Ruby on rails 3 -测试创建操作失败

Question

我正在玩rails 3.0.6与ruby 1.9.2，该应用程序正在浏览器上运行，但未在测试中…

1)我创建了一个新的rails应用程序"rails new myapp"

2)生成脚手架"rails生成脚手架用户username:string hashhed_password:string salt:string"

3)之后，我改变了users_controller一个位

  # POST /users
  # POST /users.xml
  def create
    @user = User.new(params[:user])
    respond_to do |format|
      if @user.save
        // change @user to usrs_url
        format.html { redirect_to(users_url, :notice => "User #{@user.username} was successfully created.") }
        format.xml  { render :xml => @user, :status => :created, :location => @user }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @user.errors, :status => :unprocessable_entity }
      end
    end
  end
  # PUT /users/1
  # PUT /users/1.xml
  def update
    @user = User.find(params[:id])
    respond_to do |format|
      if @user.update_attributes(params[:user])
        // change @user to usrs_url
        format.html { redirect_to(users_url, :notice => "User #{@user.username} was successfully updated.") }
        format.xml  { head :ok }
      else
        format.html { render :action => "edit" }
        format.xml  { render :xml => @user.errors, :status => :unprocessable_entity }
      end
    end
  end

4)所以我也试着修改测试:

 setup do
    @input_attributes = {
        :username               => '[e-mail]',
        :password               => 'secret',
        :password_confirmation  => 'secret'
    }
    @user = users(:one)
  end
  test "should create user" do
    assert_difference('User.count') do
      post :create, :user => @input_attributes
    end
    assert_redirected_to users_path
  end
  test "should update user" do
    put :update, :id => @user.to_param, :user => @input_attributes
    assert_redirected_to users_path
  end

但是创建和更新测试失败

谁能告诉我我做错了什么?

Answer 1

assert_redirected_to user_path是奇异的。您甚至可能没有定义单个user资源路由。您想要的可能是assert_redirected_to users_path与复数users。
