210 L<Catalyst> is an elegant MVC Web Application Framework.
211 L<Test::WWW::Mechanize> is a subclass of L<WWW::Mechanize> that incorporates
212 features for web application testing. The L<Test::WWW::Mechanize::Catalyst>
213 module meshes the two to allow easy testing of L<Catalyst> applications without
214 needing to starting up a web server.
216 Testing web applications has always been a bit tricky, normally
217 requiring starting a web server for your application and making real HTTP
218 requests to it. This module allows you to test L<Catalyst> web
219 applications but does not require a server or issue HTTP
220 requests. Instead, it passes the HTTP request object directly to
221 L<Catalyst>. Thus you do not need to use a real hostname:
222 "http://localhost/" will do. However, this is optional. The following
223 two lines of code do exactly the same thing:
225 $mech->get_ok('/action');
226 $mech->get_ok('http://localhost/action');
228 Links which do not begin with / or are not for localhost can be handled
229 as normal Web requests - this is handy if you have an external
230 single sign-on system. You must set allow_external to true for this:
232 $mech->allow_external(1);
234 You can also test a remote server by setting the environment variable
235 CATALYST_SERVER; for example:
237 $ CATALYST_SERVER=http://example.com/myapp prove -l t
239 will run the same tests on the application running at
240 http://example.com/myapp regardless of whether or not you specify
241 http:://localhost for Test::WWW::Mechanize::Catalyst.
243 Furthermore, if you set CATALYST_SERVER, the server will be regarded
244 as a remote server even if your links point to localhost. Thus, you
245 can use Test::WWW::Mechanize::Catalyst to test your live webserver
246 running on your local machine, if you need to test aspects of your
247 deployment environment (for example, configuration options in an
248 http.conf file) instead of just the Catalyst request handling.
250 This makes testing fast and easy. L<Test::WWW::Mechanize> provides
251 functions for common web testing scenarios. For example:
253 $mech->get_ok( $page );
254 $mech->title_is( "Invoice Status", "Make sure we're on the invoice page" );
255 $mech->content_contains( "Andy Lester", "My name somewhere" );
256 $mech->content_like( qr/(cpan|perl)\.org/, "Link to perl.org or CPAN" );
258 This module supports cookies automatically.
260 To use this module you must pass it the name of the application. See
263 Note that Catalyst has a special developing feature: the debug
264 screen. By default this module will treat responses which are the
265 debug screen as failures. If you actually want to test debug screens,
268 $mmech->{catalyst_debug} = 1;
270 An alternative to this module is L<Catalyst::Test>.
276 Behaves like, and calls, L<WWW::Mechanize>'s C<new> method. Any params
277 passed in get passed to WWW::Mechanize's constructor. Note that we
278 need to pass the name of the Catalyst application to the "use":
280 use Test::WWW::Mechanize::Catalyst 'Catty';
281 my $mech = Test::WWW::Mechanize::Catalyst->new;
285 =head2 allow_external
287 Links which do not begin with / or are not for localhost can be handled
288 as normal Web requests - this is handy if you have an external
289 single sign-on system. You must set allow_external to true for this:
291 $m->allow_external(1);
295 The name of the Catalyst app which we are testing against. Read-only.
299 The host value to set the "Host:" HTTP header to, if none is present already in
300 the request. If not set (default) then Catalyst::Test will set this to
305 Unset the host attribute.
309 Do we have a value set for the host attribute
311 =head2 $mech->get_ok($url, [ \%LWP_options ,] $desc)
313 A wrapper around WWW::Mechanize's get(), with similar options, except the
314 second argument needs to be a hash reference, not a hash. Returns true or
317 =head2 $mech->title_is( $str [, $desc ] )
319 Tells if the title of the page is the given string.
321 $mech->title_is( "Invoice Summary" );
323 =head2 $mech->title_like( $regex [, $desc ] )
325 Tells if the title of the page matches the given regex.
327 $mech->title_like( qr/Invoices for (.+)/
329 =head2 $mech->title_unlike( $regex [, $desc ] )
331 Tells if the title of the page does NOT match the given regex.
333 $mech->title_unlike( qr/Invoices for (.+)/
335 =head2 $mech->content_is( $str [, $desc ] )
337 Tells if the content of the page matches the given string
339 =head2 $mech->content_contains( $str [, $desc ] )
341 Tells if the content of the page contains I<$str>.
343 =head2 $mech->content_lacks( $str [, $desc ] )
345 Tells if the content of the page lacks I<$str>.
347 =head2 $mech->content_like( $regex [, $desc ] )
349 Tells if the content of the page matches I<$regex>.
351 =head2 $mech->content_unlike( $regex [, $desc ] )

361 =head2 $mech->page_links_content_like( $regex,[ $desc ] )
363 Follow all links on the current page and test their contents for I<$regex>.
365 $mech->page_links_content_like( qr/foo/,
366 'Check all links contain "foo"' );
368 =head2 $mech->page_links_content_unlike( $regex,[ $desc ] )

371 contain the specified regex.
373 $mech->page_links_content_unlike(qr/Restricted/,
374 'Check all links do not contain Restricted');
376 =head2 $mech->links_ok( $links [, $desc ] )
378 Check the current page for specified links and test for HTTP status
379 200. The links may be specified as a reference to an array containing
380 L<WWW::Mechanize::Link> objects, an array of URLs, or a scalar URL

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

411 'Check all links are not 404' );
413 =head2 $mech->link_content_like( $links, $regex [, $desc ] )
415 Check the current page for specified links and test the content of
416 each against I<$regex>. The links may be specified as a reference to
417 an array containing L<WWW::Mechanize::Link> objects, an array of URLs,
418 or a scalar URL name.
420 my @links = $mech->links();
421 $mech->link_content_like( \@links, qr/Restricted/,
422 'Check all links are restricted' );
424 =head2 $mech->link_content_unlike( $links, $regex [, $desc ] )
426 Check the current page for specified links and test the content of each
427 does not match I<$regex>. The links may be specified as a reference to

429 or a scalar URL name.
431 my @links = $mech->links();
432 $mech->link_content_like( \@links, qr/Restricted/,
433 'Check all links are restricted' );
435 =head2 follow_link_ok( \%parms [, $comment] )
437 Makes a C<follow_link()> call and executes tests on the results.
438 The link must be found, and then followed successfully. Otherwise,
441 I<%parms> is a hashref containing the params to pass to C<follow_link()>.
442 Note that the params to C<follow_link()> are a hash whereas the parms to
443 this function are a hashref. You have to call this function like:
445 $agent->follow_like_ok( {n=>3}, "looking for 3rd link" );
447 As with other test functions, C<$comment> is optional. If it is supplied
448 then it will display when running the test harness in verbose mode.
450 Returns true value if the specified link was found and followed
451 successfully. The HTTP::Response object returned by follow_link()
456 =head2 External Redirects and allow_external
458 If you use non-fully qualified urls in your test scripts (i.e. anything without
459 a host, such as C<< ->get_ok( "/foo") >> ) and your app redirects to an
460 external URL, expect to be bitten once you come back to your application's urls
461 (it will try to request them on the remote server.) This is due to a limitation
464 One workaround for this is that if you are expecting to redirect to an external
465 site, clone the TWMC obeject and use the cloned object for the external
