ledger-scripts | Scripts I use with ledger

I recently learned about clasp, and became excited about the possibility of using TDD to edit my Google Apps Scripts (GAS) locally.

     NOTE: there might be a way to write tests using the existing GAS editor, but I'd prefer to use a modern editor if at all possible :)

clasp works great, but I cannot figure out how to mock dependencies for unit tests (primarily via jest, though I'm happy to use any tool that works)

• I got farthest by using the gas-local package, and was able to mock a single dependency within a test
  • However I could not find a way to mock multiple dependencies in a single test/call, and so I created this issue

• I am a javascript novice, and probably missed something important while researching this problem :)
• Despite installing @types/google-apps-script, I am unclear on how to "require" or "import" Google Apps Script modules whether using ES5 or ES2015 syntax, respectively--see below for an illustration of this.

Although there is a similar SO question on unit testing here, most of the content/comments appear to be from the pre-clasp era, and I was unable to arrive at a solution while following up the remaining leads. (Granted, it's very possible my untrained eye missed something!).

As I mentioned above, I created an issue (see link above) after trying to mock multiple dependencies while using gas-local. My configuration was similar to the jest.mock test I describe below, though it's worth noting the following differences:

• I used ES5 syntax for the gas-local tests
• My package configuration was probably slightly different
