[jira] [Commented] (STORM-3128) Connection refused error in AsyncLocalizerTest

["Stig Rohde Døssing (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/STORM-3128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16572168#comment-16572168 ] 

Stig Rohde Døssing commented on STORM-3128:
-------------------------------------------

It looks like the test is doing a partial mock of LocalFsBlobStore, where the parts that would be hitting Zookeeper are stubbed. It's kind of an unfortunate way to do this kind of test (partial mocks usually point to the class doing too much), but the test itself looks correct to me. I don't think this points to a bug, it's just that the test probably should have been written differently (and LocalFsBlobStore split up).

> In AsyncLocalizerTest testKeyNotFoundException, a localBlobStore is created and tries but failed to connect to zookeeper due to connection error. I'm not sure if this compromises the test even though it is passed after connection retry timeout. But it's nice to keep in mind.
