chrome-extension-i18n-shim v1.0.0
Chrome i18n testing shim
This project is an attempt to mimic the chrome.i18n.getMessage
function for testing. It's easy to stub out getMessage
with something like jest.fn
but we actually want to minic the implementation so we can verify tokens.
Setup
Install the dependency
yarn add -D chrome-extension-i18n-shim
In a Jest setup file (when used in conjunction with jest-webextension-mock):
// jest.setup.js
import { setupGetMessageSim } from 'chrome-extension-i18n-shim';
// We want to load our default translations into our tests. See: https://twitter.com/kentcdodds/status/1181591171518230528
import * as enMessages from './_locales/en/messages.json';
const getMessage = setupGetMessageSim(enMessages);
global.chrome = {
...global.chrome,
i18n: {
...global.chrome.i18n,
getMessage: getMessage,
},
};
