Subject [jira] [Commented] (HADOOP-14178) Move Mockito up to version 2.x
Date Thu, 16 Mar 2017 04:24:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15927465#comment-15927465

Akira Ajisaka commented on HADOOP-14178:
----------------------------------------

The upgrade will be very big change, so I'd like to split this into some sub-tasks to reduce
the cost of review. The first sub-task is to remove the usage of Whitebox, which was removed
in Mockito 2.1. I'll add sub-tasks later if needed.

> I don't know when Hadoop picked up Mockito, but it has been frozen at 1.8.5 since the
switch to maven in 2011. 
> Mockito is now at version 2.1, [with lots of Java 8 support|https://github.com/mockito/mockito/wiki/What%27s-new-in-Mockito-2].
That' s not just defining actions as closures, but in supporting Optional types, mocking methods
in interfaces, etc. 
> It's only used for testing, and, *provided there aren't regressions*, cost of upgrade
is low. The good news: test tools usually come with good test coverage. The bad: mockito does
go deep into java bytecodes.
