I'm trying to unit-test my controller (Yii framework).
/**
* @dataProvider provider
*/
public function testActionEdit_view_login($controller){
$user = new CWebUser;
$user->id = 978;
$identity = new UserIdentity('[email protected]', '123456');
$user->login($identity);
$controller->actionEdit();
$output = ob_get_contents();
assertContains('Add/Change Profile Picture:', $output);
assertContains('bio', $output);
assertContains('specialties', $output);
assertContains('change login', $output);
assertContains('New Password', $output);
}
When I do
$user->login($identity);
in order to login, I get the following error:
session_regenerate_id(): Cannot regenerate session id - headers already sent
I've already tried buffering the output by putting this at the beginning of the class:
public static function setUpBeforeClass(){
ob_start();
}
I also put ob_clean() in setUp() and ob_end_clean() in tearDownAfterClass().
Still I get the message that headers have already been sent. There are no spaces or newlines in the file, when I comment out the specific test method, it works perfectly. The login() seems to cause the problem.
Anyone got ideas how to prevent this / maybe unit-test the controller differently?
Thanks, MrB
Before your call to $user->login
, add the following code:
$mockSession = $this->getMock('CHttpSession', array('regenerateID'));
Yii::app()->setComponent('session', $mockSession);
This overwrites the regenerateID
method with a method that does nothing.
Adding ob_start()
to the bootstrap also works, but there is no output from PHPUnit until everything has completed.
With this method, you can still see the progress as it is happening.
I upgraded from Yii 1.1.7 to 1.1.10 and the regenerateID
method was added in 1.1.8 so I got this error today.
Got it. I had included some Yii files before the ob_start(), which seem to have printed the headers. Now I buffer that, too.
