It means one of the tests defined here is failing:
https://github.com/apache/qpid/blob/trunk/qpid/cpp/src/tests/interop_tests.py You should first determine which one is failing. Use the following command to run the test verbosely: ctest -R '^interop_tests$' -VV And then see what it says. Test failures are often environment dependent, so the output may point out something you can change locally. Or of course it may be a real test failure. https://github.com/apache/qpid/blob/trunk/qpid/cpp/src/tests/README.txt Justin On Tue, Mar 8, 2016 at 7:23 AM, Flores, Paul A. <paul.a.flo...@saic.com> wrote: > How do I resolve the single failing test; interop_test? > > > > More so what does this test failure mean? > > > > Any help is appreciated! >
