I have a Phoenix app and am trying to get Mocha wired up for javascript unit tests. I want to test module 'Two', that imports module 'One' but I can't figure out how to configure Mocha to find module one.
Here is the test code:
web/static/js/one.js
export var One = 1;
web/static/js/two.js
import {One} from "web/static/js/one";
export var Two = function () {return One + One;}
> test/js/two_test.js
import assert from 'assert';
import {Two} from "../../web/static/js/two";
describe('Two()', function() {
it('returns value 2', function () {
assert.equal(2, Two());
});
});
Here is the output when I run npm test
home:~/elixir/optitrue$ npm test
> # test /home/jon/elixir/optitrue
> mocha --compilers js:babel-register test/js/**/*.js
module.js:457
throw err;

The error is quite clear:

Meaning the path you provided doesn't work, try using a relative paths:
import {One} from "./one";

I am trying to set up a event handler for my bot. After I add the code and start the bot it outputs the error:
Error:

Code:
readdirSync("./events/").forEach((file) => {
const events = readdirSync("./events/").filter((file) =>
file.endsWith(".js")
);
for(let file of events) {
let pull = require(`./events/${file}`);
if(pull.name) {
client.events.set(pull.name, pull);
} else {
continue;
}
}
});
The error log leads me to this line 35
require('discord-buttons')(client); and to this line 119 let pull = require(`./events/${file}`)
This really seems confusing to me. Thanks in advance.

This is the error im getting do I have to require something else?
I have the exact same problem that is in this post How can you unit test Leaflet JS maps?
I was unable to comment or add additional questions to this post so I apologize for the duplicate question.

Instead of

you should use

You've used a really old example. Electron modules are collected under 'electron' in 0.35.0 more then two years ago ;)
From release notes:
Add electron module which includes all public APIs.
You'd better use tutorials from electron docs:
