This question already has an answer here:
I heard the terms "application-level testing" and "system-level testing". I think I know the difference, but I am not sure. I tried to do some research on the internet, but the closest explanation of the difference that I can find is this http://en.wikipedia.org/wiki/Software_testing#Unit_testing (unit testing and system level testing).
Does application-level testing mean the same as unit testing? This is not a homework question, I am just wondering if they are the same.
I am a student and still learning, I appreciate your help! Thanks.
