Question

When I switch from Chrome to PhantomJS I get the following errorh
Starting 'unit'...

Here is the karma.conf.js generated by Aurelia.
"use strict";
const path = require('path');
const project = require('./aurelia_project/aurelia.json');
const tsconfig = require('./tsconfig.json');
let testSrc = [
{ pattern: project.unitTestRunner.source, included: false },
'test/aurelia-karma.js'
];
let output = project.platform.output;
let appSrc = project.build.bundles.map(x => path.join(output, x.name));
let entryIndex = appSrc.indexOf(path.join(output, project.build.loader.configTarget));
let entryBundle = appSrc.splice(entryIndex, 1)[0];
let files = [entryBundle].concat(testSrc).concat(appSrc);
module.exports = function(config) {
config.set({
basePath: '',
frameworks: [project.testFramework.id],
files: files,
exclude: [],
preprocessors: {
[project.unitTestRunner.source]: [project.transpiler.id]
},

I ran into this issue just now. I 'solved' it by modifying aurelia-karma.js at line 49 from:
let originalDefine = global.define;
to:
var originalDefine = global.define;
Currently don't have time to find a root cause for this, may come back and edit later. Suspect this might be a typescript/transpiling issue with let compatibility.
