[MFTF] Eliminate AspectMock from ObjectExtensionUtilTest (Complex!)

[sivaschenko]

This task is tricky and requires investigation on the approach to mock static calls without Aspect Mock

Goal

codeception/aspect-mock library is still not compatible with PHP 8.0 at the time of the creation of this ticket.

To speed up Magento compatibility with new PHP versions we'd like to eliminate codeception/aspect-mock dependency from MFTF. This will make MFTF compatible with PHP 8.0 that is required for declaring the Magento core PHP 8 compatible as well.

In order to do this existing unit tests using AspectMock should be refactored to use PHPUnit instead.

Task

Eliminate AspectMock usage from dev/tests/unit/Magento/FunctionalTestFramework/Test/Util/ObjectExtensionUtilTest.php in https://github.com/magento/magento2-functional-testing-framework repository.

Example

Mocking an object using AspectMock (current):

        $mock = AspectMock::double(
            MockedClass::class,
            [
                'mockedMethodName' => 'methodReturnValue',
            ]
        )->make();

Mocking an object using PHPUnit (refactored code):

        $mock = $this->createMock(File::class);
        $file->expects($this->any())
            ->method('mockedMethodName')
            ->willReturn('methodReturnValue');
