Except the only way for your god to test someone is to control others and there to be "collateral damage" to others. For example testing Robertson by making him rich has the consequence of making other people poorer. Testing someone's patience by making rush hour longer means mind controlling the other motorists. An all-knowing god, knows the results of a test before it is given so omniscience is only possible if there is no free will. Without free will we are not responsible for our actions (unless said god is evil). Since your god controls some people to "test" others, there is no free will and louisadkins' claim grows strong.

With your argument, there is no effective difference between a god who "tests" people in a variety of ways and there being no god whatsoever and we live in a universe with free will and as a consequence of having free will and no one micromanaging, good things will happen to people whether or not they deserve it and bad things will happen to people whether or not the deserve it. Just like the universe today.
