How to test memory leak in CI /u/Legitimate-Lie-6196 Python Education

I am the maintainer of Glances and i want to add memory leak check in the Github pipeline.

For the moment, i use tracemalloc lib and the following PyTest code:

import time import tracemalloc def test_memoryleak_no_history(glances_stats_no_history, logger): """ Test Glances memory leak. """ tracemalloc.start() # First iterations just to init the stats and fill the memory logger.info('Please wait during memory leak test initialisation') iteration = 3 for _ in range(iteration): glances_stats_no_history.update() time.sleep(1) # Then iteration to measure memory leak logger.info('Please wait during memory leak test') iteration = 10 snapshot_begin = tracemalloc.take_snapshot() for _ in range(iteration): glances_stats_no_history.update() time.sleep(1) snapshot_end = tracemalloc.take_snapshot() snapshot_diff = snapshot_end.compare_to(snapshot_begin, 'filename') memory_leak = sum([s.size_diff for s in snapshot_diff]) // iteration logger.info(f'Memory consume per iteration: {memory_leak} bytes') assert memory_leak < 15000, f'Memory leak: {memory_leak} bytes' 

How do you handle that on you Python projects ?

Any advice concerning additional lib to use ?
