Ruby 未定义的局部变量或方法“mock'；对于main:Object

我正在使用它进行测试

2.1.5 :047 > require 'mocha'
  => false 

AFAIK这意味着

摩卡

已经加载，应该可以了。无论如何，在模拟或存根时：

模拟是否应该在IRB中工作？

在我加入

Mocha:：API

之前，我也有同样的错误。这将使Mocha的方法适用于您的

对象

，

模块

，

类

类，并将遗漏的功能添加到您的irb会话中：

$ 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) >

$irb
欢迎来到IRB。您正在使用ruby 2.2.0p0（2014-12-25修订版49005）[x86_64-linux]。玩得开心；）
>>要求“摩卡/api”#=>正确
>>包括Mocha:：API#=>对象
>>模拟#=>#
>>存根#=>#
>>Object.expected:something#=>#

它也不起作用。无论如何，只给出代码示例是一种解释问题的糟糕方式。
