将CELERY_ALWAYS_EAGER设置为True会引发错误

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)

我对返回任何结果不感兴趣，重要的是在运行测试时同步执行函数，而不会引发错误。

测试时，我试图在设置文件中将CELERY_ALWAYS_EAGER设置为True:

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

我也试着在测试中设置它：

from django.conf import settings
settings.CELERY_ALWAYS_EAGER = True

这两次尝试都会使我的测试抛出错误（如果没有"延迟"，它可以正常工作）：

谢谢，Kev

Answer 1

我太笨了。我的CELERY_ROUTES中有一个"messages.tasks"。但没有文件/消息/任务.py.

您可以使用CeleryTestRunner进行测试。它将自动在ALWAYS_EAGER模式下运行测试
