How to run a test file?

edit

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):
  File "/mnt/c/Users/Raine/sage/test_nucomp_timing.py", line 1, in <module>
    from sage.schemes.hyperelliptic_curves import jacobian_morphism
  File "/mnt/c/Users/Raine/sage/src/sage/schemes/hyperelliptic_curves/jacobian_morphism.py", line 119, in <module>
    from sage.schemes.generic.morphism import SchemeMorphism

  File "sage/rings/integer.pyx", line 1, in init sage.rings.integer
  File "sage/rings/rational.pyx", line 79, in init sage.rings.rational
ImportError: cannot import name ZZ

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