@everzet : I think @mageekguy found a way to mock these class in atoum. Perhaps you could ask him for tips ;)

@jubianchi there's no clean way to mock this class. And i already know dirty one...

$fileObject = $this->getMock('SplFileObject', [], ['php://memory']);

Thank you for posting that solution! Just stumbled across this in Google while trying to mock the same object. You saved me a bunch of time I'm sure!

@nackjicholson thanks for that one!

You are the bomb @nackjicholson

For anyone who wants details about what is actually happening here;

SplFileObject will throw this error if you either;

1. Do not call the parent::__construct() at all.
   or
2. If you try to call other class methods (e.g. $this->callSomething()) BEFORE calling he parent::__construct(). The scope of the called method is irrelevant, so if you are calling a native SplFileObject/SplFileInfo method or a method in the scope of your superclass it will error. You can do other things before the parent::__construct() as long as they are not interacting with $this, parent:: or self:: (not sure about static methods. I assume the same goes for reading/writing properties but I haven't tested this. Ensure that anything you need to do is done pre-parent construct is done directly in the superclass construct and not abstracted to other methods if you can help it.
