core/src/test/scala/integration/kafka/api/ConsumerTest.scala <https://reviews.apache.org/r/27799/#comment114158> I tried this and I don't think that is correct. @Test was introduced in junit4. Adding @Test to methods in ConsumerTest which extends stuff based on junit3 and changing their name to something that doesn't begin with testXXX causes them not to run. So the annotations have no effect, but look like they should, which is what I think is confusing. Here is what I think we could agree on: let's get off junit3 entirely, I think the mixture of both is error prone. core/src/test/scala/integration/kafka/api/ConsumerTest.scala <https://reviews.apache.org/r/27799/#comment114165> Yeah it might be good to consider doing a multithreaded test with multiple consumers and producers once we have the group management stuff. I guess the argument for why this would be different from the producer is that the consumer itself is single-threaded so there is no background work happening. The real weakness I felt in these tests is that they only cover graceful shutdown. Actual machine death would I think expose a ton of issues. But we can probably do this in the system tests... core/src/test/scala/integration/kafka/api/ConsumerTest.scala <https://reviews.apache.org/r/27799/#comment114169> Can't you just run it in the ide and immediately debug and see what is happening? That also takes only a few secs whereas the full test run is slow.... Anyhow I'll fix this case but I think we have this issue in about 1000 places and fixing it is quite ugly (see the fixed code I'm about to post) and obscures what is going on. Also fixing it with a timeout is far worse since then you have a timing assumption that will randomly fail. - Jay Kreps On Jan. 23, 2015, 4:22 a.m., Jay Kreps wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
