unit testing - When running make check on Mesos one of the tests fails, what now? -


after running make check when building mesos, found 1 of tests failing. how can find out more reasoning behind failure?

note make check needs run before following can used make check renders needed binaries.

the following assumes current directory (pwd) build folder within extracted / cloned mesos project directory structure.

let's assume test named foo.bar had failed you. go ahead , run test individually, enhanced output:

./bin/mesos-tests.sh --gtest_filter="foo.bar" --verbose

that should reveal more insights of failure reasoning.

in cases above still has little output understand problem, rare cases, beneficial increase verbosity further.

glog_v=2 ./bin/mesos-tests.sh --gtest_filter="foo.bar" --verbose

that enable common vlog levels of mesos. not meant users developers. don't expect output user friendly.
