Rich Snippet for testimonials without star ratings

[tmg.seo]

A product in our website has testimonial, but does not have ratings? Would Google rich snippets include these?

Is there an example out there?

I'm assuming you'd like to have 5 star ratings for the product?

Can you go back to those people who gave you a testimonial and get them to give you a rating out of 5? If so then great, but if not perhaps you can judge each review fairly and come up with a star rating.

Once you've done this you can use Schema.org (try the Schema Creator if you're not sure how) or hReview to try and get some rich snippets showing.

Use the Rich Snippets Testing Tool or Bing Webmaster Tools to validate.
