The global variable current_test_number is being modified in _handle_case which appears to be called from multiple threads based on the comment 'Run cases with multiple threads'. This creates a race condition where multiple threads could increment the counter simultaneously, leading to incorrect progress reporting.

Suggested change
start_time = time.time()
start_time = time.time()
# Ensure thread-safe increment of current_test_number
with current_test_number_lock:
current_test_number += 1

This increment operation is not thread-safe. When multiple test cases run concurrently, the progress counter will be inaccurate due to race conditions. Consider using a thread-safe counter or moving this logic to a synchronized section.

progress_str = f"({current_test_number:3d}/{total_test_count:3d})"
