117 | =head1 DESCRIPTION |
118 | |
1d85c76d |
119 | This module provides some basic Test::Builder compatible test methods to |
120 | use when writing tests for you MooseX::Daemonize based modules. |

126 | =item B<daemonize_ok ( $daemon, ?$msg )> |
7d7115e5 |
127 | |
1d85c76d |
128 | This will attempt to daemonize your C<$daemon> returning ok on |
fe0eeebc |
129 | success and not ok on failure. |
7d7115e5 |
130 | |
fe0eeebc |
131 | =item B<check_test_output ( $daemon )> |
7d7115e5 |
132 | |
1d85c76d |
133 | This is expected to be used with a C<$daemon> which does the |
fe0eeebc |
134 | B<Test::MooseX::Daemonize::Testable> role (included in this package |
1d85c76d |
135 | see the source for more info). It will collect the test output |
136 | from your daemon and apply it in the parent process by mucking |
137 | around with L<Test::Builder> stuff, again, read the source for |
fe0eeebc |
138 | more info. If we get time we will document this more thoroughly. |
