未能测试创建动作

如何解决未能测试创建动作

| 我正在使用Rails 3.0.6和ruby 1.9.2，该应用程序可以在浏览器上运行，但无法测试。 1）我通过“ rails new myapp \”创建了一个新的Rails应用程序 2）生成支架\“ rails生成支架用户名：string hashed_password：string salt：string \” 3）之后，我更改了users_controller一点

  # 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

但是创建和更新测试失败谁能让我知道我做错了什么？谢谢

            if user = find_by_username(username)
                if user.hashed_password == encrypt_password(password,user.salt)
                    user
                end
            end
        end
    end

    private
        def password_must_be_present
            errors.add(:password,\"Missing password\") unless hashed_password.present?
        end

        def generate_salt
            self.salt = self.object_id.to_s + rand.to_s
        end
end

解决方法

assert_redirected_to user_path是单数。您甚至可能没有定义单一的user资源路由。您想要的可能是带有多个用户的assert_redirected_to users_path。
