155 This module allows you to make requests to a Catalyst application either without
156 a server, by simulating the environment of an HTTP request using
157 L<HTTP::Request::AsCGI> or remotely if you define the CATALYST_SERVER
158 environment variable. This module also adds a few Catalyst-specific
159 testing methods as displayed in the method section.
161 The L<get|/"$content = get( ... )"> and L<request|/"$res = request( ... );">
162 functions take either a URI or an L<HTTP::Request> object.
164 =head1 INLINE TESTS WILL NO LONGER WORK
166 While it used to be possible to inline a whole testapp into a C<.t> file for a
167 distribution, this will no longer work.
169 The convention is to place your L<Catalyst> test apps into C<t/lib> in your
170 distribution. E.g.: C<t/lib/TestApp.pm>, C<t/lib/TestApp/Controller/Root.pm>,
171 etc.. Multiple test apps can be used in this way.
173 Then write your C<.t> files like so:
179 use Test::More tests => 6;
180 use Catalyst::Test 'TestApp';
184 =head2 $content = get( ... )
188 my $content = get('foo/bar?test=1');
190 Note that this method doesn't follow redirects, so to test for a
191 correctly redirecting page you'll need to use a combination of this
192 method and the L<request|/"$res = request( ... );"> method below:
194 my $res = request('/'); # redirects to /y
195 warn $res->header('location');
197 my $uri = URI->new($res->header('location'));
198 is ( $uri->path , '/y');
199 my $content = get($uri->path);
201 =head2 $res = request( ... );
203 Returns an L<HTTP::Response> object. Accepts an optional hashref for request
204 header configuration; currently only supports setting 'host' value.
206 my $res = request('foo/bar?test=1');
207 my $virtual_res = request('foo/bar?test=1', {host => 'virtualhost.com'});
211 =head2 ($res, $c) = ctx_request( ... );
213 Works exactly like L<request|/"$res = request( ... );">, except it also returns the Catalyst context object,
214 C<$c>. Note that this only works for local requests.
216 =head2 $res = Catalyst::Test::local_request( $AppClass, $url );
218 Simulate a request using L<HTTP::Request::AsCGI>.
225 require HTTP::Request::AsCGI;
227 my $request = Catalyst::Utils::request( shift(@_) );
228 _customize_request($request, @_);
229 my $cgi = HTTP::Request::AsCGI->new( $request, %ENV )->setup;
231 $class->handle_request( env => \%ENV );
233 my $response = $cgi->restore->response;
234 $response->request( $request );
240 =head2 $res = Catalyst::Test::remote_request( $url );
242 Do an actual remote request using LWP.
248 require LWP::UserAgent;
250 my $request = Catalyst::Utils::request( shift(@_) );
251 my $server = URI->new( $ENV{CATALYST_SERVER} );
253 _customize_request($request, @_);
255 if ( $server->path =~ m|^(.+)?/$| ) {
257 $server->path("$path") if $path; # need to be quoted
260 # the request path needs to be sanitised if $server is using a
261 # non-root path due to potential overlap between request path and
264 # If request path is '/', we have to add a trailing slash to the
266 my $add_trailing = $request->uri->path eq '/';
268 my @sp = split '/', $server->path;
269 my @rp = split '/', $request->uri->path;
270 shift @sp;shift @rp; # leading /
272 foreach my $sp (@sp) {
273 $sp eq $rp[0] ? shift @rp : last
276 $request->uri->path(join '/', @rp);
278 if ( $add_trailing ) {
279 $request->uri->path( $request->uri->path . '/' );
283 $request->uri->scheme( $server->scheme );
284 $request->uri->host( $server->host );
285 $request->uri->port( $server->port );
286 $request->uri->path( $server->path . $request->uri->path );
290 $agent = LWP::UserAgent->new(

317 Fetches the given URL and checks that the request was successful.
319 =head2 action_redirect
321 Fetches the given URL and checks that the request was a redirect.
323 =head2 action_notfound
325 Fetches the given URL and checks that the request was not found.
327 =head2 content_like( $url, $regexp [, $test_name] )
329 Fetches the given URL and returns whether the content matches the regexp.
331 =head2 contenttype_is
333 Check for given MIME type.
