了解RSpec失败

Question

我在运行rspec spec/时遇到了这些问题。失败的规范是使用脚手架自动生成的。我正在尝试理解RSpec，但我不知道从哪里开始寻找原因除了感觉感觉某些方法丢失了？！？然而，应用似乎工作正常。 test.log中没有关于这些失败的信息。还有其他地方我应该寻找提示来追踪这个吗？

$ rspec spec/

这是显然失败的规范（edit.html.haml_spec.rb）。它由rails g scaffold Clown name:string balloons:integer自动生成：

#spec/views/clowns/edit.html.haml_spec.rb
require 'spec_helper'

describe "clowns/edit.html.haml" do
  before(:each) do
    @clown = assign(:clown, stub_model(Clown,
      :name => "MyString",
      :balloons => 1
    ))
  end

  it "renders the edit clown form" do
    render

    # Run the generator again with the --webrat-matchers flag if you want to use webrat matchers
    assert_select "form", :action => clown_path(@clown), :method => "post" do
      assert_select "input#clown_name", :name => "clown[name]"
      assert_select "input#clown_balloons", :name => "clown[balloons]"
    end
  end
end

您是否也使用 simple_form （或者甚至 formtastic ）？当我将脚手架形式从标准形式转换为simple_form形式（form_for(@user) =＆gt; simple_form_for(@user)）时，我得到了同样的错误。

正如你所说，它仍然有效，所以我不确定它值得担心。我想你最好让黄瓜担心它。莎拉梅说view specs are a waste of time。 ： - ）
