sub bail-out ($desc?)

If you already know the tests will fail, you can bail out of the test run using bail-out():

my $has-db-connection;
...
$has-db-connection  or bail-out 'Must have database connection for testing';

The function aborts the current test run, signaling failure to the harness. Takes an optional reason for bailing out. The subroutine will call exit(), so if you need to do a clean-up, do it before calling bail-out().

If you want to abort the test run, but without marking it as failed, see skip-rest or plan :skip-all('...')
