ReferenceError: Can't find variable: Mocha when running test #7

After upgrading to the latest version if gulp-mocha-phantomjs (0.8.0) that is depending on mocha-phantomjs-core (1.0.0) and therefore also got upgraded I have a set of test that report the following error:

ReferenceError: Can't find variable: Mocha
   at browser-shim.js:27

All required files in runner.html seem to be available and the test do work as expected in an actual browser like FF or Chrome. Any help would be appreciated.

Can you share your test.html, or at least how you're loading mocha?

ah yeah can you call mocha.ui instead of mocha.setup for now? I didn't know about mocha.setup... i need to investigate the differences, but a bug for sure.

Thank you for the feedback. I've now changed <script>mocha.setup("bdd");</script> to <script>mocha.ui("bdd");</script> but I still get the same error message:
ReferenceError: Can't find variable: Mocha at browser-shim.js:27

Do you still have the issue if you load mocha.js as the very first script?

I now rearranged the script to include mocha.js as the first script and this seems to have done the trick. It now also works with mocha.setup as expected. Would be please be so kind to elaborate a little on what went wrong before in the first place? Thanks a lot!

Glad it's working.

I don't know what's going on in HTTP://localhost:7777/q/p/lj_unittest/js/core.js and it's interaction with mocha. It could possibly be setting up an AMD or CommonJS environment and causing mocha to think it's not running in the browser and not set window.Mocha would be my guess.

Unlikely as it does work when running directly in the browser but I'm also glad it does work now. Thank you!
