How do I make Chrome accept “.test” as a valid TLD?

Question

When I enter, say, xyz.test in the Chrome address bar, then Chrome initiates a search. How do I make Chrome always treat .test as a top level domain, just like .com and all the others?

I know that I can just put http:// in front, but I tend to forget that, especially when editing an address that has already been entered. By the way, that's another annoyance: I would like to have Chrome always show the http:// in the address bar.

Just found out that the iglvzx's proposal, sent in reply to another user's inquiry, offers a partial workaround:

You can implicitly do this by creating a new search engine with a URL of http://%s and keyword of null. Then, set this as the default search engine.

I say partial workaround since now the default search functionality in the address bar is entirely disabled. For the time being, I marked my answer as accepted. But I may change that, if someone offers a better solution!
