Question

对不起下面的代码呕吐，但我真的需要第二眼看到这个问题。感谢您的时间和帮助！我知道这是一个虚构的树屋应用程序的一个小问题，但是当我运行bin / rake时它让我感到窒息。如果有人有任何想法，请告诉我。谢谢！

 1) Adding todo items is successful with valid content
 Failure/Error: within("ul.todo_items") do
 Capybara::ElementNotFound:
   Unable to find css "ul.todo_items"
 # ./spec/features/todo_items/create_spec.rb:14:in `block (2 levels) in <top (required)>'

  2) todo_lists/index renders a list of todo_lists
 Failure/Error: assert_select "tr>td", :text => "Title".to_s, :count => 2
 Minitest::Assertion:

    Expected: 2
   Actual: 0
  # ./spec/views/todo_lists/index.html.erb_spec.rb:20:in `block (2 levels) in <top (required)>'

  3) Viewing todo items displays item content when a todo list has items
  Failure/Error: expect(page.all("ul.todo_items li").size).to eq(2)

   expected: 2

  4) Viewing todo items displays the title of the todo list

这是我的：app / views / todo_lists / index.html.erb

<h1>Todo Lists</h1>


<% @todo_lists.each do |todo_list| %>

有不同的问题，我将逐步完成它们

1) Adding todo items is successful with valid content
 Failure/Error: within("ul.todo_items") do
 Capybara::ElementNotFound:
   Unable to find css "ul.todo_items"
 # ./spec/features/todo_items/create_spec.rb:14:in `block (2 levels) in <top (required)>'

显然，CSS类在视图中发生了变化。您应该在规范中反映出来并将todo_items更改为functions。

  2) todo_lists/index renders a list of todo_lists
 Failure/Error: assert_select "tr>td", :text => "Title".to_s, :count => 2
 Minitest::Assertion:
    Expected exactly 2 elements matching "tr > td", found 0..
    Expected: 2
   Actual: 0
  # ./spec/views/todo_lists/index.html.erb_spec.rb:20:in `block (2 levels) in <top (required)>'

todo项目可能在前一段时间在一张桌子上，现在它只是一个<div class="todo_list">。您应该在规范中匹配：

  it "renders a list of todo_lists" do
    render
    # Run the generator again with the --webrat flag if you want to use webrat matchers
     assert_select "div.todo_list", :text => "Title".to_s, :count => 2
     assert_select "div.todo_list", :text => "MyText".to_s, :count => 2
  end

  3) Viewing todo items displays item content when a todo list has items
  Failure/Error: expect(page.all("ul.todo_items li").size).to eq(2)

   expected: 2
        got: 0

   (compared using ==)
 # ./spec/features/todo_items/index_spec.rb:25:in `block (2 levels) in <top (required)>'

同样的问题，与div.todo_list匹配，因为ul.todo_items不存在：

it "is successful with valid content" do
     visit_todo_list(todo_list)
     click_link "New Todo Item"
     fill_in "Content", with: "Milk"
     click_button "Save"
     expect(page).to have_content("Added todo list item.")
     within("div.todo_list") do
         expect(page).to have_content("Milk")
     end
 end

4) Viewing todo items displays the title of the todo list
  Failure/Error: within("h1") do
  Capybara::Ambiguous:
    Ambiguous match, found 2 elements matching css "h1"
   # ./spec/features/todo_items/index_spec.rb:9:in `block (2 levels) in <top (required)>'

此规范中的h1应为h2：

it "displays the title of the todo list" do
        visit_todo_list(todo_list)
    within("h2") do
        expect(page).to have_content(todo_list.title)
    end
end

Stuck - bin / rake不会通过Authenticating Rails ODOT
