No.
Even the Universal Limuis or whatever its called is not that great for determining a sue/stu.
Here's some things to think about:
-Is your character overly beautyful for no reason and no one else can come close to matching her/his beauty?
-Does every character love/admire her/him and the only ones that hate him/her are just jellous for no reason?
-Do all the girls/guys fight over her/him for no reason?
-Does she/he break the rules that where astablished in the story for no reason?
-Is her/his ONLY character flaw is his/her clumsyness?
-is she/he the only one to get spechal treatment from cops, teachers/bosses, etc... for no reason(or cause she's/he's hot/amazing/popular/ect...) Or does she/he get away with cheating/attacking/killing/whatever for no reason?
-Is she/he just spechal for no reason?
Thats basicly it. A characters name could be God(though not a good idea), and depending on how she/he is wriiten, she/he could proably not be a Sue/Stu. Also, there's nothing wrong with baseing a character off of you. It can make a character seem more real and relateable. Though if her only purpouse is wish fulfillment, then thats where it's bad.
Also, it's not always bad to have a Stu/Sue. Take Harry Potter for example. He's pretty much a Gary Stu, though despite all that, he still got some chatacter in him and got some fans with him. Also, Mary Poppins was a fun women that a lot of people irl loved, even though she's a Mary Sue. Just write what you want and don't worry about things like Gary Stu/Marry Sue.
While I don't agree with the other guy, this is just as bad as any sue test. No context is addressed.
What is 'no reason' for those? Can they be jealous because the other character is prettier or flirting with their lover, or do you mean random jealousy that has no context and shows up arbitrarily? What if they're jealous, but don't act on it?
Why is clumsiness bad? Sure it's often a symptom of a Sue, but not only Sues have it. Does the character have parkinsons? Are they of a completely different rank or occupation of the other characters? Do they have vision, balance, musculatory, or bone problems?Are they just a klutz more than others?
The last one has more of an issue with sues, but remember, many stories have issues where characters have bent the rules of the universe, not broken them. The boundaries need to be more established.
