mocha-babel-test

Using mocha and babel-core/register running ES6 tests. Chinese charactors will cause error when compile without cache.

Reproduce Steps

• npm install

• npm test

First time running the test, we will get ReferenceError: recursiveFunc is not defined

• then npm test

the test will pass.

• if we run npm run test-no-cache

The error will appear again.

But, if we delete the comment "//要瘋了", first line at index.js

• npm run test-no-cache

the test will pass

and if we change the method of recursive function delcare from

var recursiveFunc = function () { ... }

to

function recursiveFunc () { ... }

This error will not appear
