  Assert nothing published
==========================

You can assert that nothing was published at all, using the `assertNothingPublished`:

         ```
use PHPUnit\Framework\TestCase;
use Junges\Kafka\Facades\Kafka;
use Junges\Kafka\Message\Message;

class MyTest extends TestCase
{
    public function testWithSpecificTopic()
    {
        Kafka::fake();

        if (false) {
            $producer = Kafka::publish('broker')
                ->onTopic('some-kafka-topic')
                ->withHeaders(['key' => 'value'])
                ->withBodyKey('key', 'value');

            $producer->send();
        }

        Kafka::assertNothingPublished();
    }
}
```
