29 | =head1 DEVELOPERISH RELEASE |
1cdeb21f |
30 | |
de35f86c |
31 | This is still a test release. It's working for me in production, but |
1cdeb21f |
32 | it depends on a Java application (SeleniumRC), which can be |
33 | unreliable. On my Debian system, I had to put C<firefox-bin> in my |
34 | path, and add C</usr/lib/firefox> to C<LD_LIBRARY_PATH>. Every distro |
35 | and OS is different, so I'd like some feedback on how this works on |
36 | your system. I would like to find a clean solution that lets this |
37 | module "Just Work" for everyone, but I have a feeling that it's going |
38 | to look more like C<if(gentoo){ ... } elsif (debian) { ... }> and so |
39 | on. I can live with that, but I need your help to get to that stage! |
40 | |
41 | Please report any problems to RT, the Catalyst mailing list, or the |
42 | #catalyst IRC channel on L<irc.perl.org>. Thanks! |

44 | =head1 SYNOPSIS |
45 | |
374611f4 |
46 | use Test::WWW::Selenium::Catalyst 'MyApp', 'command line to selenium'; |
4f6d213e |
47 | use Test::More tests => 2; |
48 | |
49 | my $sel = Test::WWW::Selenium::Catalyst->start; |

51 | $sel->is_text_present_ok('Welcome to MyApp'); |
52 | |
1cdeb21f |
53 | This module starts the SeleniumRC server and your Catalyst app so that |
54 | you can test it with SeleniumRC. Once you've called |
6fd21f2e |
55 | C<< Test::WWW::Selenium::Catalyst->start >>, everything is just like |
1cdeb21f |
56 | L<Test::WWW::Selenium|Test::WWW:Selenium>. |

58 | =head1 METHODS |
4f6d213e |
59 | |
374611f4 |
60 | =head2 start(\%args) |
4f6d213e |
61 | |
374611f4 |
62 | Starts the Selenium and Catalyst servers, and returns a pre-initialized, |
63 | ready-to-use Test::WWW::Selenium object. |
4f6d213e |
64 | |
374611f4 |
65 | Arguments: |
66 | |
67 | =over |
68 | |
69 | =item app_uri |
70 | |
71 | URI at which the application can be reached. If this is specified then no |
72 | application server will be started. |
73 | |
74 | =item port |
75 | |
8f552b3b |
76 | B<Default>: 3000 |
77 | |
374611f4 |
78 | Port on which to run the catalyst application server. The C<MYAPP_PORT> |
79 | environment variable is also respected. |
80 | |
81 | |
82 | =item selenium_class |
83 | |
84 | B<Default>: Test::WWW::Selenium |
85 | |
86 | Classname of Selenium object to create. Use this if you want to subclass |
87 | selenium to add custom logic. |
88 | |
89 | =item selenium_host |
90 | |
91 | =item selenium_port |
92 | |
93 | Location of externally running selenium server if you do not wish this module |
8f552b3b |
94 | to control one. See also for details. |
374611f4 |
95 | |
96 | =back |
97 | |
98 | All other options passed verbatim to the selenium constructor. |
99 | |
8f552b3b |
100 | B<NOTE>: By default a selenium server is started when you C<use> this module, |
101 | and it's killed when your test exits. If wish to manage a selenium server |
102 | yourself, (for instance you wish to start up a server once and run a number of |
103 | tests against it) pass C<-no_selenium_server> to import: |
374611f4 |
104 | |
105 | use Test::WWW::Selenium 'MyApp' |
8f552b3b |
106 | -no_selenium_server => 1 |
374611f4 |
107 | |
108 | Along a similar vein you can also pass command line arguments to the selenium |
109 | server via C<-selenium_args>: |
110 | |
111 | use Test::WWW::Selenium 'MyApp' |
8f552b3b |
112 | -selenium_args => "-singleWindow -port 4445" |
4f6d213e |
113 | |
114 | =head2 sel_pid |
115 | |
116 | Returns the process ID of the Selenium Server. |
117 | |
118 | =head2 app_pid |
119 | |
120 | Returns the process ID of the Catalyst server. |

274 | =head1 ENVIRONMENT |
275 | |
276 | Debugging messages are shown if C<CATALYST_DEBUG> or C<MYAPP_DEBUG> |
277 | are set. C<MYAPP> is the name of your application, uppercased. (This |
278 | is the same syntax as Catalyst itself.) |
279 | |
374611f4 |
280 | C<CATALYST_SERVER> can be set to test against an externally running server, |
281 | in a similar manner to how L<Test::WWW::Mechanize::Catalyst> behaves. |
282 | |
283 | The port that the application sever runs on can be affected by C<MYAPP_PORT> |
284 | in addition to being specifiable in the arguments passed to start. |
285 | |
4f6d213e |
286 | =head1 DIAGNOSTICS |
287 | |
288 | =head2 Specify your app's name |
289 | |
290 | You need to pass your Catalyst app's name as the argument to the use |
291 | statement: |
292 | |
293 | use Test::WWW::Selenium::Catalyst 'MyApp' |
294 | |
295 | C<MyApp> is the name of your Catalyst app. |
