Trying to mock Store getLocale, getting “Method cannot be configured…”

Question

I have this Magento 2 unit test code:

    $storeInterfaceMockDe = $this->getMockBuilder(\Magento\Store\Model\Store::class)
        ->disableOriginalConstructor()
        ->setMethods(['getLocaleCode'])
        ->getMock();
    $storeInterfaceMockDe->expects($this->any())->method('getLocalCode')->willReturn('de_DE');

But PHPUnit throws:

Trying to configure method "getLocalCode" which cannot be configured because it does not exist, has not been specified, is final, or is static

But the core uses similar code.

What am I doing wrong?

Actually the method is a magic method, so it really does not exist -- but why does it work in the core code?

Answer 1

You have a typo in the method name. The mocked method is getLocaleCode (with an e in Locale), and the expectation is set for a method getLocalCode (without the e).

Small side note, somewhat unrelated to your question:
I don't like partial mocks, so I generally also add the existing methods to the mock if I have to configure magic methods via the builder:

->setMethods(array_merge(get_class_methods(Store::class), ['getLocaleCode']))
