测试 ssh 连接 [英] Testing ssh connection

问题描述

我的项目的一个重要部分是使用 ssh 登录远程服务器并对其上的文件做一些事情:

an important part of my project is to log in into remote server with ssh and do something with files on it:

Net::SSH.start(@host, @username, :password => @password) do |ssh|  
  ssh.exec!(rename_files_on_remote_server) 
end

如何测试?我想我可以打开本地 ssh 服务器并检查其上的文件名(也许它可能在我的 test/spec 目录中).或者也许有人可以为我指出更好的解决方案?

How to test it? I think I can have local ssh server on and check file names on it (maybe it could be in my test/spec directory). Or maybe someone could point me better solution?

推荐答案

我认为这足以测试您是否向 ssh 服务器发送了正确的命令.您的应用程序可能没有实现服务器 - 因此您必须相信服务器正常工作并经过测试.

I think it's enough to test that you're sending the correct commands to the ssh server. You're application presumably doesn't implement the server - so you have to trust that the server is correctly working and tested.

如果您确实实现了服务器，那么您需要对其进行测试，但就 SSH 而言，我会做一些这样的模拟(RSpec 2 语法):

If you do implement the server then you'd need to test that, but as far as the SSH stuff goes, i'd do some mocking like this (RSpec 2 syntax):

describe "SSH Access" do
  let (:ssh_connection) { mock("SSH Connection") }
  before (:each) do
    Net::SSH.stub(:start) { ssh_connection }
  end
  it "should send rename commands to the connection" do
    ssh_connection.should_receive(:exec!).ordered.with("expected command")
    ssh_connection.should_receive(:exec!).ordered.with("next expected command")
    SSHAccessClass.rename_files!
  end
end
