Question

我正在使用Mocha进行测试。

2.1.5 :047 > require 'mocha'
  => false

AFAIK意味着mocha已经加载，应该没问题。无论如何，当嘲笑或抄袭时：

模拟是否应该在IRB中起作用？

在我加入Mocha::API之前，我遇到了同样的错误。这将include适当的Mocha方法提供给您的Object，Module，Class类，并为您的irb会话添加错过的功能：

$ irb
Welcome to IRB. You are using ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]. Have fun ;)
>> require 'mocha/api' #=> true
>> include Mocha::API #=> Object
>> mock #=> #<Mock:0x2da1ce8>
>> stub #=> #<Mock:0x2d6a680>
>> Object.expects :something #=> #<Expectation:0x256e878 expected exactly once, not yet invoked: Object.something(any_parameters) >

undefined局部变量或方法`mock'for main：Object
