“它"是什么意思RSpec 中的关键字 do? [英] what does the "it" keyword do in RSpec?

问题描述

我正在关注 rails3tutorial 并且在进行如下测试时我不明白it"关键字的含义:

I'm following the rails3tutorial and I don't understand the meaning of the "it" keyword when doing some testing as follows:

require 'spec_helper'

describe UsersController do
  render_views

  describe "GET 'new'" do
    it "should be successful" do
      get 'new'
      response.should be_success
    end

    it "should have the right title" do
      get 'new'
      response.should have_selector("title", :content => "Sign up")
    end
  end
end

推荐答案

它不是 Ruby 关键字，而是 Rspec 框架的一部分.

It's not a Ruby keyword, it's part of the Rspec framework.

it 包含说明行为方面的代码示例定义.它由两个主要部分组成:描述字符串和代码示例，在 do/end 块中.

it contains the code examples that illustrate the facet of behavior being defined. It is comprised of two main parts: the description string and the code example, in the do/end block.
