Question

我的代码中有一些异步调用。像这样：

send_message_to_install.delay(install, alert.message, badge, code,
                            campaign=alert.campaign, **kwargs)

我对获取任何结果不感兴趣，在运行测试时同步执行该函数非常重要 - 不会抛出错误。

测试时，我尝试将设置文件中的CELERY_ALWAYS_EAGER设置为True：

if "test" in sys.argv:
    CELERY_ALWAYS_EAGER = True

我也尝试在测试中设置它：

from django.conf import settings
settings.CELERY_ALWAYS_EAGER = True

两次尝试都会让我的测试抛出错误（没有“.delay”它可以正常工作）：

ImportError: No module named tasks

谢谢，Kev

Answer 1

愚蠢的我。我的CELERY_ROUTES中有一个'messages.tasks'。但没有文件/messages/tasks.py。

Answer 2

您可以使用CeleryTestRunner进行测试。它将自动以ALWAYS_EAGER模式运行您的测试

将CELERY_ALWAYS_EAGER设置为True会引发错误
