EasyMock 101
A 30 Minute Review by Matthew McCullough

❶ What Is Mocking?

Are You Mocking Me?
• A fake object
• Allows for more modular testing
• Records and verifies expectations of calls

❷ Creating A Mock

IEnumeration iEnumIntfMock =
EasyMock.createMock(EnumeratedAttribute.class);

❸ Expectations

Expecting A Lot
• Expect method is called on mock
• Expect sequence of method calls on mock
(call createStrictMock())
• Expect parameters to methods calls on
mock

Expect A Call
EasyMock.expect(iEnumIntfMock.getNumberOfRows()
);

Expect A Return
EasyMock.expect(iEnumIntfMock.getNumberOfRows()
).andReturn(5);
