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

    package My::Event;
    use Test2::Util::Facets2Legacy ':ALL';
    sub facet_data { return { ... } }

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

    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.
