ruby-on-rails – 如何测试不是模型或控制器的代码

我在一个文件中定义了一个类,我的Rails项目的lib目录将实现一堆实用函数作为类方法.我想使用Test :: Unit编写针对这些方法的测试,并将它们作为项目常规测试例程的一部分运行.

我试着在测试目录的顶层粘贴一个文件…

require 'test_helper'

class UtilsTest < ActiveSupport::TestCase
  should 'be true' do
    assert false
  end
end

……但那没用.测试没有运行.

测试代码的正常方法是什么,而不是Rails的常规部分之一？

您可以将它们放在您的单位目录中,而不会出现任

我的图书馆：

[ cpm juno ~/apps/feedback ] cat lib/my_library.rb
class MyLib
  def look_at_me
    puts "I DO WEIRD STUFF"
  end
end

我的测试：

[ cpm juno ~/apps/feedback ] cat test/unit/fake_test.rb
require 'test_helper'

class FakeTest < ActiveSupport::TestCase
  # Replace this with your real tests.
  def test_truth
    require 'my_library'

    puts "RUNNING THIS NOW"
    MyLib.new.look_at_me
    assert true
  end
end

运行它：

[ cpm juno ~/apps/feedback ] rake test:units
(in /home/cpm/apps/feedback)
/usr/bin/ruby1.8 -Ilib:test "/usr/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake/rake_test_loader.rb" "test/unit/fake_test.rb"
Loaded suite /usr/lib/ruby/gems/1.8/gems/rake-0.8.3/lib/rake/rake_test_loader

只要它在_test.rb中结束,就应该把它拿起来.
