Execution time limit testing?

I know there is a program memory limit for each problem 256MB. Is there program execution time limit enforced for each question in USACO test?

If there is, when I am going through past USACO questions for my practice, is there a way to know if my solution would have passed the time limit enforce during the test?

Same question for the memory limit, what’s the best way to test this during practice?

Does USACO has a platform that can help test your solution?
