Mocking a concrete class using EasyMock

Question

Is it possible? How do I do it?

Answer 1

See the EasyMock Class Extension documentation and download it from the SourceForge project. You can't mock final methods though.

EDIT: This is now part of EasyMock for v3 and above, as noted in comments.

Answer 2

Powermock extends EasyMock and allows you to mock concrete types, even final and static methods.

PowerMock is a framework that extend other mock libraries such as EasyMock with more powerful capabilities. PowerMock uses a custom classloader and bytecode manipulation to enable mocking of static methods, constructors, final classes and methods, private methods, removal of static initializers and more.

Answer 4

EasyMock class extensions have been integrated into EasyMock as of v3.0; see the release notes.

Answer 5

When creating a mock, simply use the org.easymock.classextension version of the EasyMock class. The result will be castable.
