No Coverage Information Collected using Istanbul ... Babel...?

[nelsonic]

At the moment when attempting to run the tests using istanbul to collect coverage stats, we get:

"No coverage information was collected, exit without writing coverage information"

I suspect this might have something to do with: https://github.com/gotwarlost/istanbul/issues/262#issuecomment-168280240

We should investigate _why_ istanbul :broken_heart: babel ...

Build passes on Travis, but no coverage info collected: https://travis-ci.org/dwyl/ampl/builds/103661684#L272

easy quick fix is to write tests in es5 and test the lib folder rather than src. atm they are not really benefiting from from es6 features

[nelsonic]

@des-des agree that when no ES6 amazing benefits are required we should default to using _ES6_ however at the moment the tests are importing the src files ... so we would need to switch to using the lib/ampl.js instead which would mean running npm run build before running the tests...

ops I think we are both pushing solutions to this. my bad.

@des-des if you have time to investigate this, please assign to yourself and I'm happy to work on other stuff. you'll probably figure it out fastererer than me... :racehorse:

ill give it a go

@des-des did you see: https://github.com/ambitioninc/babel-istanbul/issues/51#issuecomment-173326875 ? I've just pushed a commit that _might_ work... https://travis-ci.org/dwyl/ampl/builds/103678920 promise I will leave it alone after that last commit. need to catch up on work... hope you're having a good evening. (don't work toooo hard...)

maybe have too much fun..
