NAME

Test2::Tools::Tester - Tools to help you test other testing tools.

DESCRIPTION

This is a collection of tools that are useful when testing other test tools.

SYNOPSIS

use Test2::Tools::Tester qw/event_groups filter_events facets/;

use Test2::Tools::Basic qw/plan pass ok/;
use Test2::Tools::Compare qw/is like/;

my $events = intercept {
    plan 11;

    pass('pass');
    ok(1, 'pass');

    is(1, 1, "pass");
    like(1, 1, "pass");
};

# Grab events generated by tools in Test2::Tools::Basic
my $basic = filter $events => 'Test2::Tools::Basic';

# Grab events generated by Test2::Tools::Basic;
my $compare = filter $events => 'Test2::Tools::Compare';

# Grab events generated by tools named 'ok'.
my $oks = filter $events => qr/.*::ok$/;

my $grouped = group_events $events;
# Breaks events into this structure:
{
    '__NA__' => [ ... ],
    'Test2::Tools::Basic' => {
        '__ALL__' => [ $events->[0], $events->[1], $events->[2] ],
        plan => [ $events->[0] ],
        pass => [ $events->[1] ],
        ok => [ $events->[2] ],
    },
    Test2::Tools::Compare => { ... },
}

# Get an arrayref of all the assert facets from the list of events.
my $assert_facets = facets assert => $events;
# [
#   bless({ details => 'pass', pass => 1}, 'Test2::EventFacet::Assert'),
#   bless({ details => 'pass', pass => 1}, 'Test2::EventFacet::Assert'),
# ]

# Same, but for info facets
my $info_facets = facets info => $events;

EXPORTS

No subs are exported by default.

$array_ref = filter $events => $PACKAGE

$array_ref = filter $events => $PACKAGE1, $PACKAGE2

$array_ref = filter $events => qr/match/

$array_ref = filter $events => qr/match/, $PACKAGE

This function takes an arrayref of events as the first argument. All additional arguments must either be a package name, or a regex. Any event that is generated by a tool in any of the package, or by a tool that matches any of the regexes, will be returned in an arrayref.

$grouped = group_events($events)

This function iterates all the events in the argument arrayref and splits them into groups. The resulting data structure is:

{ PACKAGE => { SUBNAME => [ $EVENT1, $EVENT2, ... }}

If the package of an event is not known it will be put into and arrayref under the '__NA__' key at the root of the structure. If a sub name is not known it will typically go under the '__ANON__' key in under the package name.

In addition there is an '__ALL__' key under each package which stores all of the events sorted into that group.

A more complete example:

{
    '__NA__' => [ $event->[3] ],
    'Test2::Tools::Basic' => {
        '__ALL__' => [ $events->[0], $events->[1], $events->[2] ],
        plan => [ $events->[0] ],
        pass => [ $events->[1] ],
        ok => [ $events->[2] ],
    },
}

$arrayref = facets TYPE => $events

This function will compile a list of all facets of the specified type that are found in the arrayref of events. If the facet has a Test2::EventFacet::TYPE package available then the facet will be constructed into an instance of the class, otherwise it is left as a hashref. Facet Order is preserved.

my $assert_facets = facets assert => $events;
# [
#   bless({ details => 'pass', pass => 1}, 'Test2::EventFacet::Assert'),
#   bless({ details => 'pass', pass => 1}, 'Test2::EventFacet::Assert'),
# ]
