I am getting this error

Cannot find module 'httpsGet' from 'functions/getSecureString.test.js'

httpsGet() is my own function, and is at the button of getSecureString.js, and called by getSecureString(). httpsGet() uses the https module to get content from a website that requires client side certificates.

Question

I am trying to mock httpsGet() and I am guessing the problem I have is because it isn't included with require() and hence jest.mock('httpsGet') fails.

Can anyone figure out if that is the case, and how I should fix it?
