Usage

The Behat Mail Extension will automatically clear messages from the inbox when runing scenarios tagged with @mail

Feature: App Registration
  In order to join the site
  As a guest
  I want to register for an account

  @mail
  Scenario: Register an account
    Given I am a guest
    When I register for an account
    Then I should receive a welcome email
    

Access the mail property from your feature context to test any emails sent.

    /**
     * @Then I should receive a welcome email
     */
    public function iShouldReceiveAWelcomeEmail()
    {
        $message = $this->mail->getLatestMessage();

        PHPUnit_Framework_Assert::assertEquals('Welcome!', $message->subject());
        PHPUnit_Framework_Assert::assertContains('Please confirm your account', $message->plainText());
    }

The mail driver will return a message object with the following API:

• to()
