"copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Wed, 11 Feb 2026 00:21:04 +0000 Subject: [PATCH 003/132] Convert mp_unit tests from gtest to framework.hpp - Modified test/mp_unit/mp_unit_tests.hpp to use ../framework.hpp instead of gtest/gtest.h - Enhanced test/framework.hpp with GTest-compatible APIs: - Added Environment base class for global test setup/teardown - Added TestInfo and UnitTest classes for test metadata access - Added GTEST_SKIP macro support via SkipHelper class - Added namespace alias 'testing' for compatibility - Added InitGoogleTest and AddGlobalTestEnvironment helper functions - Updated test/framework.cc with implementations for new classes - All mp_unit test files now use framework.hpp through mp_unit_tests.hpp - Formatting applied

Add nlohmann::ordered_json metrics field to TestResult struct - Add nlohmann/json.hpp include to test/framework.hpp - Link test_framework with nlohmann_json::nlohmann_json - Replace PerfTestResult with TestResult in test/perf/framework.cc - Move perf utility functions to utils namespace for consistency - Remove duplicate PerfTestResult struct definition This consolidates the two similar structs into one, reducing code duplication while maintaining all necessary fields for both unit tests (passed/failure_message) and performance tests (metrics).

Remove test/perf/ directory (fifo_test.cu, framework.{cc,hpp}, CMakeLists.txt) - Remove add_subdirectory(perf) from test/CMakeLists.txt - Performance tests now integrated into unit_tests as fifo_perf_tests.cu - Fix mp_unit_tests.cc to use framework functions without ::testing:: namespace - Fix bootstrap_tests.cc ErrorCode comparison to use ASSERT_TRUE - Fix switch_channel_tests.cu to not use streaming with ASSERT_EQ - Add missing #include to executor_tests.cc All perf test functionality is now in unit_tests and can be filtered with --exclude-perf-tests flag. The standalone test/perf/ directory is no longer needed.

Add missing includes to fifo_perf_tests.cu - Add #include - Add #include 2. Fix license header capitalization (4 files) - "license." → "License." in test/framework.{hpp,cc} - "license." → "License." in test/unit/{unit_tests_main.cc,fifo_perf_tests.cu} 3. Fix double MPI_Init issue - Check MPI_Initialized() before calling MPI_Init - Prevents double initialization when mp_unit_tests already inits MPI 4. Fix coverage flags for CUDA compilation - Use generator expressions to apply --coverage only to C++ language - Prevents breaking CUDA compilation with host-only flags 5. Fix environment memory leak - Delete environment objects after TearDown() - Clear environments_ vector 6. Implement proper GTEST_SKIP handling - Create SkipException class - Handle skipped tests separately from failures - Report skipped test count 7. Implement GTest-style filter pattern matching - Support wildcards (* and ?) - Support negative patterns (-Pattern) - Support colon-separated patterns (Foo:Bar) - Compatible with existing CI usage like --gtest_filter=-*Ib* Verified builds successfully with Docker.

Ensure TearDown() is always called if SetUp() succeeds, even when TestBody() throws. This prevents resource leaks and maintains MPI synchronization between tests. 2. Replace assert() in fifo_perf_tests.cu with proper return false on validation failure, ensuring consistent test failure reporting.

Add TEST_DATA_SEND_RECV verifier kernel that replays fill_data PRNG with peer_rank seed to validate received data - Add double-buffer support for sendrecv in executor_test.py: allocate 2 input/result/test buffers, alternate per iteration - Create two executor funcs for sendrecv, one per buffer pair - Update bench_correctness and bench_time to handle double-buffer - Add bandwidth reporting to output Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- python/test/executor_test.py | 123 ++++++++++------ python/test/executor_test_verifier.cu | 201 ++------------------------ 2 files changed, 90 insertions(+), 234 deletions(-) diff --git a/python/test/executor_test.py b/python/test/executor_test.py index 1175d6298..be6e5834c 100644 --- a/python/test/executor_test.py +++ b/python/test/executor_test.py @@ -14,6 +14,7 @@ from mscclpp.utils import KernelBuilder, pack import os import struct +from typing import Callable, Union import cupy as cp from mpi4py import MPI @@ -32,13 +33,16 @@ def parse_dtype(dtype_str): raise ValueError(f"Unknown data type: {dtype_str}") -def bench_time(n_iters: int, n_graph_iters: int, func): -
