Friendship test I made up to avoid wasting time on someone who will eventually do something ugly to you. 
Give +1, 0, -1 or -5 for positive, neutral/unknown, negative or extreme negative. Stay away from people with a total score in the negatives. You can know people for years and never really know the answers to some of these questions but you
 can still get a good idea. If nothing else it can help with closure with past failed relationships.

1. Empathy/understanding Do they understand you? Do they understand others? Or do they misjudge? Are they quick to condemn?
2. Openness/honesty. Do they communicate well? Do they tell you what they're thinking? Do they admit negative things about themselves?
Do they keep from you what they're thinking? Do you feel like you need to read their mind? Do they refuse to talk about things? Do they actively lie?
3. Ethics. Do they seem only concerned about themselves? Do they just offer right up some crappy thing they did without understanding it was wrong?
4.  Intelligence/knowledge. Do they read books? Do they use google? Are they curious about the world? Do they like to learn new things?
5. Can they ever change their mind? Apologize? Admit they were wrong?

You can figure out #1, their empathy/understanding, by getting them to talk about others. Not necessarily nasty gossip about mutual acquaintances. Can be just someone in the news, speculating about their possible motives.

For #2 of course some people are great at lying but this is just as much about how open they are in general. Do they just really talk to you about all the stuff they're thinking? Do they ever admit to anything negative about themselves? If definitely yes,

they get a +1. If definitely no, they get a -1 even if they never actually lie. An additional issue here is people are unlikely to be open at first. Sometimes you're just ready to open up before they are. Don't be too quick to give them a negative score.

#3 can seem difficult to determine in that people hide the ugly unethical stuff they do. But just see if in general they show any concern for what you're feeling. Any concern for your happiness. You don't have to be a detective concerning their past but if they tell you they did something that sounds pretty bad in passing, don't let it pass. Question them about it.
