title: How to perform A/B Testing in Polymer Web Components?
body: <p>I'm encountering a situation at a customer: they want to do A/B Testing.</p>
  
  <p>As far as I know, this most of the time happens at LoadBalancer level (Kubernetes) redirecting users to a certain version of the application (for example with new version of Gmail and a release is being rolled out).</p>
  
  <p>Now with web components, this customer wants to have a "dom-if" kind of situation where features are turned on if a certain requirement is met IN the component. This will add overhead of course.</p>
  
  <p>I wonder if this is the way to go. Their reasoning of this customer is that the component can be used in 100s of applications and then creating a build and working on it, might be too cumbersome and on the microlevel (as in IN the component) would be the best way to go. They are following Linkedin/AirBnB.</p>
  
  <p>As far as I know these companies are not using Web Components. </p>
  
  <p>The question is: what is advisable ? Doing the A/B testing on microlevel or on application-level (and use load balancers like kubernetes).</p>
