现在我已经了解了TestUnit,RSpec,Capybara和MiniTest.我开始对什么是什么感到困惑.

这4个项目有什么区别？我知道Cucumber显然执行纯文本功能,我想这可以被认为是集成测试.

但现在我也看到最近版本的Cucumber需要MiniTest？ Cucumber只是一个位于测试框架之上的DSL吗？

我也知道RSpec有自己的语法糖来做断言,即“描述”块.似乎MiniTest也支持这种语法.

我知道Capybara用于查看生成的网页内容.

这是我的问题：

如果我正在创建一个新的Rails 3.2应用程序,我应该使用这些测试程序的组合？什么是额外有用的列表,解释这些宝石及其相关过程如何在适用的情况下相互补充,例如：

Cucumber is a DSL for driving BDD
Cucumber is for integration tests and is based on creating user stories that are customer-readable
It implements its tests behind the scenes via MiniTest
MiniTest is a new testing framework that comes with Ruby 1.9 and is very fast.
MiniTest is also used for unit testing,such as testing controllers and models
It does not yet have as many features as RSpec
Cucumber also uses Capybara to access DOM elements from a javascript-enabled browser simulator such as Selenium
When you test in Rails,you have the ability to do the following kinds of tests: controllers,views,models,and integration (MVC together)
Some people just do integration and model testing,because they feel that integration testing handles enough of the controller and view testing itself,and anything too complex can simply be moved up to the model

非常感谢您提供任何帮助,以便为我清除这些想法.
