Python 是否可以为所有LiveServerTestCases登录一次？

我想这样做：

class TestSuite(LiveServerTestCase):

    @classmethod
    def setUp(self):
        self.driver = webdriver.Chrome()
        
        # Login User
        self.driver.get(self.live_server_url + '/somesite/login/')
        self.driver.find_element(By.ID, "username").click()
        self.driver.find_element(By.ID, "username").send_keys("foo")
        self.driver.find_element(By.ID, "password").click()
        self.driver.find_element(By.ID, "password").send_keys("bar")
        self.driver.find_element(By.ID, "login_button").click()
        # Redirects to home page
    
    @classmethod
    def tearDown(self):
        self.driver.quit()

    def test_foo(self):
        # Do some clicking with already logged in user from home page

    def test_bar(self):
        # Do some clicking with already logged in user from home page

我只是觉得在每个测试用例上调用setUp（）效率很低

非常感谢您的帮助……

因此，请将

安装程序

从

TestSuite

移动到

LiveServerTestCase
类
我讨厌回答我自己的问题。。。但多亏了奥利·卡恩的提示——扩展
LiveServerTestCase
，我才让它工作起来

步骤：

class TestSuite(LiveServerTestCase):

    @classmethod
    def setUpClass(cls):
        super(TestSuite, cls).setUpClass()

        cls.driver = webdriver.Chrome()
        
        # Login User
        cls.driver.get(cls.live_server_url + '/somesite/login/')
        cls.driver.find_element(By.ID, "username").click()
        cls.driver.find_element(By.ID, "username").send_keys("foo")
        cls.driver.find_element(By.ID, "password").click()
        cls.driver.find_element(By.ID, "password").send_keys("bar")
        cls.driver.find_element(By.ID, "login_button").click()
        # Redirects to home page
    
    @classmethod
    def tearDownClass(cls):
        cls.driver.quit()
        super(TestSuite, cls).tearDownClass()

    def test_foo(self):
        # Do some clicking with already logged in user from home page

    def test_bar(self):
        # Do some clicking with already logged in user from home page


使用
setUpClass
/
tearDownClass
（而不是
setUp
/
tearDown
）
将
setUpClass
/
tearDownClass
声明为
@classmethods
（如果使用更多装饰器，请将
@classmethod
放在第一位）
使用
super（）
扩展
LiveServerTestCase
对于
@classmethod
，使用
cls
而不是
self
，以符合PEP8

完整代码：

class TestSuite(LiveServerTestCase):

    @classmethod
    def setUpClass(cls):
        super(TestSuite, cls).setUpClass()

        cls.driver = webdriver.Chrome()
        
        # Login User
        cls.driver.get(cls.live_server_url + '/somesite/login/')
        cls.driver.find_element(By.ID, "username").click()
        cls.driver.find_element(By.ID, "username").send_keys("foo")
        cls.driver.find_element(By.ID, "password").click()
        cls.driver.find_element(By.ID, "password").send_keys("bar")
        cls.driver.find_element(By.ID, "login_button").click()
        # Redirects to home page
    
    @classmethod
    def tearDownClass(cls):
        cls.driver.quit()
        super(TestSuite, cls).tearDownClass()

    def test_foo(self):
        # Do some clicking with already logged in user from home page

    def test_bar(self):
        # Do some clicking with already logged in user from home page

为了改进答案，请解释一下解决问题的原因谢谢@olli_kahn提供的意见。我不想弄乱第三方模块，但如果我理解正确，可以通过扩展
LiveServerTestCase
；它应该会起作用。那么在这种情况下，
super（）
会起作用吗？如果是，我将如何实施？
