# TODO: Add more tests for each hook and interaction
# - broker_started, broker_stopped
# - service_created, service_started (and service_stopped when broker supports it)
# - remote_action (might require mocking Transit)
# - local_event
# - Multiple middlewares and their execution order
# - Middlewares modifying context and results

# Placeholder for Action and Event if not directly available or for simpler testing
# class Action:
#     def __init__(self, name):
#         self.name = name

# class Event:
#     def __init__(self, name):
#         self.name = name

# Make sure to adjust imports for Action/Event based on where they are defined in pylecular
# from pylecular.registry import ActionEndpoint as Action, EventEndpoint as Event
# Using ActionEndpoint and EventEndpoint as placeholders, adjust if these are not the correct classes.
# The example assumes Action/Event objects have a 'name' attribute.
# If they are just strings (action_name, event_name), then TestMiddleware._record_call needs adjustment.
# Based on Broker code, 'endpoint' objects (ActionEndpoint, EventEndpoint) are passed, which should have a 'name'.
# For instance, in Broker.call:
# handler_to_execute = self._apply_middlewares(endpoint.handler, "local_action", endpoint)
# So, 'endpoint' is the metadata. The hooks in middleware.py are defined as:
# def local_action(self, next_handler, action): -> action is the metadata (endpoint)
# def remote_action(self, next_handler, action): -> action is the metadata (endpoint)
# def local_event(self, next_handler, event): -> event is the metadata (endpoint)
# This seems consistent.
# Final check on broker_created sync nature:
# In Broker.__init__:
# for middleware in self.middlewares:
#     if hasattr(middleware, 'broker_created') and callable(getattr(middleware, 'broker_created')):
#         middleware.broker_created(self)
# This is a direct synchronous call. TestMiddleware.broker_created must be synchronous.
# The provided example code for TestMiddleware.broker_created is:
#         def broker_created(self, broker): # Should be synchronous
#            self.called_hooks.append({"name": self.name, "hook": "broker_created", "broker_id": broker.id})
# This is correct. My _record_call_sync helper also works for this.
# The change to `hasattr(res, '__setitem__')` in local_action/remote_action is to handle cases where `res` might be a Context object or other non-dict mapping.
# Context objects in pylecular might not be simple dicts.
# Ensure params in local_event is a dict before modification.
# Corrected imports for Action and Event to ActionEndpoint and EventEndpoint as per pylecular.registry.
# The broker_instance fixture is simplified. If tests require a fully started/stopped broker, it should be enhanced.
# The test_broker_registers_middlewares_direct assertion was refined to check the content of called_hooks.
# The test_broker_registers_middlewares_via_settings was also refined.
# Added a basic test for the broker_instance fixture itself.
# Commented out the more complex test_local_action_middleware_wrapping as it's illustrative and depends on more setup.
# Added a note that Context.params should be checked/initialized in local_event if it could be None.
# Made _record_call_sync and _record_call_async to clearly distinguish. broker_created calls the sync one.
# All other async hooks call _record_call_async.
# For wrapping hooks, ensured that if `res` is a dict, it's modified. If it's a Context, it might need specific handling.
# The current pylecular.context.Context does not directly support item assignment like a dict for arbitrary keys.
# So, the modification `res["local_action_processed_by"] = self.name` might fail if `res` is a Context object.
# The actions in pylecular typically return dicts or basic types, not the Context object itself.
# So, `isinstance(res, dict)` should be sufficient for now.
# The `local_event` handler should ensure `ctx.params` is a dictionary before trying to set a key on it.
# Added this check: `if ctx.params is None: ctx.params = {}`
# The example's Action/Event imports were `from pylecular.registry import Action, Event`.
# I've used `from pylecular.registry import ActionEndpoint as Action, EventEndpoint as Event`
# This seems more aligned with how endpoints are handled in the broker.
# If `Action` and `Event` are indeed the classes for metadata, then this is correct.
# If the actual metadata objects are different, TestMiddleware will need adjustment.
# The `Broker` code passes `endpoint` as metadata. These are `ActionEndpoint` or `EventEndpoint` instances.
# These endpoints do have a `name` attribute. So this part is fine.
# The `Service` class is used for type hinting, and its import from `pylecular.service` is assumed to be correct.
# `Context` from `pylecular.context` is also assumed.
# The `broker_instance` fixture is simplified; for tests involving broker start/stop lifecycle hooks,
# it would need to `await broker.start()` and `await broker.stop()` with `yield`.
# The current tests for middleware registration don't require a started broker.
# The test `test_broker_fixture_works` does a basic start/stop.
# Final check of `local_action` and `remote_action`: if `res` is not a dict, the modification is skipped.
# This is reasonable. If a specific test expects modification of non-dict results, the middleware or test needs to be adapted.
# `hasattr(res, '__setitem__')` was an attempt to be more flexible but `isinstance(res, dict)` is safer if action handlers primarily return dicts.
# Reverted to `isinstance(res, dict)` for simplicity as per original example.
