Description

LinuxMemoryMeasurementTestFixture.TestPublishMetricsMessage is flaky

Expected Behavior

The test should always succeed.

Actual Behavior

The test sometimes fail because it relies on having messages processed "fast enough". This has been reported in an ASAN build, most likely due to the fact that ASAN builds are slower than normal builds.

To Reproduce

Run:

./test_linux_memory_measurement_node --gtest_repeat=99999999

Wait until it starts failing. On fast workstations, buildling with ASAN enabled may be necessary to slow-down the execution enough to exhibit the bug.

System (please complete the following information)

  • OS: Bionic
  • ROS2 Distro: master

Additional context

To make this bug reliable, each step in the test needs to wait until the ROS messages are actually processed. The callback may switch a std::atomic_bool or a std::atomic_flag for instance. Blocking until the lifecycle API starts reporting the new state may also be another possibility.

If waiting for messages to be processed is not enough, we should explore whether cache coherency could play a role in this bug.

This assertion is failing:

system_metrics_collector/system_metrics_collector/test/system_metrics_collector/test_linux_memory_measurement.cpp

Line 275 in 3f989ca

EXPECT_DOUBLE_EQ(expected_stat.at(stat.data_type), stat.data);

This test needs to be modified to remove kTestDuration, we should spin until a premise is satisfied instead.

I'm also a bit concerned w.r.t. cache coherency, making expected_stats_ const would solve this. times_received_ should be protected with a mutex.

Rather than add the complexity testing for message publication in the unit tests, see this PR #98 which adds a test to check for multiple received messages.

To fix the failures here, your comments are still valid when attempting to receive a single message and check its contents. I would expect the tests to fail in the LinuxProcessCpuMeasurementTestFixture as well, as they also fail here: #83
