No an emissions test will not affect the check engine light.
However an emissions test cannot be performed while the check engine light is on, you will have to repair whatever is wrong with the vehicle before it can be done.
Simply resetting it wont work either as the system will have to complete several (7 or 8) emissions readiness tests before it can be done and whatever is wrong will most likely reappear by then.
