如何解决PyTest 案例 1：将以下 UnitTest 代码转换为 PyTest：

如何将以下 unitest 代码转换为 pytest 代码

class ModelTests(TestCase):
def test_create_user_with_email_successful(self):
    """Test creating a new user with an email is successful"""
    email = "[e-mail]"
    password = "Password123"
    user = get_user_model().objects.create_user(email=email,password=password)

    self.assertEqual(user.email,email)
    self.assertTrue(user.check_password(password))

def test_new_user_email_normalized(self):
    """normalize Email"""
    email = "[e-mail]"
    password = "Password123"
    user = get_user_model().objects.create_user(email=email,password=password)
    self.assertEqual(user.email,email.lower())

def test_new_user_invalid_email(self):
    """Creating user with no email fails"""
    with self.assertRaises(ValueError):
        get_user_model().objects.create_user(None,"test123")

查询：

• 我已将以下测试写入 pytest 但有问题 test_new_user_invalid_email，如何改正？

• 由于我是编写 pytest 的新手，所以我也是 test_create_user_with_email_successful 和 test_new_user_email_normalized 写对了吗？

def test_create_user_with_email_successful(client) -> None:
    email = "[e-mail]"
    password = "Password123"
    user = get_user_model().objects.create_user(email=email,password=password)    
    assert user.email == email
    assert user.check_password(password)

def test_new_user_email_normalized(self):
    """normalize Email"""
    email = "[e-mail]"
    password = "Password123"
    user = get_user_model().objects.create_user(email=email,password=password)
    assert user.email == email.lower()


def test_new_user_invalid_email(self):
 """Creating user with no email fails"""
    with pytest.raises(ValueError) as e:
        get_user_model().objects.create_user(None,"test123")

解决方法

对我来说看起来很结实！您可能不需要 pytest.raises 中的 as e 除非您想对异常进行断言

顺便说一下，有一些 pip 包可以帮助您自动执行此操作。
