使用Rake运行Ruby单元测试

I was investigating using the Rake build tool to automate running unit tests. I searched the web, but all the examples were for using rails. I usually just write small command-line programs or simple Sinatra applications.

我正在研究使用Rake构建工具来自动运行单元测试。我在网上搜索过，但所有的例子都是使用rails。我通常只是编写小型命令行程序或简单的Sinatra应用程序。

So I came up with the following (probably bad) solution that just emulates what I would do on the command-line: (I just ran one unit test as an example.)

所以我提出了以下（可能是坏的）解决方案，它只是模仿我在命令行上会做的事情:(我只是以一个单元测试为例。）

desc 'Run unit tests'
task :test do
    sh 'ruby -I lib test/test_entry.rb'
end
task :default => :test

It works, but I can't help thinking there must be a better way, just writing require 'test/test_entry.rb' doesn't work. I get require problems, Ruby can't find the lib directory, where all the files are.

它有效，但我不禁想到必须有更好的方法，只需要写'test / test_entry.rb'就行了。我得到了问题，Ruby无法找到所有文件所在的lib目录。

Use Rake::TestTask http://rake.rubyforge.org/classes/Rake/TestTask.html . Put this into your Rake file and then run rake test:

使用Rake :: TestTask http://rake.rubyforge.org/classes/Rake/TestTask.html。把它放到你的Rake文件中，然后运行rake test：

require 'rake/testtask'

Rake::TestTask.new do |t|
  t.libs << "test"
  t.test_files = FileList['test/test*.rb']
  t.verbose = true
end

The problem is that your lib directory is not included into ruby's loading path. You can fix it like that:

问题是你的lib目录没有包含在ruby的加载路径中。你可以像这样解决它：

$:.unshift 'lib'
require 'test_entry'

or more reliable alternative that adds expanded path of lib directory to the loading path:

或者更可靠的替代方法，它将lib目录的扩展路径添加到加载路径：

$:.unshift File.expand_path(File.join(File.dirname(__FILE__), 'lib'))
require 'test_entry'

Btw, global variable $: has more verbose alias $LOAD_PATH.

顺便说一下，全局变量$：有更多详细的别名$ LOAD_PATH。
