How to make it work with sinon-chrome in tests

[dsrini-open]

With the Fix 190 [https://github.com//pull/190], the polyfill does not work on outside extension context.
What about the tests? Have imported in each page in source files using -
import browser from "webextension-polyfill";
which is causing the tests to fail with -

Error: This script should only be loaded in a browser extension.

How are you running tests?

@Rob--W - Through mocha. I am using sinon-chrome for test purposes.

Meanwhile the workaround that I found is the following -

  if (!chrome.runtime) chrome.runtime = {};
  if (!chrome.runtime.id) chrome.runtime.id = "history-delete";

Having this in the setup.js file, running it first before everything works.

Just chrome.runtime.id = "testid"; should be sufficient. sinon-chrome does declare a chrome.runtime.id property, but its value is null, which caused the duck-typing to fail.
