PHPUnit Mock an object's properties

Question

I'm looking for a way to mock an object and populate its properties. Here's an example of a method who uses a property of another object:

class MyClass {      private $_object;      public function methodUnderTest($object) {         $this->_object = $object;         return $this->_object->property     } } 

To Unit Test this method I should create a mock of $object with the getMockBuilder() method from PHPUnit. But I can't find a way to mock the properties of the $object, just the methods.

Answer 1

To add properties to a mocked object, you just set them as you'd normally do with an object:

$mock = $this->getMockBuilder('MyClass')              ->disableOriginalConstructor()              ->getMock();  $mock->property = 'some_value'; 

$mock->property will now return 'some_value'

Thanks to akond

P.s. for my project, this doesn't work with some classes, and when I try to call $mock->property it just returns NULL

Answer 2

If you have classes with magic methods you can use:

$mock->method('__get')->with('property')->willReturn('value');
