public final class MockClassLoader
extends DeferSupportingClassLoader

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

classesToMock - The classes that must be modified to prepare for testability.

packagesToDefer - Classes in these packages will be defered to the system class-loader.

MockClassLoader

public MockClassLoader(java.lang.String[] classesToMock)

Creates a new instance of the MockClassLoader based on the following parameters:

Parameters:

classesToMock - The classes that must be modified to prepare for testability.

Method Detail

addClassesToModify

public void addClassesToModify(java.lang.String... classes)

Parameters:

classes - The fully qualified name of the classes that will be appended to the list of classes that will be byte-code modified to enable testability.
