开发宝石和测试 [英] Developing gems and testing

问题描述

我是开发Ruby gem的新手，但是我想尝试一下.

I am new to developing Ruby gems, but I thought I'd give it a try.

最近查看了Railscasts的最新剧集(http://railscasts.com/episodes/245-new-gem-with-bundler)，我正在使用Bundler来创建我的宝石.

Recently checking out the latest episode on Railscasts (http://railscasts.com/episodes/245-new-gem-with-bundler) I'm using Bundler to create my gem.

但是我对如何测试我的宝石一无所知.

However I'm kind of clueless on how to test my gem.

我可以先运行 rake install ，然后从 irb 要求它，但这对我来说似乎是一种缓慢的工作流程.

Sure I could run rake install and then require it from irb, but this seems like a kind of slow workflow for me.

我想做的是创建一个虚拟的Rails应用程序，并通过引用它的源代码来要求gem.这可能吗?我敢肯定我在某处读过它……

What I'd like to do is create a dummy Rails app and require the gem by referencing to it's source code. Is this possible? I'm sure I've read about it somewhere…

谢谢！

推荐答案

您可以在Rakefile中包含以下行:

You can include these lines in your Rakefile:

task :console do
  exec "irb -r mygem -I ./lib"
end

这将创建一个rake任务，以初始化一个新的irb会话并预加载您的库.现在，您要做的就是:

This will create a rake task to initialize a new irb session and preload your library. Now, all you have to do is:

$ rake console
