Terry J. Reedy <tjre...@udel.edu> added the comment:
On Windows with current master, the baseline for running anything with 1 import
(">>> import sys; len(sys.modules)") is 35 imported modules. Adding "import
unittest" increases this to 80. What slightly puzzles me is that running
---
import unittest
import sys
class Tests(unittest.TestCase):
def test_bug(self):
print("len(sys.modules):", len(sys.modules))
if __name__ == "__main__":
unittest.main()
---
increases the number to 90. Perhaps unittest has delayed imports.
The current startup number for IDLE is 162, which can result in a cold startup
of several seconds. I am thinking of trying to reduce this by delaying imports
of modules that are not immediately used and might never be used.
For tests, I gather that side-effect issues are more important than startup
time.
