assert DEFAULT_IGNORE_LIST includes threading and queue so standard concurrency primitives keep real monotonic time
assert configure(default_ignore_list=...) purges threading and queue, causing queue.Queue.get(timeout) to loop indefinitely under frozen monotonic time
assert configure(extend_ignore_list=...) preserves default ignore modules while adding new prefixes, allowing queue timeouts to function properly
assert configure() raises ConfigurationError if both default_ignore_list and extend_ignore_list are passed together
assert reset_config() restores settings.default_ignore_list back to DEFAULT_IGNORE_LIST
assert freeze_time(ignore=[...]) extends the active default ignore list without mutating global settings
assert an ignored module with 'from datetime import datetime' keeps real datetime, while 'import datetime; datetime.datetime.now()' is frozen
assert an ignored module's calls to time.time() and time.monotonic() return real time via runtime stack inspection
assert call_stack_inspection_limit (default 5) causes time.time() called through unignored helper wrappers beyond depth 3 to silently revert to frozen time
assert setting call_stack_inspection_limit to 0 completely disables runtime caller inspection, forcing all modules to read frozen time
assert real_asyncio=True enables real monotonic time for asyncio event loop timers while real_asyncio=False freezes loop timers
