PHPUnit - creating Mock objects to act as stubs for properties

Question

I\'m trying to configure a Mock object in PHPunit to return values for different properties (that are accessed using the __get function)

Example:

Answer 1

I haven't tried mocking __get yet, but maybe this will work:

// getMock() is deprecated
// $mockObject = $this->getMock("OrigionalObject");
$mockObject = $this->createMock("OrigionalObject");

$mockObject->expects($this->at(0))
    ->method('__get')
    ->with($this->equalTo('ParameterA'))
    ->will($this->returnValue('ValueA'));

$mockObject->expects($this->at(1))
    ->method('__get')
    ->with($this->equalTo('ParameterB'))
    ->will($this->returnValue('ValueB'));

I've already used $this->at() in a test and it works (but isn't an optimal solution). I got it from this tread:

How can I get PHPUnit MockObjects to return different values based on a parameter?

Answer 2

This should work:

class Test extends \PHPUnit_Framework_TestCase {
...
    function testSomething() {
         $mockObject = $this->getMock("OrigionalObject");

         $mockObject
              ->expects( $this->any() )
              ->method('__get')
              ->will( $this->returnCallback('myMockGetter'));
         ...
     }
...
}

function myMockGetter( $classPropertyName ) {
    switch( $classPropertyName ) {
        case 'ParameterA':
            return 'ValueA';

        case 'ParameterB':
            return 'ValueB';
    }
}
... ...
