we are trying to add tests to out internal application for suite script and was wondering how to have unit tests that are built on top of Netsuite module for example

function openSuitle(id, invoice, type = "Bill") {
    return url.resolveScript({
      scriptId: **********,
      deploymentId: "************",
      returnExternalUrl: false,
      params: {
        recid: id,
        invoice: invoice,
        type: type,
      },
    });
  }

This is not a function I would unit test, personally. You're just re-testing that

resolveScript()

works. It's not our job to unit test the SuiteScript API, and there's no recourse you can take if it fails. That said, in order to test this function, you'll have to mock the

url

module and its

resolveScript

function.
