Question

I have a doctrine class User which is of this hierarchy Doctrine_Record -> BaseUser -> User. In PHP symfony you are aware that you can access doctrine record using array accessor as well methods. Each class has @property and a method.

$user['mode'] == $user->getMode()

When I am writing PHPUnit test cases, I am unable to mock occurrences where array accessor method is used.

Here is sample code from unit test as well the actual code –

User.php

class User extends BaseUser {
public function clearInactiveUsers()
  {
    foreach ($this->users as $user) {
      if (!$user['mode']) {
        unset($this->users[array_search($user, $this->users)]);
        $user->delete();
      }
    }
    unset($user);
  }
}

This is the test for it

UserTest.php

public function testOnlyInactiveUsersAreRemoved()
  {
    $userGroup = new UserGroup();
    $user_1 = $this->getMock('User');
    $user_2 = $this->getMock('User');
    $user_1->expects($this->at(0))->method('__get')->with($this->equalTo('mode'))->will($this->returnValue(1));
    $user_2->expects($this->at(0))->method('__get')->with($this->equalTo('mode'))->will($this->returnValue(0));
    $userGroup->adduser($user_1);
    $userGroup->adduser($user_2);
    $userGroup->clearInactiveUsers();
    $this->assertCount(1, $userGroup->getUsers());
  }

I am trying to mock the occurrence $user['mode'] in the code. What I am doing wrong?

I have referenced following link and wrote above code.

You need to tell PHPUnit to mock the methods before setting their expectations. Also, you’re accessing mode via array access–not property access. Does BaseUser implement ArrayAccess? You should be mocking offsetGet instead of __get.

$user_1 = $this->getMock('User', array('offsetGet'));
$user_2 = $this->getMock('User', array('offsetGet'));
$user_1->expects($this->at(0))->method('offsetGet')->with($this->equalTo('mode'))->will($this->returnValue(1));
$user_2->expects($this->at(0))->method('offsetGet')->with($this->equalTo('mode'))->will($this->returnValue(0));
