Test if newer version break the tests before update

Probably would be cool if it is an answer, so when you select it, it will run npm test (by default) and if it breaks it probably ask you if you are sure to upgrade or not.

I got that idea from next-update, but i want to use npm-upgrade.

@th0r ping? Are you okey with the idea, so we can PR if someone want? I can find some time.

[th0r]

Yep, idea is nice but unfortunately I don't have time to implement it. PR would be great.

Okey, great! I'll see in next weeks :)
