Rspec 测试（无法判断某行代码是否被执行）

Question

我尝试在 rspec 中测试此方法：

def resend_if_failed
  ResendWorker.new(self).resend_message
end

如何测试 ResendWorker.new(self).resend_message 是否已执行？

Answer 1

如果您的规范中有实例，您可以这样做：

expect(instance).to receive(:resend_if_failed)
instance.resend_if_failed

显然我猜resend_if_failed是由另一种方法触发的。

然后如有必要，单独测试 resend_if_failed 行为。

Answer 2

worker = double
allow(ResendWorker).to receive(:new).and_return(worker)
expect(worker).to receive(:resend_message)

instance.resend_if_failed

Rspec testing (can't tell whether a certain line of code is getting executed)
