Rails 测试设计控制器的简单示例

Question

我想要一个最简单的例子来测试新注册（电子邮件、密码、密码确认）的设备操作属性的有效性，sign_in 和 forgot_password。互联网上到处都是 RSpec，但我想使用 Rails 4.2 给我的东西，但绝对没有。

我坚持使用默认实现：

require 'test_helper'

class RegistrationsControllerTest < ActionController::TestCase

  def setup
    @controller = RegistrationsController.new
    @request    = ActionController::TestRequest.new
    @response   = ActionController::TestResponse.new
    @request.env["devise.mapping"] = Devise.mappings[:user]
    @user = Registrations.new(username: "John", email: "myemail@email.com")
  end

end

我知道这不算太多，但我正在迈出 TDD 的第一步，所以请不要开枪！

如何检查用户属性的有效性，例如电子邮件地址为零或密码为 100 个字符？

您可以检查 rails 内置 minitest

我假设你有压倒一切的设计registration_controller。

在控制器的 tdd 中，您可以编写测试用例以执行操作。检查修改后的代码：-

require 'test_helper'

class RegistrationsControllerTest < ActionController::TestCase
  include Devise::TestHelpers # for including devise's actions

  def setup # this set up default settings for controller
    @controller = RegistrationsController.new
    @request    = ActionController::TestRequest.new
    @response   = ActionController::TestResponse.new
    @request.env["devise.mapping"] = Devise.mappings[:user]
    @user = Registrations.new(username: "John", email: "myemail@email.com")
  end

  setup do # this used for setting global variable used in test file 
    @user= users(:one) # users is the fixture file of test in which you can set default data for test environment.
  end

  test "should create user" do # then you test cases for controller
    sign_in users(:one)
    post :create, users:{email:'test@test.com, password:'XXXX'...}# you can pass arguments for create method. Please check it once, i am not sure about names
    assert_response :success 
  end


end

Rails minitest 提供了一些 assertion.
