ruby-on-rails - 开始对 Ruby Rails 网站进行单元和功能测试的最佳方法是什么？

Question

我正在测试一个 Ruby Rails 网站，想开始进行单元和功能测试。

Answer 1

Cucumber和 RSpec值得一看。他们鼓励在 behaviour-driven 中进行测试，基于示例的样式。

RSpec 是一个用于单元级测试的库:

describe "hello_world"
  it "should say hello to the world" do
    # RSpec comes with its own mock-object framework built in,
    # though it lets you use others if you prefer
    world = mock("World", :population => 6e9)
    world.should_receive(:hello)
    hello_world(world)
  end
end

它对 Rails 有特殊的支持(例如，它可以单独测试模型、 View 和 Controller )并且可以替代 Rails 内置的测试机制。

Cucumber(以前称为 RSpec Story Runner)让您可以用(相当)简单的英语编写高级验收测试，您可以向客户展示(并同意)客户，然后运行它们:
