This approach: - Uses actual driver_super.c implementation via HAL mocks - Tests the complete frame analysis flow end-to-end - Validates both fixed-length and variable-length frame parsing Key changes: - Add driver_super_mock_prelude.h for force-include trick - Extend HAL mock with append_rx_data and set_rx_chunk_size - Add mock headers for library/system/src_user dependencies - Update CMakeLists.txt to apply prelude to test compilation - Simplify test_stream_rec_buffer.cpp declarations Co-Authored-By: Claude Opus 4.5 --- component_driver/tests/CMakeLists.txt | 23 + .../tests/mocks/driver_super_mock_prelude.h | 164 +++ component_driver/tests/mocks/library/endian.h | 56 + component_driver/tests/mocks/library/print.h | 23 + .../tests/mocks/mock_hal_handler_registry.c | 21 + .../tests/mocks/mock_hal_handler_registry.h | 2 + .../component_driver/driver_super_params.h | 10 + .../component_driver/hal_handler_registry.h | 15 + .../mocks/system/time_manager/time_manager.h | 10 + .../common_packet/common_cmd_packet_util.h | 10 + .../tests/test_frame_analysis.cpp | 1047 +++++------------ .../tests/test_stream_rec_buffer.cpp | 161 +-- 12 files changed, 668 insertions(+), 874 deletions(-) create mode 100644 component_driver/tests/mocks/driver_super_mock_prelude.h create mode 100644 component_driver/tests/mocks/library/endian.h create mode 100644 component_driver/tests/mocks/library/print.h create mode 100644 component_driver/tests/mocks/src_user/settings/component_driver/driver_super_params.h create mode 100644 component_driver/tests/mocks/src_user/settings/component_driver/hal_handler_registry.h create mode 100644 component_driver/tests/mocks/system/time_manager/time_manager.h create mode 100644 component_driver/tests/mocks/tlm_cmd/common_packet/common_cmd_packet_util.h diff --git a/component_driver/tests/CMakeLists.txt b/component_driver/tests/CMakeLists.txt index aca6bf6bf..adbe4a56a 100644 --- a/component_driver/tests/CMakeLists.txt +++ b/component_driver/tests/CMakeLists.txt @@ -15,14 +15,26 @@ FetchContent_MakeAvailable(googletest) enable_testing() +set(MOCK_PRELUDE_FLAG "-include ${CMAKE_CURRENT_SOURCE_DIR}/mocks/driver_super_mock_prelude.h") + # StreamRecBuffer のテスト add_executable(test_stream_rec_buffer test_stream_rec_buffer.cpp + ${CMAKE_CURRENT_SOURCE_DIR}/../driver_super.c mocks/mock_hal_handler_registry.c mocks/mock_time_manager.c ) +# driver_super.c にモック prelude を適用（test_stream_rec_buffer 用） +set_source_files_properties( + ${CMAKE_CURRENT_SOURCE_DIR}/../driver_super.c + TARGET_DIRECTORY test_stream_rec_buffer + PROPERTIES COMPILE_FLAGS "${MOCK_PRELUDE_FLAG}" +) + target_include_directories(test_stream_rec_buffer PRIVATE + ${CMAKE_CURRENT_SOURCE_DIR}/mocks # モックが実際のヘッダより優先される + ${CMAKE_CURRENT_SOURCE_DIR}/mocks/src_user # インクルード用 ${CMAKE_CURRENT_SOURCE_DIR} ${CMAKE_CURRENT_SOURCE_DIR}/.. ${CMAKE_CURRENT_SOURCE_DIR}/../.. @@ -38,11 +50,22 @@ gtest_discover_tests(test_stream_rec_buffer) # FrameAnalysis のテスト add_executable(test_frame_analysis test_frame_analysis.cpp + ${CMAKE_CURRENT_SOURCE_DIR}/../driver_super.c mocks/mock_hal_handler_registry.c mocks/mock_time_manager.c ) +# driver_super.c と test_frame_analysis.cpp にモック prelude を適用 +set_source_files_properties( + ${CMAKE_CURRENT_SOURCE_DIR}/../driver_super.c + ${CMAKE_CURRENT_SOURCE_DIR}/test_frame_analysis.cpp + TARGET_DIRECTORY test_frame_analysis + PROPERTIES COMPILE_FLAGS "${MOCK_PRELUDE_FLAG}" +) + target_include_directories(test_frame_analysis PRIVATE + ${CMAKE_CURRENT_SOURCE_DIR}/mocks # モックが実際のヘッダより優先される + ${CMAKE_CURRENT_SOURCE_DIR}/mocks/src_user # インクルード用 ${CMAKE_CURRENT_SOURCE_DIR} ${CMAKE_CURRENT_SOURCE_DIR}/.. ${CMAKE_CURRENT_SOURCE_DIR}/../.. diff --git a/component_driver/tests/mocks/driver_super_mock_prelude.h b/component_driver/tests/mocks/driver_super_mock_prelude.h new file mode 100644 index 000000000..6778ecbfe --- /dev/null +++ b/component_driver/tests/mocks/driver_super_mock_prelude.h @@ -0,0 +1,164 @@ +/** + * @file driver_super_mock_prelude.h + * @brief driver_super.c コンパイル用の前処理ヘッダ + * + * -include フラグで driver_super.c より先にインクルードすることで、 + * 実際のヘッダのインクルードガードを設定し、複雑な依存を回避する。 + * + * 注意: このヘッダは driver_super.c のコンパイルにのみ使用する。 + * テストコードは mocks/ 以下のモックファイルを直接インクルードする。 + */ +#ifndef DRIVER_SUPER_MOCK_PRELUDE_H_ +#define DRIVER_SUPER_MOCK_PRELUDE_H_ + +#include +#include +#include + +#ifdef __cplusplus +extern "C" { +#endif + +// ============================================================================= +// obc_time.h のモック +// ============================================================================= +#define OBC_TIME_H_ + +typedef uint32_t cycle_t;
