英文:
Abstract class and abastract Unitest
问题
以下是您要翻译的内容：
class Vehicule(ABC):wheel = Noneroof = Nonedef drive():use wheel and roof, blabla...class Car(Vehicule):wheel = 4roof = Trueclass Bike(Vehicule):wheel = 2roof = False
class TestVehicule(ABC, TestCase):wheel = Noneroof = Nonefactory = Nonedef test_how_many_wheel(self):self.assertEqual(factory.wheel, self.wheel)def test_is_roof(self):self.assertEqual(factory.roof, self.roof)class TestCar(TestVehicule)wheel = 4roof = Truefactory = CarFactoryclass TestBike(TestVehicule)wheel = 2roof = Falsefactory = BikeFactory
目标是在TestVehicule中编写测试，并在其他类中继承并更改变量，使用子变量执行所有测试。
英文:
I use Django Rest Framework and I wrote something like this:
class Vehicule(ABC):wheel = Noneroof = Nonedef drive():use wheel and roof, blabla...class Car(Vehicule):wheel = 4roof = Trueclass Bike(Vehicule):wheel = 2roof = False
It's working good and I want to write unitest with it.I want to write someting similar:
class TestVehicule(ABC, TestCase):wheel = Noneroof = Nonefactory = Nonedef test_how_many_wheel(self):self.assertEqual(factory.wheel, self.wheel)def test_is_roof(self):self.assertEqual(factory.roof, self.roof)class TestCar(TestVehicule)wheel = 4roof = Truefactory = CarFactoryclass TestBike(TestVehicule)wheel = 2roof = Falsefactory = BikeFactory
The goal is to write tests in TestVehicule and inherit in others class change variable and do all the tests with the child variable

最简单的解决办法是仅为您的非抽象类继承TestCase：
class TestVehicle(ABC):...class TestCar(TestVehicle, unittest.TestCase):...class TestBike(TestVehicle, unittest.TestCase):...
从技术上讲，如果您只希望unittest忽略它的用例，那么您的TestVehicle甚至不需要是抽象的。
英文:
The easiest way around the problem would be to only inherit TestCase for your non-abstract classes:
class TestVehicle(ABC):...class TestCar(TestVehicle, unittest.TestCase):...class TestBike(TestVehiule, unittest.TestCase):...
Technically, your TestVehicle doesn't even need to be abstract at this point, if all you want is for unittest to ignore its cases.
