无法继承正确的父 class，init 采用 1 个位置参数，但给出了 2 个

Question

我有基地class

class Environment(unittest.TestCase):
    def setUp(self):
        options_for_console_log = DesiredCapabilities.CHROME
        options_for_console_log['loggingPrefs'] = {'browser': 'ALL'}
        self.driver = webdriver.Chrome(desired_capabilities=options_for_console_log)
        self.driver.maximize_window()
        print('1', self.driver)

    def tearDown(self):
        driver = self.driver
        driver.close()

和一个class继承基数的

class StatusesCheckManual(Environment):
    def __init__(self):
        super(Environment).__init__()

    def test_1_add_materials(self):

        self.create_order = CreateOrder(self.driver)
        self.order_statuses = Order_manual_statuses(self.driver)
        self.order = Order(self.driver)


        self.order_id = self.create_order.create_fake_order()

        LoginAsAdmin(self.driver).login()

        self.order.go_to_order(self.order_id)
        status = self.order_statuses.change_to_addmat()
        self.assertEqual(status, 'Add Materials')

但我明白了

init() takes 1 positional argument but 2 were given

我如何需要 inerhit 基地 class？

Answer 1

由于您没有在此处覆盖 init() 方法中的任何内容，因此您没有必要将其包含在 StatusesCheckManual subclass.

如果您确实需要覆盖 init()，您也需要在环境中执行此操作，并确保包含相同的参数：

class StatusesCheckManual(Environment):
    def __init__(self, methodName='runTest'):
        super(StatusesCheckManual, self).__init__(methodName)

class Environment(unittest.TestCase):
    def __init__(self, methodName='runTest'):
        super(Environment, self).__init__(methodName)

（请注意 super 的第一个参数是当前 class，而不是父级）

无法继承正确的父 class，init 采用 1 个位置参数，但给出了 2 个

Cannot inheritance correct parent class, init takes 1 positional argument but 2 were given
