From 3afba42d763e003fd4b4f46cd13615fe611712bf Mon Sep 17 00:00:00 2001 From: "Felix Exner (fexner)" Date: Thu, 31 Oct 2024 13:05:27 +0100 Subject: [PATCH] Fix Hardware spawner and add tests for it (#1759) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Tests for hardware spawner. * Fully support spawning a list of hardware components * Use python3 coverage instead of ros2 run in tests * Actually check component's state after changing it * Update hardware_spawner's user documentation --------- Co-authored-by: Dr. Denis Štogl Co-authored-by: Bence Magyar Co-authored-by: Christoph Fröhlich (cherry picked from commit 5dbd6d55c60dd6ad8d0244dca900e9a52f5b3c25) # Conflicts: # controller_manager/CMakeLists.txt --- controller_manager/CMakeLists.txt | 15 + .../controller_manager/hardware_spawner.py | 70 ++--- controller_manager/doc/userdoc.rst | 10 +- .../test/test_hardware_spawner.cpp | 282 ++++++++++++++++++ 4 files changed, 339 insertions(+), 38 deletions(-) create mode 100644 controller_manager/test/test_hardware_spawner.cpp diff --git a/controller_manager/CMakeLists.txt b/controller_manager/CMakeLists.txt index 312f5761a8..d4b6eb5b3b 100644 --- a/controller_manager/CMakeLists.txt +++ b/controller_manager/CMakeLists.txt @@ -190,6 +190,21 @@ if(BUILD_TESTING) ros2_control_test_assets::ros2_control_test_assets ) +<<<<<<< HEAD +======= + ament_add_gmock(test_hardware_spawner + test/test_hardware_spawner + TIMEOUT 120 + ) + target_link_libraries(test_hardware_spawner + controller_manager + ros2_control_test_assets::ros2_control_test_assets + ) + + install(FILES test/test_controller_spawner_with_fallback_controllers.yaml + DESTINATION test) + +>>>>>>> 5dbd6d5 (Fix Hardware spawner and add tests for it (#1759)) install(FILES test/test_controller_spawner_with_type.yaml DESTINATION test) diff --git a/controller_manager/controller_manager/hardware_spawner.py b/controller_manager/controller_manager/hardware_spawner.py index 29c0b5e97c..323e02584a 100644 --- a/controller_manager/controller_manager/hardware_spawner.py +++ b/controller_manager/controller_manager/hardware_spawner.py @@ -57,7 +57,7 @@ def has_service_names(node, node_name, node_namespace, service_names): def is_hardware_component_loaded( node, controller_manager, hardware_component, service_timeout=0.0 ): - components = list_hardware_components(node, hardware_component, service_timeout).component + components = list_hardware_components(node, controller_manager, service_timeout).component return any(c.name == hardware_component for c in components) @@ -82,34 +82,33 @@ def handle_set_component_state_service_call( ) -def activate_components(node, controller_manager_name, components_to_activate): +def activate_component(node, controller_manager_name, component_to_activate): active_state = State() active_state.id = State.PRIMARY_STATE_ACTIVE active_state.label = "active" - for component in components_to_activate: - handle_set_component_state_service_call( - node, controller_manager_name, component, active_state, "activated" - ) + handle_set_component_state_service_call( + node, controller_manager_name, component_to_activate, active_state, "activated" + ) -def configure_components(node, controller_manager_name, components_to_configure): +def configure_component(node, controller_manager_name, component_to_configure): inactive_state = State() inactive_state.id = State.PRIMARY_STATE_INACTIVE inactive_state.label = "inactive" - for component in components_to_configure: - handle_set_component_state_service_call( - node, controller_manager_name, component, inactive_state, "configured" - ) + handle_set_component_state_service_call( + node, controller_manager_name, component_to_configure, inactive_state, "configured" + ) def main(args=None): rclpy.init(args=args, signal_handler_options=SignalHandlerOptions.NO) parser = argparse.ArgumentParser() - activate_or_confiigure_grp = parser.add_mutually_exclusive_group(required=True) + activate_or_configure_grp = parser.add_mutually_exclusive_group(required=True) parser.add_argument( - "hardware_component_name", - help="The name of the hardware component which should be activated.", + "hardware_component_names", + help="The name of the hardware components which should be activated.", + nargs="+", ) parser.add_argument( "-c", @@ -126,13 +125,13 @@ def main(args=None): type=float, ) # add arguments which are mutually exclusive - activate_or_confiigure_grp.add_argument( + activate_or_configure_grp.add_argument( "--activate", help="Activates the given components.
