Magic methods on parent class not detected and MethodNotFoundException thrown

[dsnopek]

I'm writing some code which generates word documents using PhpWord, and I want to unit test that the right API calls are made on the PhpWord APIs.

The problem is that PhpWord has a class \PhpOffice\PhpWord\Element\AbstractContainer which has some magic methods via __call() and is the parent of several other classes, for example, \PhpOffice\PhpWord\Element\Section. The magic methods on AbstractContainer are correctly documented using @method and mocking these methods right on AbstractContainer works as expected, but doesn't when mocking any of its child classes like Section.

So, for example, I want to use code like this in my PHPUnit tests:

$section = $this->prophesize(\PhpOffice\PhpWord\Element\Section::class);
// One of the magic methods from parent. Throws exception!
$section->addTextRun()->shouldBeCalled();

... but this throws MethodNotFoundException:

Prophecy\Exception\Doubler\MethodNotFoundException: Method `Double\PhpOffice\PhpWord\Element\Section\P1::addTextRun()` is not defined.

... however, doing the same on AbstractContainer works fine:

// Mocking parent directly:
$section = $this->prophesize(\PhpOffice\PhpWord\Element\AbstractContainer::class);
// One of the magic methods from class itself. Works fine!
$section->addTextRun()->shouldBeCalled();

So, whatever code in Prophecy that's finding magic methods via @method is only working when directly mocking a class, not when mocking a child class.

Unfortunately, in my case, I need to mock both methods from the parent and the class itself, otherwise, maybe I could have just mocked parent.
