RSpec should_receive 宏，包含需要测试的内容的 id [英] RSpec should_receive macro that includes id of what needs to be tested

问题描述

我该如何编写它才能在不硬编码 1 的情况下通过.鸡和蛋.

How can I write this so it passes without hardcoding 1. Chicken and the egg.

@sender = Factory(:user)
@receiver = Factory(:user)

mailer = double
mailer.should_receive(:deliver)
Mailer.should_receive(:email).with(1, @sender.id, @receiver.id).and_return(mailer)

# This will create an object with id #1 to make this test pass
@object = Object.create(:sender => @sender, :receiver => @receiver)

推荐答案

这个怎么样?

Mailer.should_receive(:email).with(an_instance_of(Fixnum), @sender.id, @receiver.id).and_return(mailer)
