Open greenpau opened 6 years ago

@blp , when working on https://github.com/openvswitch/ovs/pull/230, I received the test error below.

I don't think it is related to my work.

Thanks for the report.

Some of the OVN tests occasionally fail due to races. Do you see this test fail every time you run it? You can run just this test with "make check TESTSUITEFLAGS=2530".

ack.

It was my observation from Travis CI run. I don't run test locally at the moment 😄 so Travis CI is what I have 😅

You can run just this test with "make check TESTSUITEFLAGS=2530".

@blp , good to know 😄 I am new to OVN code base, but I get the relationship! Thank for the awesomeness of OVN! Great piece of software.
