在运行RSpec测试时启动irb以进行调试？

Question

如何在我的rspec测试运行期间启动irb？

基本上我希望能够玩各种各样的东西,然后我的rspec测试运行在程序的相应实例上.我能够在程序的常规运行时成功执行此操作,但是当我尝试在rspec测试的运行时期间启动irb时遇到问题.

传统运行时

test.rb

#!/usr/bin/env ruby
require 'irb'

puts 'hello world'
IRB.start
puts 'goodbye world'

运行

$ ./test.rb 
hello world
1.9.3-p194 :001 > puts 'yo'
yo
 => nil 
1.9.3-p194 :002 > exit
goodbye world

rspec运行时

test_spec.rb

require 'spec_helper'
require 'irb'

describe "irb" do
  it "should print 'hello world', launch irb, upon exiting irb print 'goodbye world'" do
    puts 'hello world'
    IRB.start
    puts 'goodbye world'
  end
end

运行

$ rake spec
/Users/username/.rvm/rubies/ruby-1.9.3-p194/bin/ruby -S rspec ./spec/test_spec.rb
Run options: include {:focus=>true}

hello world
1.9.3p194 :001 > require 'spec_helper'
 => false
1.9.3p194 :002 > require 'irb'
 => false
1.9.3p194 :003 >
1.9.3p194 :004 >   describe "irb" do
1.9.3p194 :005 >       it "should print 'hello world', launch irb, upon exiting irb print 'goodbye world'" do
1.9.3p194 :006 >           puts 'hello world'
1.9.3p194 :007?>         IRB.start
1.9.3p194 :008?>         puts 'goodbye world'
1.9.3p194 :009?>       end
1.9.3p194 :010?>   end1.9.3p194 :010?>
 => RSpec::Core::ExampleGroup::Nested_2
1.9.3p194 :010 >
goodbye world

使用撬.

简单,快速,语法高亮.安装完成后,您只需要写:

binding.pry

在您的代码中停止执行并显示开发人员调试控制台

在你爱上撬之后,还有一个名为'pry-nav'的有用宝石
