DDEV is a local development stack built on top of Docker. It gives you all of your environment needs without messy configured on your host machine, without needing to know Docker or configure your own containers. Which is great, and makes life easier. Instead of just using DDEV to develop your site or application locally, why not also run your tests within it?
I moved over to DDEV for my local development stack back in February. One of my favorite things is the ease of using Xdebug. You can configure Xdebug to always be enabled, or turn it on and off as needed (my preferred method.) When you have Xdebug enabled, it also enables it for any PHP scripts executed over the command line. That means you can debug your Drush or Drupal Console scripts like a breeze!
This article is based on using Xdebug within PhpStorm, as it is my primary IDE.
