title: In Wordpress, how do I display a single random post of a custom post type in a sidebar widget?
body: <p>I have created a custom post type - Testimonials - for a WP site I am working on. I want to display a single random testimonial in my sidebar - without using a plugin if possible. Do I need to create a text widget with the proper post query? If so, what would it look like?</p>
  
  <p>Many thanks,</p>
