runTests() should throw meaningful error messages
-------------------------------------------------
Key: MRUNIT-15
URL: https://issues.apache.org/jira/browse/MRUNIT-15
Project: MRUnit
Issue Type: Improvement
Affects Versions: 0.5.0
Reporter: E. Sammer
When runTests() fails to validate the output generated by a mapper or reducer,
it throws a RuntimeException with no message and relies on logging output to
indicate what was wrong. Instead it should throw meaningful exceptions
(although they can still be unchecked).
