ZePAG has released the first version Usurper, a neat tool for easily creating test instances of your value objects. It is a nice compliment to the classical mocking and stubbing tools.
I warmly invite you to read his post presenting Usurper and then to rush to the tool web site to start benefiting from its goodnesses right away.
And please, do not forget to ask him why he opted for the org.org package root!
