Examples of org.powermock.core.classloader.MockClassLoader

org.powermock.core.classloader.MockClassLoader
Mock all classes except system classes.
Notice that there are two different types of classes that are not mocked:
1. system classes are deferred to another classloader
2. testing framework classes are loaded, but not modified
