我有Mailer
看起来像这样:
class EventMailer < BaseMailer
def event_added(user_id, event_id)
# do stuff and email user about the event
end
end
我在EventMailer
类中调用此Event
:
class Event < Task
def notify_by_email(user)
EmailLog.send_once(user.id, id) do
EventMailer.delay(queue: 'mailer').event_added(user.id, id)
end
end
end
其中EmailLog
是记录已发送电子邮件的类。 Sidekiq添加了.delay
。
但是当我尝试测试每个事件和用户只调用一次#notify_by_email
时,我的规范就失败了:
1) Event#notify_by_email only sends once per user
Failure/Error: expect(EventMailer).to receive(:event_added).once
(<EventMailer (class)>).event_added(any args)
expected: 1 time with any arguments
received: 0 times with any arguments
规范如下:
let(:owner) { User.make! }
let(:product) { Product.make! }
let(:event) { Task.make!(user: owner, product: product) }
describe '#notify_by_email' do
before do
EventMailer.stub(:delay).and_return(EventMailer)
end
it 'only sends once per user' do
event.notify_by_email(owner)
event.notify_by_email(owner)
expect(EventMailer).to receive(:event_added).once
end
end
有关此规范失败原因以及如何解决此问题的任何见解?奇怪的是,如果我在传递给puts
的块中放置EmailLog.send_once
语句,它只打印一次,规范仍会报告未调用EventMailer.event_added
。

您的期望应在之前宣布您正在测试的代码。使用expect(...).to receive(...)
基本上意味着&#34;此消息应在现在和本规范结束之间收到&#34;。因为期望是规范的最后一行,所以它失败了。
尝试之前移动它,你应该好好去:
it 'only sends once per user' do
expect(EventMailer).to receive(:event_added).once
event.notify_by_email(owner)
event.notify_by_email(owner)
end
