"Join a faction" is good advice to give to any member of the game. Factions generally have resources to be able to equip you with what you'll need in this game (assigning a ship, getting you picked up from your starting planet, items, etc). They are often a good source of a person's first friends in the game, and also possibly some of the longest-standing friendships you may have. Factions can also provide you with tasks to do within the game, some of which may be a chore, and sometimes boring, but with the incomplete nature of the game they can give you direction when you might otherwise be struggling to find something to hold your interest. Faction work can also get you experience with portions of the game you would otherwise not have quick access to, and are a good source of knowledge and instruction on how to get ahead in the game, and use the various areas of the often-confusing interface.
Don't look upon joining a faction as a way to get Force-tested, but look at it as getting yourself started in the game. Pick a good faction, and chances are you'll want to stay there as long as you can, regardless of the Force.
That said, there are other ways to get Force tested besides speaking to the Jedi Academy or the Sith, but you have to know the right people. Finding these people without friends and resources is nigh impossible, so joining a faction is a good start to this end anyway.
