Fix configuration of Karma:
- Disable ES6 modules. The ES6 module transpiler is adding
"use strict" to all source files, this breaks e.g. chai or juggler
- Relax "ignore" setting to exclude only strong-task-emitter,
thus bring back Babel transpilation for chai and juggler.
Before this change, dependencies in node_modules (e.g. strong-remoting)
were not transformed to ES5 and thus crashed the tests in PhantomJS.
Note that loopback-datasource-juggler cannot be babelified to ES5
because it does not correctly support strict mode yet.
- Remove ES5 parser exception from .eslintrc
- Configure Karma to use Babel to transpile ES6 sources to ES5,
because PhantomJS does not support ES6
- Upgrade es5-shim to es6-shim
Notable side-effects:
- loopback no longer exports "caller" and "arguments" properties
- kv-memory connector is now properly added to the connector registry
- the file "test/support.js" was finally removed
- Move configuration of Karma unit-tests from `Gruntfile.js` to a
standalone file (`test/karma.conf.js`).
- Add a new Grunt task `karma:unit-ci` to run Karma unit-tests in
PhantomJS and produce karma-xunit.xml file that can be consumed
by the CI server.
- Add grunt-mocha-test, configure it to run unit-tests.
- Add `grunt test` task that runs both karma and mocha tests,
detects Jenkins to produce XML output on CI server.
- Modify the `test` script in `package.json` to run
`grunt mocha-and-karma` (an alias for `grunt test`).
The alias is required to trick `sl-ci-run` to run `npm test`
instead of calling directly `mocha`.
- Add `es5-shim` module to karma unit-tests in order to provide
ES5-methods required by LoopBack.
- Fix `mixin(source)` in lib/loopback.js to work in PhantomJS.
`Object.getOwnPropertyDescriptor()` provided by `es5-shim` does not
work in the same way as in Node.
