我已经定义了一个自定义错误,但如果我测试是否引发了自定义错误,则会失败.

我的models.py:

class CustomError(Exception):
    """
    This exception is my custom error
    """

class Company(models.Model):
    name = models.CharField(max_length=200)

    def test_error(self):
    raise CustomError('hello')

在我的tests.py中:

import unittest
from myapp.models import Company,Customer,Employee,Location,Product,ProductCategory,AllreadyPayedError,CustomError

class CompanyTestCase(unittest.TestCase):
    def setUp(self):
        self.company = Company.objects.create(name="lizto")

    def test2(self):
        self.assertRaises(CustomError, self.company.test_error)

此输出的测试失败:

======================================================================
ERROR: test2 (myapp.api.tests.CompanyTestCase)
