Question

我正在使用带有ruby 1.9.2的rails 3.0.6，该应用程序正在使用浏览器但不在测试..

1）我通过“rails new myapp”创建了一个新的rails应用程序

2）生成一个脚手架“rails generate scaffold user username：string hashed_password：string salt：string”

3）之后，我稍微更改了users_controller

  # 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）所以我也尝试修改测试：

 setup do
    @input_attributes = {
        :username               => 'username@goodmail.com',
        :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

但创建和更新测试失败

任何人都可以让我知道我做错了什么吗？

由于

Answer 1

assert_redirected_to user_path是单数。您可能甚至没有定义单个user资源路由。你想要的是assert_redirected_to users_path可能有多个用户。

无法测试创建操作
