In MSN, I met my old brother (Chen56) learned that recently resigned at home, and put it on SF.NET.
Himock http://himock.sourceforge.net/
I used to understand some of TDD, practiced several times, I feel very good; but Mock Objects's concept is still listening to -_-!
Search Mo, found this concept on XP2000:
Endo Testing: Unit Testing with Mock Objects
Unit testing is the testing of software units in isolation. However, most units do not work alone, but they collaborate with other units. To test a unit in isolation, we have to simulate the collaborators in the test.Mock Objects are test-oriented Replacements for collaborators.
Currently MO project also has easymock, JMOCK
Very interested, recently intended to study; and promise the old brother to do this open source document internationalization
A good opportunity to learn and exercise
