Is there a way for me to test my suitescript (restlet) outside of Netsuite? Currently I have to go to edit my script directly on Netsuite

You should use SuiteCloud Development Framework. When you start a new project in it you can include Jest unit testing to mock calls to the RESTlet.

@Ken You can use Postman to make HTTP calls to your Restlet.

For testing SuiteScript, the NetSuite debugger is great to see how code interacts within the NetSuite environment. For unit testing, Jest is a solid choice. I’ve got a GitHub project template that sets up a Jest testing environment for SuiteScript, which could streamline your testing process. Feel free to check it out and I hope it helps you as much as it’s helped others! NetSuite CustomModules Template: https://github.com/devnetkc/NetSuite-CustomModules-Template
