Subject [jira] Updated: (MAPREDUCE-1050) Introduce a mock object testing framework
Date Thu, 05 Nov 2009 21:03:33 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1050?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Konstantin Boudnik updated MAPREDUCE-1050:
------------------------------------------

    Attachment: MAPREDUCE-1050.patch

Per conversation w/ Nigel and Tom last night, I've moved test cases from {{src/test/mapred/}}
hierarchy to {{src/test/unit/}} for these are true unit tests.

Also, I've created new ant target 'run-test-unit' to execute unit tests only and modified
the test running macro to pickup unit tests when a testcase is specified.

Also, one of the tests 'TestLostTaskTracker' is repeatedly failing now. Tom, could you please
take a look?

> Using mock objects in unit tests can improve code quality (see e.g. http://www.mockobjects.com/).
Hadoop would benefit from having a mock object framework for developers to write unit tests
with. Doing so will allow a wider range of failure conditions to be tested and the tests will
run faster.
