=head1 NAME
Test2::Tools::Grab - Temporarily intercept all events without adding a scope
level.
=head1 DESCRIPTION
This package provides a function that returns an object that grabs all events.
Once the object is destroyed events will once again be sent to the main hub.
=head1 SYNOPSIS
use Test2::Tools::Grab;
my $grab = grab();
# Generate some events, they are intercepted.
ok(1, "pass");
ok(0, "fail");
my $events_a = $grab->flush;
# Generate some more events, they are intercepted.
ok(1, "pass");
ok(0, "fail");
my $events_b = $grab->finish;
=head1 EXPORTS
=over 4
=item $grab = grab()
This lets you intercept all events for a section of code without adding
anything to your call stack. This is useful for things that are sensitive to
changes in the stack depth.
my $grab = grab();
ok(1, 'foo');
ok(0, 'bar');
my $events = $grab->finish;
is(@$events, 2, "grabbed 2 events.");
If the C<$grab> object is destroyed without calling C<finish()>, it will
automatically clean up after itself and restore the parent hub.
{
my $grab = grab();
# Things are grabbed
}
# Things are back to normal
By default the hub used has C<no_ending> set to true. This will prevent the hub
from enforcing that you issued a plan and ran at least 1 test. You can turn
enforcement back one like this:
$grab->hub->set_no_ending(0);
With C<no_ending> turned off, C<finish> will run the post-test checks to
enforce the plan and that tests were run. In many cases this will result in
additional events in your events array.
