Using mocha as my test framework, in my mocha.opts file I have the following option to tell mocha to use babel as the compiler:

--compilers js:babel-core/register

In my test file, my first line is:

import React from "react";

And when I run zuul with this test, I see the following output in the console:

import React from "react";
^
ParseError: 'import' and 'export' may appear only with 'sourceType: module'

Can someone please point me to where I setup zuul to use babel to make this work properly?
