performance_test_fixture

This repository contains the source code for the performance_test_fixture package.

performance_test_fixture provides:

1. A Google Benchmark fixture that leverages memory tools from osrf_testing_tools_cpp to record memory allocation statistics
2. A CMake macro for compiling, linking, and configuring benchmarking runs, as well as automatically skipping the tests on platforms where the osrf_testing_tools_cpp memory tools are not supported

Usage

The test fixture can be used just like any other Google Benchmark fixture:

#include <performance_test_fixture/performance_test_fixture.hpp>

using performance_test_fixture::PerformanceTest;

BENCHMARK_F(PerformanceTest, example_test)(benchmark::State & st)
{
  ...
}

The CMake macro can be used in the same way as the rest of the ament_cmake_test family of macros:

  find_package(performance_test_fixture REQUIRED)
  add_performance_test(example_test test/example_test.cpp)

Because it has a large impact on performance, trace messages coming from the memory tools in osrf_testing_tools_cpp are suppressed by default. To enable memory operation trace logging, set the environment variable PERFORMANCE_TEST_FIXTURE_ENABLE_TRACE=1.

Changelog for package performance_test_fixture

0.2.1 (2024-09-06)

• Fix a warning when building on Ubuntu Noble. (#26) (#27) In particular, gcc 13.2 was complaining that we were accessing a pointer after a free. And that was technically true; the calls to DoNotOptimize(ptr) were after the free. Just move this before the free (when the ptr is still valid) to remove the warning, but still ensure that we don't optimize the pointer away. (cherry picked from commit e406c3cf4a352ab3f89c43fcebe7503781be5905) Co-authored-by: Chris Lalancette <<clalancette@gmail.com>>
