如何在 rspec 中验证退出值? [英] How can I validate exit value in rspec?

问题描述

我有一个有时会调用 exit(numeric_value) 的方法.

I have a method that will sometimes call exit(numeric_value).

rspec 是否可以验证调用方法时，进程是否以正确的值退出?

Is it possible for rspec to validate that when the method is invoked, the process is exiting with the correct value?

我看过这些其他帖子，但他们没有回答这个具体问题.

I have seen these other posts, but they do not answer this specific question.

推荐答案

给定示例 ruby​​ 代码:

Given sample ruby code:

def it_will_exit
  puts "before exit"
  exit(false)
  puts "never get here"
end

rspec 测试用例可以是:

rspec test case can be:

it "it must exit" do
  expect { it_will_exit }.raise_exception(SystemExit)
end

it "the exit value should be false" do
  begin
    it_will_exit
  rescue SystemExit=>e
    expect(e.status).to eq(1)
  end
end
