Mocking process argv with native node mock

Question

I am migrating from sinon to the native node:test library.

Before I mocked argv with sinon like so;

import { stub } from 'sinon'

stub(process, 'argv').get(() => ['node-path', 'application-entry', 'first-arg']

The following with node:test is not working;

import { mock } from "node:test"

mock.getter(Process, 'argv').mock.mockImplementation(() =>  ['node-path', 'application-entry', 'first-arg'])

I get the following error;

TypeError [ERR_INVALID_ARG_VALUE]: The argument 'methodName' must be a method. Received undefined

Answer 1

I never found a solution to this (and mocking many other native libraries with the native mocking library) but in this case I did the obvious and injected argv into a function and didn't bother testing it directly
