a URI or an L<HTTP::Request> object. |
fc7ec1d9 |
210 | |
5f2e949d |
211 | =head1 INLINE TESTS WILL NO LONGER WORK |
212 | |
965f3e35 |
213 | While it used to be possible to inline a whole test app into a C<.t> file for |
214 | a distribution, this will no longer work. |
5f2e949d |
215 | |
216 | The convention is to place your L<Catalyst> test apps into C<t/lib> in your |
217 | distribution. E.g.: C<t/lib/TestApp.pm>, C<t/lib/TestApp/Controller/Root.pm>, |
218 | etc.. Multiple test apps can be used in this way. |
219 | |
220 | Then write your C<.t> files like so: |
221 | |
222 | use strict; |
223 | use warnings; |
224 | use FindBin '$Bin'; |
225 | use lib "$Bin/lib"; |
226 | use Test::More tests => 6; |
227 | use Catalyst::Test 'TestApp'; |

229 | =head1 METHODS |
fc7ec1d9 |
230 | |
26dd6d9f |
231 | =head2 $content = get( ... ) |
fc7ec1d9 |
232 | |
233 | Returns the content. |
234 | |
235 | my $content = get('foo/bar?test=1'); |
236 | |
f13fc03f |
237 | Note that this method doesn't follow redirects, so to test for a |
238 | correctly redirecting page you'll need to use a combination of this |
f98f669b |
239 | method and the L<request|/"$res = request( ... );"> method below: |
f13fc03f |
240 | |
241 | my $res = request('/'); # redirects to /y |
242 | warn $res->header('location'); |
243 | use URI; |
244 | my $uri = URI->new($res->header('location')); |
245 | is ( $uri->path , '/y'); |
246 | my $content = get($uri->path); |
247 | |
8fa9321c |
248 | Note also that the content is returned as raw bytes, without any attempt |
249 | to decode it into characters. |
250 | |
26dd6d9f |
251 | =head2 $res = request( ... ); |
fc7ec1d9 |
252 | |
0eb98177 |
253 | Returns an L<HTTP::Response> object. Accepts an optional hashref for request |
d9d04ded |
254 | header configuration; currently only supports setting 'host' value. |
fc7ec1d9 |
255 | |
795117cf |
256 | my $res = request('foo/bar?test=1'); |
d9d04ded |
257 | my $virtual_res = request('foo/bar?test=1', {host => 'virtualhost.com'}); |
fc7ec1d9 |
258 | |
f2e13bbd |
259 | =head2 ($res, $c) = ctx_request( ... ); |
26dd6d9f |
260 | |
f98f669b |
261 | Works exactly like L<request|/"$res = request( ... );">, except it also returns the Catalyst context object, |
51a75afc |
262 | C<$c>. Note that this only works for local requests. |
