How to set a variable within a mock object

Is there any way to set a class level variable within a mock object?

I have the mock object set similar to this:

$stub = $this->getMock('SokmeClass', array('method'));
$stub->expects($this->once())
     ->method('method')
     ->with($this->equalTo($arg1));

Win the real class there is a variable that needs to be set for it to work properly. How can I set that variable within a mock object?

Here is what works for me:

$stub = $this->getMock('SomeClass');
$stub->myvar = "Value";

Don't know why this works but it seems to for me. If you put the __get magic method as one of the overridden methods e.g.

$mock = $this->getMock('Mail', array('__get'));

You can then you can successfully do

$mock->transport = 'smtp';

The idea of a stub is to replace a dependency with a test double offering the same method interface that (optionally) returns configured return values. This way, the SUT can work with the double like it was the dependency. If you need a specific return value from the stub, you just tell it what it should return, e.g.:

// Create a stub for the SomeClass class.
$stub = $this->getMock('SomeClass');

// Configure the stub.
$stub->expects($this->any())
     ->method('doSomething')
     ->will($this->returnArgument(0));

$stub->doSomething('foo'); // returns foo

See http://www.phpunit.de/manual/current/en/test-doubles.html
