### How to run a test file?

Hello, I'm trying to run a test file, test_nucomp_timing.py, that tests the functionality of another file in sage's source code. test_nucomp_timing.py itself is not in sage's source code, but the file I'm testing is. Where should I put the test file, and which command should I use in order to run it? So far what I've tried is putting the file in sage's src folder and running the command "./sage test_nucomp_timing.py", but the first line of the test file is "from sage.schemes.hyperelliptic_curves import jacobian_morphism", which produces this error:

Traceback (most recent call last):

Is there anything I haven't set up properly? Thank you!
