create_generic_session

The create_generic_session() method creates a POE::Session that routes all vents through the POE::Test::Sequence object. It returns the POE::Session object, but the test program does not need to store it anywhere. In fact, it's recommended not to do that without understanding the implications.

The implications can be found in the documentation for POE::Kernel and POE::Session.

An example of create_generic_session() can be found in POE's t/90_regression/leolo-alarm-adjust.t test program.

new

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.

next

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

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();
