* Enable babel for tests
This enables babel for tests by using a mocha compiler
It uses the babel config from package.json
Transformed OptionsManager test to es2015 to see if it works
Removed the 5s timeout from cli tests, as the default timeout is already 10s, this should probably fix the timouts on travis that we had in babylon
Also run the cli tests on travis, they were disabled if istanbul active, but istanbul is always active on travis so we were never running this tests.
* ignore scripts directory
* only register for tests
* Set only flag correctly
* CLI: Only set options if different from default
Currently default values (like comments: true) will be set always for the transform.
This behaviour dos not allow for setting this options from babelrc as the default would always have precedence.
* Add new tests for comments
Also ensure that the babelrc in the fixture folder is copied over to the
working directory during tests
I'm extremely stupid and didn't commit as I go. To anyone reading this
I'm extremely sorry. A lot of these changes are very broad and I plan on
releasing Babel 6.0.0 today live on stage at Ember Camp London so I'm
afraid I couldn't wait. If you're ever in London I'll buy you a beer
(or assorted beverage!) to make up for it, also I'll kiss your feet and
give you a back massage, maybe.
