Subject [jira] [Updated] (MRUNIT-180) Being able to use a comparator on runTest
Date Mon, 11 Mar 2013 16:09:18 GMT

     [ https://issues.apache.org/jira/browse/MRUNIT-180?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ximo Guanter updated MRUNIT-180:
--------------------------------

    Description: 
Sometimes using withOutput and runTest is not possible if the .equals method is not the correct
way to compare equality. This is especially true for Mapper and Reducers that return doubles
or structure with doubles in them, since there is no way to specify a desired error tolerance
for the result.

Being able to specify a Comparator for the key and value types enabled the usage of runTest
for these cases.
