Creating mock Objects in PHP unit
- by Mike
Hi,
I've searched but can't quite find what I'm looking for and the manual isn't much help in this respect. I'm fairly new to unit testing, so not sure if I'm on the right track at all. Anyway, onto the question. I have a class:
<?php
class testClass {
public function doSomething($array_of_stuff) {
return AnotherClass::returnRandomElement($array_of_stuff);
}
}
?>
Now, clearly I want the AnotherClass::returnRandomElement($array_of_stuff); to return the same thing every time. My question is, in my unit test, how do I mockup this object?
I've tried adding the AnotherClass to the top of the test file, but when I want to test AnotherClass I get the "Cannot redeclare class" error.
I think I understand factory classes, but I'm not sure how I would apply that in this instance. Would I need to write an entirely seperate AnotherClass class which contained test data and then use the Factory class to load that instead of the real AnotherClass? Or is using the Factory pattern just a red herring.
I tried this:
$RedirectUtils_stub = $this->getMockForAbstractClass('RedirectUtils');
$o1 = new stdClass();
$o1->id = 2;
$o1->test_id = 2;
$o1->weight = 60;
$o1->data = "http://www.google.com/?ffdfd=fdfdfdfd?route=1";
$RedirectUtils_stub->expects($this->any())
->method('chooseRandomRoot')
->will($this->returnValue($o1));
$RedirectUtils_stub->expects($this->any())
->method('decodeQueryString')
->will($this->returnValue(array()));
in the setUp() function, but these stubs are ignored and I can't work out whether it's something I'm doing wrong, or the way I'm accessing the AnotherClass methods.
Help! This is driving me nuts.
