在rails RESTfull控制器中测试创建动作的正确方法是什么？

Question

我在其中创建操作定义为users_controller.rb文件： -

def create 
    @user = User.new(user_params) 
    if current_user.g_admin? 
    @user.role = 'c_admin' 
    elsif current_user.c_admin? 
    @user.role = 'c_user' 
    end 
    @user.admin_provisioned = true 
    authorize @user 
    respond_to do |format| 
    if @user.save 
     format.html { redirect_to authenticated_root_url, notice: 'User was successfully created and email has been sent.' } 
     format.json { render :show, status: :created, location: @user } 
    else 
     format.html { render :new } 
     format.json { render json: @user.errors, status: :unprocessable_entity } 
    end 
    end 
end 

现在，我想编写测试这种方法反映了该方法的所有行为。我对测试完全陌生，所以编写测试的详细和标准方式将被接受为答案。 rspec的版本是3.4。快乐的编码。

所以你可以用rspec和水豚来测试这个方法。对于填充部分，您必须使用您的页面上的输入元素。

describe "let an guest create a user account" do 
    fill_in :user_object, with: "value" 

    click_button "Save User" 

    expect(page).to have_content("User was successfully created and email has been sent.") 
end 


describe "let an guest try to create an account with invalid data" do 
    fill_in :user_object, with: "invalid value" 

    click_button "Save User" 

    expect(page).to_not have_content("User was successfully created and email has been sent.") 
    expect(page).to have_content("content from the :new page") 
end
