Testing

The package's tests

composer install
vendor/bin/phpunit --no-configuration tests

The unit suite, under tests/Unit, runs without a kernel, a database or a network: it builds both events with every kind of language tag and owner identifier, accepted and refused, at their length limits. In the monorepo, Infection holds the package at 100 % of covered mutants.

Testing code that dispatches the events

An owner's test dispatches on a recording dispatcher and reads the events back:

$dispatcher = new Symfony\Component\EventDispatcher\EventDispatcher();
$events = [];
$dispatcher->addListener(PagePublished::class, static function (PagePublished $event) use (&$events): void {
    $events[] = $event;
});

// ... publish a page through the owner ...

self::assertSame('news:42', $events[0]->ownerId);
