Write test case to verify email has sent or not.

How can I verify email has sent or not in laravel test cases?

Here is the email sending code

 Mail::send('front.mail.contact-us-mail', $data, function ($message) use ($data, $resume) //Send Mail to admin
                {
                    $message->to($data['email'])->subject('New Inquiry');
                    if ($resume) {
                        $message->attach(Storage::disk('s3')->url($resume));
                    }
                });
