From b31794b95dce2d78418144d6c46aaf889c9b651d Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Wed, 29 Apr 2026 22:09:54 +0000 Subject: [PATCH 1/3] feat(events): add close() tests for ReactiveEventBus to complete RxPY subject lifecycle This adds BDD scenario tests for the ReactiveEventBus.close() method which was recently introduced to complete the RxPY Subject lifecycle. Tests covered: - close() terminates the reactive stream and clears subscriptions - close() clears the in-memory audit log Also includes: - @when('I close the ReactiveEventBus') step definition - @then('the subscribed handler should have received') step for post-close verification - @then('the subscriptions should be cleared') assertion step - @then('the audit log should be empty') assertion step Closes #10916 ISSUES CLOSED: #10916 --- add_close_steps.py | 59 +++++++++++++++++++++++++++++++ features/event_bus.feature | 20 +++++++++++ features/steps/event_bus_steps.py | 31 ++++++++++++++++ 3 files changed, 110 insertions(+) create mode 100644 add_close_steps.py diff --git a/add_close_steps.py b/add_close_steps.py new file mode 100644 index 000000000..d4d4c95e1 --- /dev/null +++ b/add_close_steps.py @@ -0,0 +1,59 @@ +import pathlib + +steps = pathlib.Path('/tmp/task-implementor-1748611200/repo/features/steps/event_bus_steps.py') +content = steps.read_text() + +marker = '@then("the EventBus Protocol stubs should be callable")' + +new_block = """ +# --------------------------------------------------------------------------- +# ReactiveEventBus close() steps +# --------------------------------------------------------------------------- + + +@when("I close the ReactiveEventBus") +def step_close_reactive_bus(ctx: Context) -> None: + """Close the ReactiveEventBus to release RxPY Subject resources.""" + ctx.bus.close() + + +@then("the subscribed handler should have received {n:d} event") +def step_subscribed_handler_received(ctx: Context, n: int) -> None: + """Verify handler received expected count even after close.""" + assert ctx.collectors, "No collectors registered" + count = len(ctx.collectors[0].received) + assert count == n, f"Expected {n} events, got {count}" + + +@then("the subscriptions should be cleared") +def step_subscriptions_cleared(ctx: Context) -> None: + """Verify that close() emptied all subscriptions.""" + assert len(ctx.bus._subscriptions) == 0, ( + f"Expected no subscriptions after close, found {len(ctx.bus._subscriptions)}" + ) + + +@then("the audit log should be empty") +def step_audit_log_empty(ctx: Context) -> None: + """Verify that close() cleared the audit log.""" + assert len(ctx.bus.audit_log) == 0, ( + f"Expected empty audit log after close, found {len(ctx.bus.audit_log)} events" + ) + +""" + +if marker not in content: + print(f"ERROR: marker not found in file") + import sys + sys.exit(1) + +new_full = content.replace(marker, new_block + marker, 1) +steps.write_text(new_full) +print('Step definitions inserted successfully') + +# Verify +assert 'step_close_reactive_bus' in new_full +assert 'step_subscriptions_cleared' in new_full +assert 'step_audit_log_empty' in new_full +assert 'step_subscribed_handler_received' in new_full +print('All step definitions verified present in file') diff --git a/features/event_bus.feature b/features/event_bus.feature index 2875b4f58..33b48bb8b 100644 --- a/features/event_bus.feature +++ b/features/event_bus.feature @@ -119,6 +119,26 @@ Feature: EventBus protocol and domain event emission Then the EventBus Protocol stubs should be callable # --------------------------------------------------------------------------- + + # --------------------------------------------------------------------------- + # ReactiveEventBus close() -
