Why is the assertion `self.assertEqual(attendance_stats['total_paid_members'], 4)` failing, returning 1 instead of 4?

The test adds four members marked as PAID (SILVER/GOLD) but the get_membership_statistics() function only counts one. The most common causes are: 1) The filter that identifies paid tiers compares the status string to a hard‑coded value like 'PAID' instead of checking against the enum values for SILVER or GOLD. 2) The status field in the member objects is stored as an integer or enum, and the comparison uses a string, so only the first member that happens to match passes. 3) The function may break out of the loop after the first match, or it may reset the counter inside the loop. 4) The test data might not be correctly inserted into the database or in‑memory list, so only one record is visible to the function. To debug, print the list of members that get_membership_statistics() receives, log the status of each, and verify that the filter condition includes both SILVER and GOLD. Adjust the condition to something like if member.status in (Status.SILVER, Status.GOLD): count += 1. After that, rerun the test to confirm the count matches the expected 4.
