Mock objects is a test-first driven framework for building generic software and/or unit testing frameworks. it supports:
* a methodology for developing and using mock objects.
* a core mock object framework. this is a library of code that
supports the implementation of mock objects, based around a
set of expectation classes for values and collections. there are
also various other classes to make mock objects easier to write
or to use.
* a default set of mock implementations for the standard java
platform apis. we have made a start on packages such as servlets, sql,
and io.
