NAME

Test2::Util::Facets2Legacy - Convert facet data to the legacy event API.

DESCRIPTION

This module exports several subroutines from the older event API (see Test2::Event). These subroutines can be used as methods on any object that provides a custom "facet_data()" method. These subroutines can also be used as functions that take a facet data hashref as arguments.

SYNOPSIS

AS METHODS

    package My::Event;

    use Test2::Util::Facets2Legacy ':ALL';

    sub facet_data { return { ... } }

Then to use it:

    my $e = My::Event->new(...);

    my $causes_fail = $e->causes_fail;
    my $summary     = $e->summary;
    ....

AS FUNCTIONS

    use Test2::Util::Facets2Legacy ':ALL';

    my $f = {
        assert => { ... },
        info => [{...}, ...],
        control => {...},
        ...
    };

    my $causes_fail = causes_fail($f);
    my $summary     = summary($f);

NOTE ON CYCLES

When used as methods, all these subroutines call "$e->facet_data()". The default "facet_data()" method in Test2::Event relies on the legacy methods this module emulates in order to work. As a result of this it is very easy to create infinite recursion bugs.

These methods have cycle detection and will throw an exception early if a cycle is detected. "uuid()" is currently the only subroutine in this library that has a fallback behavior when cycles are detected.

EXPORTS

Nothing is exported by default. You must specify which methods to import, or use the ':ALL' tag.

$bool = $e->causes_fail()
$bool = causes_fail($f): Check if the event or facets result in a failing state.
$bool = $e->diagnostics()
$bool = diagnostics($f): Check if the event or facets contain any diagnostics information.
$bool = $e->global()
$bool = global($f): Check if the event or facets need to be globally processed.
$bool = $e->increments_count()
$bool = increments_count($f): Check if the event or facets make an assertion.
$bool = $e->no_display()
$bool = no_display($f): Check if the event or facets should be rendered or hidden.
($max, $directive, $reason) = $e->sets_plan()
($max, $directive, $reason) = sets_plan($f): Check if the event or facets set a plan, and return the plan details.
$id = $e->subtest_id()
$id = subtest_id($f): Get the subtest id, if any.
$string = $e->summary()
$string = summary($f): Get the summary of the event or facets hash, if any.
$undef_or_int = $e->terminate()
$undef_or_int = terminate($f): Check if the event or facets should result in process termination, if so the exit code is returned (which could be 0). undef is returned if no termination is requested.
$uuid = $e->uuid()
$uuid = uuid($f): Get the UUID of the facets or event.
Note: This will fall back to "$e->SUPER::uuid()" if a cycle is detected and an event is used as the argument.
