每当按下 composition/index.html.erb 中的“保存”按钮时，就会完成一个 ajax 请求并附加一行来显示同一页面中的 Composition.content 字符串。但我的黄瓜测试显示错误：

Feature: User creates compositions

  Scenario: User creates a composition                                                   # features/composition.feature:2
    Given I go to the compositions page                                                  # features/step_definitions/composition_steps.rb:1
    And I fill in "Content" with "My Globe number: +63-916-475-4261"                     # features/step_definitions/composition_steps.rb:5
    When I press "Save"                                                                  # features/step_definitions/composition_steps.rb:9
    Then I should see "My Globe number: +63-916-475-4261" added in the compositions page # features/step_definitions/composition_steps.rb:18

是否由于此时尚未呈现添加的行而导致错误？请给我一些答案。谢谢！

以下是涉及的文件。

组成.特征

Feature: User creates compositions
  Scenario: User creates a composition
    Given I go to the compositions page
    And I fill in "Content" with "My Globe number: +63-916-475-4261"
    When I press "Save"
    Then I should see "My Globe number: +63-916-475-4261" added in the compositions page

composition_step.rb

Given /^I go to the compositions page$/ do
  visit compositions_path
end

Given /^I fill in "(.*?)" with "(.*?)"$/ do |arg1, arg2|
  fill_in(arg1, :with => arg2)
end

When /^I press "(.*?)"$/ do |arg1|
  click_button 'Save'
end

Then /^I should see "(.*?)" added in the compositions page$/ do |arg1|
  page.should have_content(arg1)
end

组合物/index.html.erb

<%= form_for @new_composition, remote: true do |f| %>
  <%= f.label :content %>
  <%= f.text_field :content %>
  <%= f.submit 'Save', id: "composition_submit" %>
<% end %>

<h1>Listing compositions</h1>

<table id="compositions_table">
<% @compositions.each do |composition| %>
  <tr>
    <td><%= composition.content %></td>
  </tr>
<% end %>
</table>

composition_controller.rb

class CompositionsController < ApplicationController
  def index
    @new_composition = Composition.new
    @compositions = Composition.all

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @compositions }
    end
  end

  def create
    @composition = Composition.new(params[:composition])

    respond_to do |format|
      if @composition.save
        format.js
        format.json { render json: @composition, status: :created, location: @composition }
      else
        format.js
        format.json { render json: @composition.errors, status: :unprocessable_entity }
      end
    end
  end
end

创建.js.erb

$('#compositions_table').prepend("<%= j(render('compositions/composition', composition: @composition)) %>")

在 composition_step.rb 中试试这个

When /^(?:|I )fill in "([^\"]*)" with "([^\"]*)"$/ do |field, value|
 fill_in(field, :with => value)
end

When /^(?:|I )press "([^\"]*)"$/ do |button|
 click_button(button)
end

Then /^I should see "([^"]*)" within "([^"]*)"$/ do |text, selector|
  find(:xpath, "//#{selector}[contains(text(),'#{text}')]").should_not(be_nil, "Could  not find the text '#{text}' within the selector '#{selector}'")
end

Then /^I should see "(.*?)" added in the compositions page$/ do |text|
  page.should have_content(text)
end

像这样的场景

Scenario: User creates a composition
    Given I go to the compositions page
    When I fill in "Content" with "My Globe number: +63-916-475-4261"
    And I press "Save"
    Then I should see "My Globe number: +63-916-475-4261" added in the compositions page
