Ruby on rails 理解RSpec故障

我在运行

rspec spec/

时遇到这些故障。失败的规范是通过脚手架自动生成的。我试图理解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，该应用程序似乎运行良好。

test.log

中未显示有关这些故障的任何信息。有没有其他地方我应该寻找线索来追踪这件事

$ rspec spec/
.....................F.F.

您是否也在使用simple\u form（或者甚至formtastic）？当我将脚手架表单从标准表单转换为简单表单（

form\u for（@user）

=>

simple\u-for（@user）

）时，我会遇到同样的错误

正如你所说，它仍然有效，所以我不确定它是否值得担心。我想你最好还是让Cucumber担心一下。莎拉·梅说：：-）

#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
