Javascript

I want scripts errors of CRM( on premise) 2015.

i used customcodevalidationtool2015 this tool,it works good but it doesn't tell errors on events like

Onsave of form 

Onload of form

Onchange of field

So what will be the best way to work on this.

One way is to check events for every form and than one by one raise these event and get the reuslt,but that will be very tedious.

I want some solution which minimize my work
