Rspec: everyday-rspec实操。5：controller test（了解基础）

第 5 章 控制器测试 

5.1基础

rails generate rspec:controller home 

      # be_success 检查响应的状态是成 功(200 响应)还是失败(例如 500 异常)。

      expect(response).to have_http_status "200" 

be_success匹配器 ,have_http_status()匹配器

5.2要验证身份的controller test

如果程序有Devise。测试的时候，需要身份验证，则使用Devise Test helpers

Devise includes some test helpers for controller and integration tests. In order to use them, you need to include the repective module in you test cases/specs. 

包含一个测试模块.

class PostsControllerTest < ActionController::TestCase
include Devise::Test::ControllerHelpers
end

class PostsTests < ActionDispatch::IntegrationTest
include Devise::Test::IntegrationHelpers
end

RSpec.configure do |config|
config.include Devise::Test::IntegrationHelpers, type: :feature

 config.include Devise::Test::ControllerHelpers, type: :controller

 config.include Devise::Test::ControllerHelpers, type: :view

end

然后就可以使用sign_in, sign_out方法了

redirect_to 匹配器 

以下测试都是get的测试。

5.3 测试用户输入。

HTTP GET外，还有POST, PATCH, DELETE与controller交互。
