Test2::Tools::Tester − Tools to help you test other testing tools.
This is a collection of tools that are useful when testing other test tools.
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");

};
# 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;
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'),
# ]
