Maybe we can remove the coverage checking from Windows as it will be checked in github? Could add coverage:win if we really want to check coverage in Windows.

@steven-supersolid I have a better idea for that,

we could create a spec/coverage.js that would use the env variable through process.env.CODE_COVERAGE set or not to start / not start the coverage instead of adding so many scripts
