To better understand the reflection api , I was using
java.lang.reflect.* for creation of junit skeleton on the go and later discovered there is a similar stuff which creates the junit structure and the suites for the specified package called JUNITDOCLET.
Following is the build.xml used for creation of junit classes and the suites for the classes under package com.abc.dummy and can be specified as com.abc.*.It takes care of all the lifecycle methods of junit. This JunitDoclet is most handy when the classes have more number of method and it supports 3.x and 4.x versions of junit depending on the Junitdoclet jar in the buildpath ;-)
