Abraham Fine commented on ZOOKEEPER-2579:
-----------------------------------------
[~eribeiro] Thanks for the feedback.
The reason that I went with the more brittle test that involves checking to see
if the server starts up is because I felt that type of test better verifies the
behavior that I wanted to achieve with this jira. The tests that I wrote verify
that incorrect permissioning prevents the server from starting, as opposed to
just verifying the behavior of the FileTxnLog.
I guess it would be reasonable to say that the tests that I wrote are more like
integration tests while the tests that you attached are true unit tests. I
guess it could be argued that most of the tests in ZooKeeperServerMainTest are
really integration tests.
It would be possible to include both types of test instead of needing to
choose. What do you think?
> ZooKeeper server should verify that dataDir and snapDir are writeable before
