新型号规格上的水豚+ RSpec问题

Question

所以我没有测试就制作了我的第一个Rails应用程序。现在我正在重新测试应用程序并首先进行测试。我正在为我创建的模型（Task）提出请求规范。我正在测试创建新任务的表单。

任务的数量应该改变1（即，保存了新的任务），但是它没有改变。我基本上遵循迈克尔哈特尔的代码。

Error: 
1) Task Pages Creating a Task with valid information creates a Task 
    Failure/Error: expect { click_button "Create task" }.to change(Task, :count).by(1) 
    count should have been changed by 1, but was changed by 0 
# ./spec/requests/tasks_pages_spec.rb:22:in `block (4 levels) in <top (required)>' 

相关代码： 型号

class Task < ActiveRecord::Base 
    attr_accessible :begin_time, :day, :end_time, :gear, :notes, :preset, :room, :setup,     
    :strike 

    validates :room, presence: true 
    validates :begin_time, presence: true 
    validates :end_time, presence: true 
    validates :gear, presence: true 
    validates :day, presence: true 
end 

控制器

def new 
    @task = Task.new 
end 

def create 
    @task = Task.new(params[:task]) 

    if @task.save 
    redirect_to root_path 
    else 
    render 'new' 
    end 
end 

集成测试

require 'spec_helper' 

describe "Task Pages" do 

    subject { page } 

    describe "Creating a Task" do 

    let(:submit) { "Create task" } 
    before { visit new_task_path } 

    describe "with valid information" do 
     before do 
     fill_in "Day", with: Date.today 
     fill_in "Room", with: "6W-002" 
     fill_in "Begin", with: Time.now 
     fill_in "End", with: 1.hour.from_now 
     fill_in "Gear", with: "LCD" 
     end 

     it "creates a Task" do 
     expect { click_button "Create task" }.to change(Task, :count).by(1) 
     end 

    end 
    end 
end 

而且形式

<%= form_for(@task) do |t| %> 

    <%= t.label :day %> 
    <%= t.text_field :day %> 

    <%= t.label :room %> 
    <%= t.text_field :room %> 

    <%= t.label :begin_time, "Begin" %> 
    <%= t.text_field :begin_time %> 

    <%= t.label :end_time, "End" %> 
    <%= t.text_field :end_time %> 

    <%= t.label :gear %> 
    <%= t.text_field :gear %> 

    <%= t.label :day %> 
    <%= t.text_field :day %> 

    <%= t.submit "Create task", class: "btn btn-large btn-primary" %> 
<% end %> 

Answer 1

您的表单中有:day字段两次。第一名可能是由你的测试填充，然后在第二名中被空值破坏。
