159 Using Regression Testing to Preempt Website Errors with Micah Godbolt - Modules Unraveled Podcast

I’m really excited about today’s show because this is one of those topics that I know that I need to know, but don’t know where to start. So, I’m super excited that you agreed to come on and teach me what you know about regression testing!

## Regression Testing

   * Qualitative (Sasslint, JS lint, JSON lint)

   * Performance (Pagespeed, Perfbudget)

   * Visual Regression (wraith, phantomcss, webdrivercss)
