Easily Test Email with MailThief

MailThief is a new package by Tighten Co. that provides a fake mailer for your Laravel application. This makes it easy to test email without actually sending any.

To better explain how this package works take a look at the following example from the project.

First, pretend you have a registration route that sends the user a welcome email:

Route::post('register', function () {
// <snip> Validation, create account, etc. </snip>
Mail::send('emails.welcome', [], function ($m) {
$email = request('email');
$m->subject('Welcome to my app!');
// <snip> Return response </snip>

Typically testing this would be pretty difficult, but with MailThief it’s simple:

use MailThief\Facades\MailThief;
class RegistrationTest extends TestCase
public function test_new_users_are_sent_a_welcome_email()
// Block and intercept outgoing mail, important!
$this->post('register', [
'name' => 'John Doe',
'email' => 'john@example.com',
'password' => 'secret',
// Check that an email was sent to this email address
// BCC addresses are included too
// Make sure the email has the correct subject
$this->assertEquals('Welcome to my app!', MailThief::lastMessage()->subject);
// Make sure the email was sent from the correct address
// (`from` can be a list, so we return it as a collection)
$this->assertEquals('noreply@example.com', MailThief::lastMessage()->from->first());

You can grab the package from Github and if you’d like to learn more about the thought process behind building MailThief check out this post and video by Adam Wathan.
