209 L<Catalyst> is an elegant MVC Web Application Framework.
210 L<Test::WWW::Mechanize> is a subclass of L<WWW::Mechanize> that incorporates
211 features for web application testing. The L<Test::WWW::Mechanize::Catalyst>
212 module meshes the two to allow easy testing of L<Catalyst> applications without
213 needing to starting up a web server.
215 Testing web applications has always been a bit tricky, normally
216 requiring starting a web server for your application and making real HTTP
217 requests to it. This module allows you to test L<Catalyst> web
218 applications but does not require a server or issue HTTP
219 requests. Instead, it passes the HTTP request object directly to
220 L<Catalyst>. Thus you do not need to use a real hostname:
221 "http://localhost/" will do. However, this is optional. The following
222 two lines of code do exactly the same thing:
224 $mech->get_ok('/action');
225 $mech->get_ok('http://localhost/action');
227 Links which do not begin with / or are not for localhost can be handled
228 as normal Web requests - this is handy if you have an external
229 single sign-on system. You must set allow_external to true for this:
231 $mech->allow_external(1);
233 You can also test a remote server by setting the environment variable
234 CATALYST_SERVER; for example:
236 $ CATALYST_SERVER=http://example.com/myapp prove -l t
238 will run the same tests on the application running at
239 http://example.com/myapp regardless of whether or not you specify
240 http:://localhost for Test::WWW::Mechanize::Catalyst.
242 Furthermore, if you set CATALYST_SERVER, the server will be regarded
243 as a remote server even if your links point to localhost. Thus, you
244 can use Test::WWW::Mechanize::Catalyst to test your live webserver
245 running on your local machine, if you need to test aspects of your
246 deployment environment (for example, configuration options in an
247 http.conf file) instead of just the Catalyst request handling.
249 This makes testing fast and easy. L<Test::WWW::Mechanize> provides
250 functions for common web testing scenarios. For example:
252 $mech->get_ok( $page );
253 $mech->title_is( "Invoice Status", "Make sure we're on the invoice page" );
254 $mech->content_contains( "Andy Lester", "My name somewhere" );
255 $mech->content_like( qr/(cpan|perl)\.org/, "Link to perl.org or CPAN" );
257 This module supports cookies automatically.
259 To use this module you must pass it the name of the application. See
262 Note that Catalyst has a special developing feature: the debug
263 screen. By default this module will treat responses which are the
264 debug screen as failures. If you actually want to test debug screens,
267 $mmech->{catalyst_debug} = 1;
269 An alternative to this module is L<Catalyst::Test>.
275 Behaves like, and calls, L<WWW::Mechanize>'s C<new> method. Any params
276 passed in get passed to WWW::Mechanize's constructor. Note that we
277 need to pass the name of the Catalyst application to the "use":
279 use Test::WWW::Mechanize::Catalyst 'Catty';
280 my $mech = Test::WWW::Mechanize::Catalyst->new;
284 =head2 allow_external
286 Links which do not begin with / or are not for localhost can be handled
287 as normal Web requests - this is handy if you have an external
288 single sign-on system. You must set allow_external to true for this:
290 $m->allow_external(1);
294 The name of the Catalyst app which we are testing against. Read-only.
298 The host value to set the "Host:" HTTP header to, if none is present already in
299 the request. If not set (default) then Catalyst::Test will set this to
304 Unset the host attribute.
308 Do we have a value set for the host attribute
310 =head2 $mech->get_ok($url, [ \%LWP_options ,] $desc)
312 A wrapper around WWW::Mechanize's get(), with similar options, except the
313 second argument needs to be a hash reference, not a hash. Returns true or
316 =head2 $mech->title_is( $str [, $desc ] )
318 Tells if the title of the page is the given string.
320 $mech->title_is( "Invoice Summary" );
322 =head2 $mech->title_like( $regex [, $desc ] )
324 Tells if the title of the page matches the given regex.
326 $mech->title_like( qr/Invoices for (.+)/
328 =head2 $mech->title_unlike( $regex [, $desc ] )
330 Tells if the title of the page does NOT match the given regex.
332 $mech->title_unlike( qr/Invoices for (.+)/
334 =head2 $mech->content_is( $str [, $desc ] )
336 Tells if the content of the page matches the given string
338 =head2 $mech->content_contains( $str [, $desc ] )
340 Tells if the content of the page contains I<$str>.
342 =head2 $mech->content_lacks( $str [, $desc ] )
344 Tells if the content of the page lacks I<$str>.
346 =head2 $mech->content_like( $regex [, $desc ] )
348 Tells if the content of the page matches I<$regex>.
350 =head2 $mech->content_unlike( $regex [, $desc ] )
352 Tells if the content of the page does NOT match I<$regex>.
354 =head2 $mech->page_links_ok( [ $desc ] )
356 Follow all links on the current page and test for HTTP status 200
358 $mech->page_links_ok('Check all links');
360 =head2 $mech->page_links_content_like( $regex,[ $desc ] )
362 Follow all links on the current page and test their contents for I<$regex>.
364 $mech->page_links_content_like( qr/foo/,
365 'Check all links contain "foo"' );
367 =head2 $mech->page_links_content_unlike( $regex,[ $desc ] )
369 Follow all links on the current page and test their contents do not
370 contain the specified regex.
372 $mech->page_links_content_unlike(qr/Restricted/,
373 'Check all links do not contain Restricted');
375 =head2 $mech->links_ok( $links [, $desc ] )
377 Check the current page for specified links and test for HTTP status
378 200. The links may be specified as a reference to an array containing
379 L<WWW::Mechanize::Link> objects, an array of URLs, or a scalar URL
382 my @links = $mech->find_all_links( url_regex => qr/cnn\.com$/ );

390 =head2 $mech->link_status_is( $links, $status [, $desc ] )
392 Check the current page for specified links and test for HTTP status
393 passed. The links may be specified as a reference to an array
394 containing L<WWW::Mechanize::Link> objects, an array of URLs, or a
397 my @links = $mech->links();

403 Check the current page for specified links and test for HTTP status
404 passed. The links may be specified as a reference to an array
405 containing L<WWW::Mechanize::Link> objects, an array of URLs, or a
408 my @links = $mech->links();
409 $mech->link_status_isnt( \@links, 404,
410 'Check all links are not 404' );
412 =head2 $mech->link_content_like( $links, $regex [, $desc ] )
414 Check the current page for specified links and test the content of
415 each against I<$regex>. The links may be specified as a reference to
416 an array containing L<WWW::Mechanize::Link> objects, an array of URLs,
417 or a scalar URL name.
419 my @links = $mech->links();
420 $mech->link_content_like( \@links, qr/Restricted/,
421 'Check all links are restricted' );
423 =head2 $mech->link_content_unlike( $links, $regex [, $desc ] )
425 Check the current page for specified links and test the content of each
426 does not match I<$regex>. The links may be specified as a reference to
427 an array containing L<WWW::Mechanize::Link> objects, an array of URLs,
428 or a scalar URL name.
430 my @links = $mech->links();
431 $mech->link_content_like( \@links, qr/Restricted/,
432 'Check all links are restricted' );
434 =head2 follow_link_ok( \%parms [, $comment] )
436 Makes a C<follow_link()> call and executes tests on the results.
437 The link must be found, and then followed successfully. Otherwise,
440 I<%parms> is a hashref containing the params to pass to C<follow_link()>.
441 Note that the params to C<follow_link()> are a hash whereas the parms to
442 this function are a hashref. You have to call this function like:
444 $agent->follow_like_ok( {n=>3}, "looking for 3rd link" );
446 As with other test functions, C<$comment> is optional. If it is supplied
447 then it will display when running the test harness in verbose mode.
449 Returns true value if the specified link was found and followed
450 successfully. The HTTP::Response object returned by follow_link()
455 =head2 External Redirects and allow_external
457 If you use non-fully qualified urls in your test scripts (i.e. anything without
458 a host, such as C<< ->get_ok( "/foo") >> ) and your app redirects to an
459 external URL, expect to be bitten once you come back to your application's urls
460 (it will try to request them on the remote server.) This is due to a limitation
463 One workaround for this is that if you are expecting to redirect to an external
464 site, clone the TWMC obeject and use the cloned object for the external
