PR Checklist

Overview

Handle the corner case which can happen if:

  • You had a perfectly good package.json which npm was happy with
  • You decided to put mocha configuration inside your package.json
  • You left a stray comma in there, because you are used to more sensible configuration file formats ;-)
  • Instead of running npm test you ran mocha directly (with npx or just mocha.js)

As detailed here: https://github.com/dhdaines/mocha-5141

Since `readFileSync` is only stubbed `onFirstCall` we get a different answer
the second time around which is probably Not What You Want.  But also we
*already checked that config = false*.  So you could just remove this
test, it does nothing useful.

Btw @dhdaines, just a heads up, the - [ x ]s in the description can be - [x]s (no spacing) to work with GitHub's task lists. I edited them just now. 🙂

Ohhh! Thank you, I have been wondering about that for ages now! (suppose I should have RTF the Markdown manual...)

Ah, I suspect that the more obviously invalid JSON will break the too-specific assertion in the test... will fix it in a second.
