AWS unit test fails

[jace-bevo]

We are using AWS C++ SDK 1.9.160. It builds fine before but recently we need to rebuild it on Linux (Ubuntu 20.04) we get one unit test error in HttpClientTest.TestRandomURLMultiThreaded.
This is a snipped of the test output during the build:

-- Detecting C compile features - done

We cannot complete the build due to this error.
What can be the cause? Should we upgrade to new version?
Is there a way to disable some particular unit test or tell it not to quit?

You can disable unit tests by adding this cmake command: -DENABLE_TESTING=OFF

I would always recommend using the latest version of this sdk, and upgrading it might resolve the unit tests failing.

I had this issue and worked around it by increasing the timeout value here:
https://github.com/aws/aws-sdk-cpp/blob/main/aws-cpp-sdk-core-tests/http/HttpClientTest.cpp#L113

const int timeoutSecs = 5;

The default of 5 secs might not be enough for some systems.
Hope this helps someone.
