createStubInThreadContextClassLoader

public static Class<?> createStubInThreadContextClassLoader(String className,
                                                            Class<?> aClass)

Creates a test implementation or subclass of a given class with a specified name in the current thread context class-loader. Note that the base class must be accessible from the context class-loader, and if not an interface, must have a public no-arg constructor. Note: Only the class name portion of the name will be used; the package will be computed by SimpleStub, due to JDK restrictions. If an existing class with the same name has been created for a different base class, an exception will be thrown.

Parameters:

className - the name to use for the created class.

aClass - a base class or interface to use as a parent for the specified class.

Returns:

the created stub.
