public class TestCaseClassLoader

extends java.lang.ClassLoader

A custom class loader which enables the reloading of classes for each test run. The class loader can be configured with a list of package paths that should be excluded from loading. The loading of these packages is delegated to the system class loader. They will be shared across test runs.

The list of excluded package paths is specified in a properties file "excluded.properties" that is located in the same place as the TestCaseClassLoader class.

Known limitation: the TestCaseClassLoader cannot load classes from jar files.
