The verify method takes all of the mock objects that were created as parameters, similar to the replay method. EasyMock is a framework for creating mock objects using the java.
So I don’t see how eaymock could change things.
Make private methods protected in cases where you want to control access and yet still access the method for testing. The replay method is called to make the Mock object available.

The timeout parameter specifies in milliseconds how long esaymock allow a single test to run. Due to EasyMock’s unique style of recording expectations, most refactorings will not affect the Mock Objects. These methods are executed once per test class instead of once per test method as setUp and tearDown arebefore and after respectively.
