抱歉,如果之前有人问过这个问题。
一个简单的类:
class AskSO
def initialize( filehandle )
@filehandle = filehandle
end
def library_start
@filehandle << '<plist version="1.0">'
end
end
使用 Flex 模拟的简单单元测试
require 'rubygems'
require 'flexmock/test_unit'
require 'AskSO'
require 'test/unit'
class AskSOTest < Test::Unit::TestCase
def setup
@filehandle = flexmock( "filehandle", "<<" => "" )
end
def test_library_start
@filehandle.should_receive( "<<" ).with( '<plist version="1.0">' ).once
@AskSOInstance = AskSO.new( @filehandle )
@AskSOInstance.library_start
end
end
当我运行它时,ruby AskSO-test.rb
我得到
1) Failure:
test_library_start(AskSOTest)

我究竟做错了什么?提前致谢
