NAME

       Test2::Event - Base class for events

DESCRIPTION

       Base class for all event objects that get passed through Test2.

SYNOPSIS

           package Test2::Event::MyEvent;
           use strict;
           use warnings;

           # This will make our class an event subclass (required)
           use base 'Test2::Event';

           # Add some accessors (optional)
           # You are not obligated to use HashBase, you can use any object tool you
           # want, or roll your own accessors.
           use Test2::Util::HashBase qw/foo bar baz/;

           # Chance to initialize some defaults
           sub init {
               my $self = shift;
               # no other args in @_

               $self->set_foo('xxx') unless defined $self->foo;

               ...
           }

           1;

METHODS

       $trace = $e->trace
           Get a snapshot of the Test2::Util::Trace as it was when this event was generated

       $bool = $e->causes_fail
           Returns true if this event should result in a test failure. In general this should be
           false.

       $bool = $e->increments_count
           Should be true if this event should result in a test count increment.

       $e->callback($hub)
           If your event needs to have extra effects on the Test2::Hub you can override this
           method.

           This is called BEFORE your event is passed to the formatter.

       $call = $e->created
           Get the "caller()" details from when the event was generated. This is usually inside a
           tools package. This is typically used for debugging.

       $num = $e->nested
           If this event is nested inside of other events, this should be the depth of nesting.
           (This is mainly for subtests)

       $bool = $e->global
           Set this to true if your event is global, that is ALL threads and processes should see
           it no matter when or where it is generated. This is not a common thing to want, it is
           used by bail-out and skip_all to end testing.

       $code = $e->terminate
           This is called AFTER your event has been passed to the formatter. This should normally
           return undef, only change this if your event should cause the test to exit
           immediately.

           If you want this event to cause the test to exit you should return the exit code here.
           Exit code of 0 means exit success, any other integer means exit with failure.

           This is used by Test2::Event::Plan to exit 0 when the plan is 'skip_all'. This is also
           used by Test2::Event:Bail to force the test to exit with a failure.

           This is called after the event has been sent to the formatter in order to ensure the
           event is seen and understood.

       $todo = $e->todo
       $e->set_todo($todo)
           Get/Set the todo reason on the event. Any value other than "undef" makes the event
           'TODO'.

           Not all events make use of this field, but they can all have it set/cleared.

       $bool = $e->diag_todo
       $e->diag_todo($todo)
           True if this event should be considered 'TODO' for diagnostics purposes. This
           essentially means that any message that would go to STDERR will go to STDOUT instead
           so that a harness will hide it outside of verbose mode.

       $msg = $e->summary
           This is intended to be a human readable summary of the event. This should ideally only
           be one line long, but you can use multiple lines if necessary. This is intended for
           human consumption. You do not need to make it easy for machines to understand.

           The default is to simply return the event package name.

       ($count, $directive, $reason) = $e->sets_plan()
           Check if this event sets the testing plan. It will return an empty list if it does
           not. If it does set the plan it will return a list of 1 to 3 items in order: Expected
           Test Count, Test Directive, Reason for directive.

       $bool = $e->diagnostics
           True if the event contains diagnostics info. This is useful because a non-verbose
           harness may choose to hide events that are not in this category.  Some formatters may
           choose to send these to STDERR instead of STDOUT to ensure they are seen.

       $bool = $e->no_display
           False by default. This will return true on events that should not be displayed by
           formatters.

       $id = $e->in_subtest
           If the event is inside a subtest this should have the subtest ID.

       $id = $e->subtest_id
           If the event is a final subtest event, this should contain the subtest ID.

       $hashref = $e->TO_JSON
           This returns a hashref suitable for passing to the "Test2::Event->from_json"
           constructor. It is intended for use with the JSON family of modules, which will look
           for a "TO_JSON" method when "convert_blessed" is true.

       $e = Test2::Event->from_json(%$hashref)
           Given the hash of data returned by "$e->TO_JSON", this method returns a new event
           object of the appropriate subclass.

THIRD PARTY META-DATA

       This object consumes Test2::Util::ExternalMeta which provides a consistent way for you to
       attach meta-data to instances of this class. This is useful for tools, plugins, and other
       extensions.
