Stub::update not working properly when changing method return value

Localisez le point d’entrée Stub::update dans le package Codeception Stub et reproduisez l’exemple PHP fourni. Comparez les résultats de la méthode et de l’attribut mis à jour, puis ajoutez des tests couvrant le comportement démontré afin que la méthode retourne C après la mise à jour, tandis que l’attribut continue de le faire.

Hello. The following snippet demonstrates the problem I'm having. Perhaps it's a bug?

class SomeCest{
	public function stubUpdate(UnitTester $I) {
		$object = new GenericClass();
		$actualGetValue1= $object->getValue();
		$actualAttr1= $object->attr;


		$Stub = Stub::make($object, [
			'getValue' => 'B',
			'attr' => 'B'
		]);
		$actualGetValue2 = $Stub->getValue();
		$actualAttr2= $Stub->attr;


		Stub::update($Stub, [
			'getValue' => "C",
			'attr' => "C"
		]);
		$actualGetValue3 = $Stub->getValue();
		$actualAttr3= $Stub->attr;


		$I->assertEquals('A', $actualAttr1); 	 	// ok
		$I->assertEquals('A', $actualGetValue1); 	// ok
		$I->assertEquals('B', $actualAttr2); 		// ok
		$I->assertEquals('B', $actualGetValue2); 	// ok
		$I->assertEquals("C", $actualAttr3); 		// ok
		$I->assertEquals("C", $actualGetValue3);	// => fails, uses previous value (B)
	}
}

class GenericClass {
	public $attr = 'A';
	public function getValue() {
		return 'A';
	}
}
