为 Rails 2.3 和 Rspec 设置 Capybara

Question

我在使用 Rspec 1.3 的 rails 2.3.8 应用程序中设置 capybara (0.4.1.2) 时遇到了一些问题根据安装 capybara 说明，我插入了以下行：

require 'capybara/rspec' 

但是，这给了我一个缺少的常量错误。似乎它正在寻找一个未加载的类“RSpec”（我猜这是 RSpec 2 / Rails 3 的东西）。

那么如何让 Rspec 在 Rails 2.3 下识别水豚？我应该使用早期版本的 capy 吗？

Answer 1

Capybara 没有内置对 RSpec 1.x 的支持。但是，您可以使用 Steak 而不是滚动您自己的 RSpec 支持。

Answer 2

如果你只想做'请求规格'（如 railscasts 的“我如何测试”中定义的那样），似乎并不真的需要牛排。 另见：What does Steak add beyond just using Capybara and RSpec in Rails testing?

我刚刚在这里设置了rails 2.3 + rspec 1 + capybara(最新版本)，没有任何麻烦

你不能拥有require capybara/rspec，但它似乎所做的只是添加一些匹配器......但真正重要的是水豚及其 DSL 和验证东西

Capybara 适用于任何机架应用

在我的spec_helper.rb：

require 'capybara/rails'
include Capybara::DSL

就是这样 （只需点击 Capybara 的文档，它是 DSL，因为一些 rspec-capybara 匹配器可能会丢失，没有什么会阻塞，tho）

Answer 3

来自 Capybara 文档，

Note that Capybara’s built in RSpec support only works with RSpec 2.0 or later. You’ll need to roll your own for earlier versions of RSpec.
