BREAKING CHANGE: The Node Package Manager lock file `package-lock.json` is upgraded to version 2; while it is backwards with version 1 for the npm installer, consider this if you run any non-npm analysis tools that use the lock file (#8285)
* Adds supports-color so spec reporter dont output colors when not supported
* Adds babelrc so breakpoints dont jump around in specs
* Rename test to avoid duplicated name
* Removes unused methods
* Better naming for it_exclude
