To set up the expectations you call methods on the mock and thats it. Connect the mock with the object being unit tested. 2. The difference between fakes and mocks will become much clearer once you start to use mocks. Mock objects purpose is to test code in isolation from the rest of the code; they replace the real objects with which your code under test collaborates. The easymock object conforms perfectly to the TaxRateManager interface, but when used in conjunction with static methods on EasyMock, it can do ever so much more. In this line while (sc.nextLine() == "" || sc.nextLine().isEmpty()) you are basically reading a line from the scanner, comparing it (*) with "", then forgetting it, because you read the next line again.
