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! |

46 | use Test::WWW::Selenium::Catalyst 'MyApp'; |
47 | use Test::More tests => 2; |

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 | |
60 | =head2 start |
61 | |
62 | Starts the Selenium and Catalyst servers, and returns a |
63 | pre-initialized, ready-to-use Test::WWW::Selenium object. |
64 | |
65 | [NOTE] The selenium server is actually started when you C<use> this |
66 | module, and it's killed when your test exits. |
67 | |
68 | =head2 sel_pid |
69 | |
70 | Returns the process ID of the Selenium Server. |
71 | |
72 | =head2 app_pid |
73 | |
74 | Returns the process ID of the Catalyst server. |

197 | =head1 ENVIRONMENT |
198 | |
199 | Debugging messages are shown if C<CATALYST_DEBUG> or C<MYAPP_DEBUG> |
200 | are set. C<MYAPP> is the name of your application, uppercased. (This |
201 | is the same syntax as Catalyst itself.) |
202 | |
203 | =head1 DIAGNOSTICS |
204 | |
205 | =head2 Specify your app's name |
206 | |
207 | You need to pass your Catalyst app's name as the argument to the use |
208 | statement: |
209 | |
210 | use Test::WWW::Selenium::Catalyst 'MyApp' |
211 | |
212 | C<MyApp> is the name of your Catalyst app. |
