Is the Testament of Solomon Biblical?

Okay so I was looking around on google for some answers about where some of the demon names that are "Biblical" came from, and I came across the Testament of Solomon . It isn't in the Bible from what I can tell. (It may be, if so, can I have some references?). It is an account of how Solomon enslaved demons using Michael's ring and made them rebuild the temple. There's something about all of this that just feels off. Does anyone know if its considered true by the majority or if its just considered untrue?
