我在运行时遇到这些故障rspec spec/。失败的规范是使用脚手架自动生成的。我试图了解 RSpec，但我不知道从哪里开始寻找原因，除了感觉缺少某种方法？！？然而，应用程序似乎运行良好。没有任何关于这些失败的内容出现在test.log. 我应该在另一个地方寻找线索来追踪它吗？

$ rspec spec/

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

#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

您是否也在使用simple_form（甚至可能是formtastic）？当我将脚手架表单从标准表单转换为 simple_form 表单（form_for(@user)=> simple_form_for(@user)）时，我得到了同样的错误。

正如您所说，它仍然有效，所以我不确定是否值得担心。我认为你最好让黄瓜担心它。Sarah Mei 说查看规格是浪费时间。:-)
