HCCL LLT【免费下载链接】hcommHCOMMHuawei Communication是HCCL的通信基础库提供通信域以及通信资源的管理能力。项目地址: https://gitcode.com/cann/hcommOverviewHCCL LLT (Low Level Test) is the test framework for HCCL, designed to systematically verify the functional completeness and performance stability of HCCL components at all levels. LLT covers multiple parts of HCCL including the algorithm layer, framework layer, platform layer, and external interface layer. Through comprehensive test cases, it ensures the reliability and efficiency of HCCL in various business scenarios.Directory Structuretest/ ├── legacy # Historical version compatibility test framework │ ├── common # Common utilities │ ├── depends # Test dependencies on other component headers │ ├── st # ST integration test cases │ │ ├── algorithm # Communication algorithm test cases │ │ ├── fwk # Communication framework test cases │ │ ├── service # Service layer test cases │ │ └── test_case # Test cases │ └── ut # UT integration test cases │ ├── aicpu # AICPU-specific test cases │ ├── all_source_code # Source code file paths │ ├── common # Common utilities │ ├── framework # Communication framework test cases │ ├── service # Service layer test cases │ └── unified_platform # Unified platform layer test cases ├── st/algorithm # ST integration test cases (algorithm analyzer) │ ├── testcase # Test cases │ └── utils # Common utilities └── ut # UT unit test cases ├── aicpu_kfc # MC2-related tests ├── common # Common utilities ├── depends # Test dependencies on other component headers ├── device # Device tests ├── framework # Communication framework test cases ├── impl # Communication algorithm implementation test cases ├── inter # Interface adaptation layer test cases ├── misc # Miscellaneous test cases ├── platform # Communication platform implementation test cases └── stub # Test stub functionsBuild and RunExecute the following commands from the repository root directory:# Build and run all unit test cases bash build.sh --ut # Build and run all integration test cases bash build.sh --st # Build and run individual test suite cases bash build.sh --open_hccl_test bash build.sh --executor_hccl_test bash build.sh --executor_reduce_hccl_test bash build.sh --executor_pipeline_hccl_test # Manually execute test cases ./build/test/st/algorithm/testcase/testcase/open_hccl_test ./build/test/st/algorithm/testcase/testcase/executor_hccl_test ./build/test/st/algorithm/testcase/testcase/executor_reduce_hccl_test ./build/test/st/algorithm/testcase/testcase/executor_pipeline_hccl_testExecutable Output LocationAll executables are output to thebuild/testdirectory by default. The path can be adjusted by modifyingCMakeLists.txt:set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${HCCL_OPEN_CODE_ROOT}/build/test) set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${HCCL_OPEN_CODE_ROOT}/build/test)How to Write Test CasesHCCL LLT test cases are implemented using the Google Test framework. For detailed writing guidelines, refer to the Google Test User Guide.Select the appropriate directory based on the test target, e.g.,test/algorithmortest/frameworkCreate a new test class based on Google TestUpdate the corresponding directorysCMakeLists.txtto add the test entryExample test code:#include gtest/gtest.h TEST(MyTestClass, MyTestCase) { // Implement assertion logic EXPECT_EQ(actual_value, expected_value); }How to Run Specific Test CasesTo run specific test cases individually, refer to the Google Test User Guide and add the--gtest_filterparameter when executing the test.Usinghccl_utest_framework_op_base_apias an example:# Run only test cases of the HcclCommInitRootInfoTest test class ./build/test/hccl_utest_framework_op_base_api --gtest_filterHcclCommInitRootInfoTest.*【免费下载链接】hcommHCOMMHuawei Communication是HCCL的通信基础库提供通信域以及通信资源的管理能力。项目地址: https://gitcode.com/cann/hcomm创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
