1.  Xray provides a setting ("Max number of Tests per Test Plan") where you may define a soft limit for the number of Tests within Test Plans. Although you may adjust this value, we recommend having no more than 2000 5000 Tests in a given Test Plan:
   1. to ease their management;
   2. and to make it more performant and lighter.
   This limit may be easily superseded depending on Jira instance deployment configuration.
