Just found out about it. Info can be found at http://groups.google.com/group/Brisbane-XP . I’ve been involved in some part in 2 previous groups in Brisbane. I’m thinking about some ideas myself, I’ve got all the XP skills, however I’m now skilling up in Spring (a full-stack Java/J2EE application framework) and Hibernate (a powerful, ultra-high performance object/relational persistence and query service for Java). https://ronaldbradford.com/blog/junit-40-is-getting-nearer-2005-12-01/ Thu, 01 Dec 2005 14:46:42 +0000 https://ronaldbradford.com/blog/junit-40-is-getting-nearer-2005-12-01/ For those Agile developers out there, JUnit requires no explaination.
