positive.code:         is ideal for writing and running tests while developing the application. 
          It can be an integral part of the application build process.
          This chapter describes how to setup and run tests with karma.

      td(style="vertical-align: top") Protractor

negative.code:         In e2e testing, one process runs the real application
          and a second process runs protractor tests that simulate user behavior 
          and assert that the application responds in the browser as expected.
  
          使用`Protractor`来编写和运行_端对端(e2e)_测试。端对端测试**像用户体验应用程序那样**探索它。
          在端对端测试中，一个进程运行真正的应用，另一个进程运行Protractor测试，模拟用户行为，判断应用在浏览器中的反应是否正确。
