title: Angular 1.x testing are good for angular 2?
body: <p>I'm starting a new app that is made with angular 1.x, and I'm thinking about changing to angular 2. Do you recommend me to do that? </p>
  
  <p>A part of that question, the most important one is that I want to know if Angular testing using Karma and Protractor are good for Angular 2. If I switch to Angular 2, can I run the tests to verify if the functionality still being the same? </p>
  
  <p>I don't have the tests yet, so if I have to do it in a special way in order to be able to do that is welcome too. </p>
