@faizal.somani I suggest you to debug your scripts in netsuite sandbox (or dev instances), I don't think there is any eclipse plugin to leverage the netsuite debugging features directly into eclipse, so your script won't be linked to a netsuite instance and essentially just test the syntax

Eclipse does have this feature, and it does connect to your netsuite instance and load your data. Ive used it to test/create scheduled scripts. Eclipse does this by connecting to NetSuite and essentially the context is userinterface and has a 1000 governance https://web.archive.org/web/20170322102159/https://stackoverflow.com/documentation/netsuite/3828/getting-started-with-netsuite/13251/eclipse-suitecloud-ide-setup

I also did came across this in the netsuite help document!! indeed there is a way!!
