159 This module allows you to make requests to a Catalyst application either without
160 a server, by simulating the environment of an HTTP request using
161 L<HTTP::Request::AsCGI> or remotely if you define the CATALYST_SERVER
162 environment variable. This module also adds a few Catalyst-specific
163 testing methods as displayed in the method section.
165 The L<get|/"$content = get( ... )"> and L<request|/"$res = request( ... );">
166 functions take either a URI or an L<HTTP::Request> object.
168 =head1 INLINE TESTS WILL NO LONGER WORK
170 While it used to be possible to inline a whole testapp into a C<.t> file for a
171 distribution, this will no longer work.
173 The convention is to place your L<Catalyst> test apps into C<t/lib> in your
174 distribution. E.g.: C<t/lib/TestApp.pm>, C<t/lib/TestApp/Controller/Root.pm>,
175 etc.. Multiple test apps can be used in this way.
177 Then write your C<.t> files like so:
183 use Test::More tests => 6;
184 use Catalyst::Test 'TestApp';
188 =head2 $content = get( ... )
192 my $content = get('foo/bar?test=1');
194 Note that this method doesn't follow redirects, so to test for a
195 correctly redirecting page you'll need to use a combination of this
196 method and the L<request|/"$res = request( ... );"> method below:
198 my $res = request('/'); # redirects to /y
199 warn $res->header('location');
201 my $uri = URI->new($res->header('location'));
202 is ( $uri->path , '/y');
203 my $content = get($uri->path);
205 =head2 $res = request( ... );
207 Returns an L<HTTP::Response> object. Accepts an optional hashref for request
208 header configuration; currently only supports setting 'host' value.
210 my $res = request('foo/bar?test=1');
211 my $virtual_res = request('foo/bar?test=1', {host => 'virtualhost.com'});
215 =head2 ($res, $c) = ctx_request( ... );
217 Works exactly like L<request|/"$res = request( ... );">, except it also returns the Catalyst context object,
218 C<$c>. Note that this only works for local requests.
220 =head2 $res = Catalyst::Test::local_request( $AppClass, $url );
222 Simulate a request using L<HTTP::Request::AsCGI>.
230 require HTTP::Request::AsCGI;
232 my $request = Catalyst::Utils::request( shift(@_) );
233 _customize_request($request, @_);
234 my $cgi = HTTP::Request::AsCGI->new( $request, %ENV )->setup;
236 $class->handle_request( env => \%ENV );
238 my $response = $cgi->restore->response;
239 $response->request( $request );
243 my $request = Catalyst::Utils::request(shift);
244 _customize_request($request, @_);
247 test_psgi app => $app, client => sub { $ret = shift->($request) };
254 =head2 $res = Catalyst::Test::remote_request( $url );
256 Do an actual remote request using LWP.
262 require LWP::UserAgent;
264 my $request = Catalyst::Utils::request( shift(@_) );
265 my $server = URI->new( $ENV{CATALYST_SERVER} );
267 _customize_request($request, @_);
269 if ( $server->path =~ m|^(.+)?/$| ) {
271 $server->path("$path") if $path; # need to be quoted
274 # the request path needs to be sanitised if $server is using a
275 # non-root path due to potential overlap between request path and
278 # If request path is '/', we have to add a trailing slash to the
280 my $add_trailing = $request->uri->path eq '/';
282 my @sp = split '/', $server->path;
283 my @rp = split '/', $request->uri->path;
284 shift @sp;shift @rp; # leading /
286 foreach my $sp (@sp) {
287 $sp eq $rp[0] ? shift @rp : last
290 $request->uri->path(join '/', @rp);
292 if ( $add_trailing ) {
293 $request->uri->path( $request->uri->path . '/' );
297 $request->uri->scheme( $server->scheme );
298 $request->uri->host( $server->host );
299 $request->uri->port( $server->port );
300 $request->uri->path( $server->path . $request->uri->path );
304 $agent = LWP::UserAgent->new(
309 # work around newer LWP max_redirect 0 bug
310 # http://rt.cpan.org/Ticket/Display.html?id=40260
311 requests_redirectable => [],
317 return $agent->request($request);
320 sub _customize_request {
322 my $opts = pop(@_) || {};
323 $opts = {} unless ref($opts) eq 'HASH';
324 if ( my $host = exists $opts->{host} ? $opts->{host} : $default_host ) {

331 Fetches the given URL and checks that the request was successful.
333 =head2 action_redirect
335 Fetches the given URL and checks that the request was a redirect.
337 =head2 action_notfound
339 Fetches the given URL and checks that the request was not found.
341 =head2 content_like( $url, $regexp [, $test_name] )
343 Fetches the given URL and returns whether the content matches the regexp.
345 =head2 contenttype_is
347 Check for given MIME type.
