I need real life project data ,data from requirements stage to bug open/close (all dev process).
I would appropriate if you could share it with me as I need it for testing my AI Add-on to Jira.
The problem with "real Jira data" is that it belongs to someone and they are likely to have data security rules of some form. Plus, it might not be of any use to you because it won't test what you're doing.
I suspect you are going to have to generate your own.
