[jira] [Commented] (HADOOP-7537) Add PowerMock for the development of better tests

    [ https://issues.apache.org/jira/browse/HADOOP-7537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16184853#comment-16184853 ] 

Eric Yang commented on HADOOP-7537:
-----------------------------------

Reopening this old issue.  Powermockito is great for creating better unit test cases.  There were some incompatibility issues between Mockito and PowerMock in the last couple years.  Mockito 1.9.5 + Powermock 1.5.6, and commons-io 2.5 seems to be a reliable combination that works for Hadoop trunk code base.

> We already have Mockito, but PowerMock extends its capabilties so that we can mock constructors and static methods. I find that it is extremely difficult, if not impossible, to properly test some of the low-level features without this.
