Test Laravel Event Broadcasting

This package lets you test if Laravel events has been broadcasted. This is useful for TDD and End-to-end testing.

Installation

1. Install the package via composer:

composer require GENL/laravel-broadcast-testing

2. Add the test broadcaster to the connections array in app/config/broadcasting.php.

'connections' => [
    ...
    'test' => [
        'driver' => 'test'
    ],
],

3. Set the default broadcaster for testing in the php element of phpunit.xml.

<php>
    ...
    <env name="BROADCAST_DRIVER" value="test"/>
</php>

4. Finally add the Genl\TestBroadcaster\CanTestBroadcasting trait to tests/TestCase.php.

use Genl\TestBroadcaster\CanTestBroadcasting;
abstract class TestCase extends BaseTestCase
{
    use CanTestBroadcasting;
}

Usage

This package adds the assertEventBroadcasted method to your testing.

/**
 * @test
 */
public function it_can_assert_when_an_event_is_broadcasted()
{
    event(new TestEvent());
    $this->assertEventWasBroadcast(TestEvent::class);
}

Futhermore it is also possible to test for how many times an even is broadcasted

/**
 * @test
 */
public function it_can_assert_if_an_event_was_broadcasted_a_given_amount_of_times()
{
    event(new TestEvent());
    $this->assertEventWasBroadcast(TestEvent::class, 1);

    event(new TestEvent());
    $this->assertEventWasBroadcast(TestEvent::class, 2);
}

/**
 * @test
 */
public function it_can_assert_if_an_event_was_broadcasted_a_given_amount_of_times()
{
    event(new TestEvent());
    $this->assertEventWasBroadcast(TestEvent::class, 1);

    event(new TestEvent());
    $this->assertEventWasBroadcast(TestEvent::class, 2);
}

The assertEventWasBroadcast method can also assert on which channels the event is broadcasted to. It can either take a single string, for a single channel, or an array of channel names.

/**
 * @test
 */
public function it_can_assert_if_an_event_was_broadcasted_on_multiple_channels()
{
    event(new TestEvent());

    // 
    $this->assertEventWasBroadcast(TestEvent::class, ['private-channel-name', 'private-another-channel-name']);

    try {
        $this->assertEventWasBroadcast(TestEvent::class, [
            'private-channel-name',
            'somethingelse-fake-channel',
        ]);
        $this->fail("assertEventBroadcasted asserted that an event was broadcasted on given channels when it wasn't");
    } catch (ExpectationFailedException $e) {
    }
}
