POE::Test::Sequence - POE test helper to verify a sequence of events
Sorry, there isn't a synopsis at this time. However, see t/90_regression/whjackson-followtail.t in POE's test suite for a full example.
POE::Test::Sequence is a test helper that abstracts a lot of the tedious trickery needed to verify the relative ordering of events.
With this module, one can test the sequence of events without necessarily relying on specific times elapsing between them.
Create a new sequence object. Takes named parameter pairs, currently just "sequence", which references an array of steps. Each step is an array reference containing the expected event, a required parameter to that event, and a code reference for the optional next step to take after testing for that event.
my $sequence = POE::Test::Sequence->new( sequence => [ [ got_idle_event => 0, sub { append_to_log("text") } ], ..., ] );
next() uses the first two step elements to verify that steps are occurring in the order in which they should. The third element is returned by next() and is suitable for use as a goto() target. See the next() method for more details.
The next() method requires an event name and a scalar parameter. These are compared to the first two elements of the next sequence step to make sure events are happening in the order in which they should.
sub handle_start_event { goto $sequence->next("got_start_event", 0); }
test_count() returns the number of test steps in the sequence object. It's intended to be used for test planning.
use Test::More; my $sequence = POE::Test::Sequence->new( ... ); plan tests => $sequence->test_count();
