EasyMock Ports to .Net

• Rhino.Mocks was created by Oren Eini and is a rollout from EasyMock.NET. It is still actively supported
• EasyMock.NET was developped by Marco Struck and Matthias Jantz from MSBK Proximity. It was the first port of EasyMock to .Net. However, this project doesn't seem supported anymore.

Mock Objects in General

• http://www.mockobjects.com
  contains a lot of Mock Object-related information.
• http://www.michaelminella.com/testing/the-concept-of-mocking.html
  Some information on the concept of mocking.

EasyMock Alternatives and Add-ins

• Powermock is built on top of EasyMock. It 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.
• easymock-propertyutils is an add-in to EasyMock. It allows to use JavaBeans-style property matching for arguments when using EasyMock. Property matching is based on commons-beanutils as documented in Standard JavaBeans.
• jMock is another dynamic Mock Object generator for Java that was first released two years after EasyMock. It uses another approach to define expectations that results in more flexibility to set expectations (you may specify almost everything imaginable) at the cost of less flexibility when refactoring (refactorings like method renaming and parameter reordering will break the tests) and loss of code completion when defining expectations or test-driving code.
• Mockito is a lot like EasyMock but ordering steps a little differently. Mockito doesn't understand the notion of 'expectation'. There is only stubbing and verifications.
• Hamcrest is a library of matcher objects that can be used with EasyMock.
