I had trouble getting a jest (JavaScript testing library) mock to work

import * as pdfPreview from "../pdfPreview"
pdfPreview.displayPdf = jest.fn()


The problem was that the function's real name was displayPDF() (vs. displayPdf above) and there was no error thrown because I had mocked the wrong property . I got caught out because my function name used capitals in it, which is non-standard.

In future I should enforce that even acronyms are lowercase in my functions. Or adopt a convention at least.
