测试发送电子邮件不起作用

Question

我不明白为什么我运行测试时总是失败，AssertionError:0！=1 即使r的结果是1。在

class UserProfileTaskTest(TestCase):

    def test_send_email(self):
        subject = 'subject'
        body = 'body'
        from_email = 'from_email@test.com'
        recipient_list = ['recipient@test.com']

        r = send_mail(
            subject=subject,
            message=body,
            from_email=from_email,
            recipient_list=recipient_list
        )

        print(r)

        self.assertEqual(len(outbox), 1)

Answer 1

发件箱是一种特殊类型的属性，不能直接导入，但当你使用电子邮件后端发送电子邮件时邮箱将作为列表工作，并将电子邮件数据保存到发件箱列表。所以用下面的例子来判断是否发送了testmail。在

from django.core import mail
from django.test import TestCase

class UserProfileTaskTest(TestCase):
    def test_send_email(self):
        subject = 'subject'
        body = 'body'
        from_email = 'from_email@test.com'
        recipient_list = ['recipient@test.com']
        mail.send_mail(
            subject=subject,
            message=body,
            from_email=from_email,
            recipient_list=recipient_list
        )
        self.assertEqual(len(mail.outbox), 1)

当您运行上面的代码时，您有初始的mail.outbox = []

但在发送电子邮件之后，它将EmailMessage实例保存在列表中。在
