title: How to test emails within unit tests

Testing Email within Unit Tests

SilverStripe's test system has built-in support for testing emails sent using the Email class. If you are running a SapphireTest test, then it holds off actually sending the email, and instead lets you assert that an email was sent using this method.

:::php
public function MyMethod() {
	$e = new Email();
	$e->To = "someone@example.com";
	$e->Subject = "Hi there";
	$e->Body = "I just really wanted to email you and say hi.";
	$e->send();
}

To test that MyMethod sends the correct email, use the SapphireTest::assertEmailSent() method.

:::php
$this->assertEmailSent($to, $from, $subject, $body);

// to assert that the email is sent to the correct person
$this->assertEmailSent("someone@example.com", null, "/th.*e$/");

Each of the arguments ($to, $from, $subject and $body) can be either one of the following.

• A string: match exactly that string
• null/false: match anything
• A PERL regular expression (starting with '/')
