The BEST way to find BUGS in an API | Contract vs Approval Testing

Restful booker is a small service that is chock full of bugs, deliberately, it’s designed as an exercise for testers. I wrote some tests for it using the Approval testing tool TextTest in a previous video, but I wasn't really showing how to find bugs. Specmatic is another open source testing tool that works slightly differently - it's a Contract testing tool. This video looks more closely at the best way to expose bugs in an API, using Restful booker as an example. So, is TextTest or Specmatic better?
