预期 "Object" 接收消息未按预期工作

Question

我有这个规格：

it 'makes a request to google if redis is empty' do
  fetch_cfm_data

  expect(GoogleCalendarApi::V1::Client).to receive(:get_cfm)
end

我已经调试了在我的测试过程中被调用的消息，并且 GoogleCalendarApi::V1::Client.get_cfm 肯定被调用了，因为我可以在测试运行期间窥探该方法的内部。为什么我的测试 return 失败了？

Failure/Error: expect(GoogleCalendarApi::V1::Client).to receive(:get_cfm)

       (GoogleCalendarApi::V1::Client (class)).get_cfm(*(any args))
           expected: 1 time with any arguments
           received: 0 times with any arguments

Answer 1

需要先设置期望值，然后调用被测方法：

  expect(GoogleCalendarApi::V1::Client).to receive(:get_cfm)
  fetch_cfm_data
