让Rspec支持中文

首先是让描述支持中文�Q�比如这��P��

# author: Percival  date: 12/06/09
# Have a good day!

require 'clazz'

describe Clazz do
  before(:each) do
    @clazz = Clazz.new
  end

  it "必须能够存储和设�|�类�?/span>" do

  end

  it "必须��它实现的接口存储在一个集合里" do

  end

  it "必须有一个集合用来存储需要导入的�c?/span>" do

  end

  it "必须对外提供拥有的所有方法接�?/span>" do

  end

  it "必须能够从一个文件中导入�c�M��?/span>" do

  end

end

需要修�?lib/spec/example/example_proxy.rb为：

require 'iconv' #让describe支持中文 ——Percival

module Spec
  module Example
    # Lightweight proxy for an example. This is the object that is passed to
    # example-related methods in Spec::Runner::Formatter::BaseFormatter
    class ExampleProxy

      def initialize(description=nil, options={}, location=nil) # :nodoc:
        #让describe支持中文 ——Percival
        description = Iconv.iconv("GBK","UTF-8",description)
        @description, @options, @location = description, options, location
      end

      # Optional hash passed to the example declaration
      attr_reader :options

      # This is the docstring passed to the it() method or any
      # of its aliases
      attr_reader :description

      # The file and line number at which the represented example
      # was declared. This is extracted from caller, and is therefore
      # formatted as an individual line in a backtrace.
      attr_reader :location

      # Deprecated - use location()
      def backtrace
        Spec.deprecate("ExampleProxy#backtrace","ExampleProxy#location")
        location
      end

      # Convenience method for example group - updates the value of
      # description and returns self.
      def update(description) # :nodoc:
        @description = description
        self
      end

      def ==(other) # :nodoc:
        (other.description == description) & (other.location == location)
      end
    end
  end
end

然后让should和should_not支持中文�Q�修改lib\spec\expectations\handler.rb:

require 'iconv'

module Spec
  module Expectations
    class InvalidMatcherError < ArgumentError; end

    class PositiveExpectationHandler
      def self.handle_matcher(actual, matcher, message=nil, &block)
        #让should支持中文
        if(actual.instance_of? String)
          actual = Iconv.iconv("UTF-8","GBK",actual).first
        end
        ::Spec::Matchers.last_should = :should
        ::Spec::Matchers.last_matcher = matcher
        return ::Spec::Matchers::PositiveOperatorMatcher.new(actual) if matcher.nil?

        match = matcher.matches?(actual, &block)
        return match if match

        message ||= matcher.respond_to?(:failure_message_for_should) ?
                    matcher.failure_message_for_should :
                    matcher.failure_message

        if matcher.respond_to?(:diffable?) && matcher.diffable?
          ::Spec::Expectations.fail_with message, matcher.expected.first, matcher.actual
        else
          ::Spec::Expectations.fail_with message
        end
      end
    end

    class NegativeExpectationHandler
      def self.handle_matcher(actual, matcher, message=nil, &block)
        #让should支持中文
        if(actual.instance_of? String)
          actual = Iconv.iconv("UTF-8","GBK",actual).first
        end
        ::Spec::Matchers.last_should = :should_not
        ::Spec::Matchers.last_matcher = matcher
        return ::Spec::Matchers::NegativeOperatorMatcher.new(actual) if matcher.nil?

        match = matcher.respond_to?(:does_not_match?) ?
                !matcher.does_not_match?(actual, &block) :
                matcher.matches?(actual, &block)
        return match unless match

        message ||= matcher.respond_to?(:failure_message_for_should_not) ?
                    matcher.failure_message_for_should_not :
                    matcher.negative_failure_message

        if matcher.respond_to?(:diffable?) && matcher.diffable?
          ::Spec::Expectations.fail_with message, matcher.expected.first, matcher.actual
        else
          ::Spec::Expectations.fail_with message
        end
      end
    end
  end
end

暂时我只用到�q�些元素�Q�可能还不全面，有遇到问题的再加上�?br />
