Nigel Daley commented on MAPREDUCE-1050:
----------------------------------------

+1.  We should explore the utility of dynamic mocks, like those produced by http://easymock.org/ or http://jmock.org/ as well as what static mocks need to be built.

> 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.
