Mocha kann Module in importiertem Code nicht finden

Question

Ich habe eine Phoenix-App und versuche, Mocha für JavaScript-Unit-Tests zu bekommen. Ich möchte Modul 'Zwei' testen, das Modul 'Eins' importiert, aber ich kann nicht herausfinden, wie man Mocha konfiguriert, um Modul eins zu finden. Hier

ist der Testcode:

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()); 
    }); 
}); 

Hier ist der Ausgang, wenn ich 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; 
    ^

Die laufen Fehler ist ganz klar:

Error: Cannot find module 'web/static/js/one' 

Bedeutung der Pfad, den Sie nicht arbeiten zur Verfügung gestellt wird, versuchen Sie eine relative Pfade verwenden:

import {One} from "./one";
