Coverage tests with Hansel

The add tests of your test in one way, you can/should extend your test suite with a coverage test. This is whare the hansel framework comes in. Also see the sheets.

To be able to use the Hansel package, you need to include the hansel.jar and bcel.jar files to the class path. As it has been put (by me) in the /usr/share/java directory, it is automatically included in the java classpath if you use this ant build.xml file. The TestCoverage class could be modelled like this one: shop.ShoppingTestCoverage.java To be able to use hansel under eclipse you must do the following:

• Add hansel.jar to the classpath. It is located under /usr/share/java on our linux boxes.
• Add bcel.jar to the classpath. It is located under /usr/share/java on our linux boxes. bcel is the byte code engineering library, that is used by hansel to 'instrument' the code under test with 'execution tracepoints'.
• If, like me, you use java 5 AND you use locale generic variables (like Entry<Item,Integer>entry=...) then you must turn off a few debugging flags in eclipse. I think it is the classname attribute debug flag or something simmilar. This is a problem in java 5 with this kind of debugging, because the same happens with normal debugging on and building/testing under ant.
