+# Queue Jobs
+
+Any `Sync` queue jobs are automatically run at the end of each test. Essentially the equivilant of,
+
+```php
+it('runs queues', function() {
+  mock(UpdateSearchIndex::class)
+    ->shouldReceive('execute')
+    ->once();
+
+  // Act and perform your test
+  Entry::factory()->create();
+
+  // This is run implicitely for you, as the very last step
+  // Craft::$app->queue->run();
+});
+```
+
+This test confirms that when an entry is created the `UpdateSearchIndex` job is run. You could just as easily test that a custom action or custom listener is run when an entry matching certain conditions is run.
