Clean the mess with XStream
Writing clean, isolated and efficient unit test is often a challenge for developers. Efficient test should cover all the possible business scenarios. To create test for covering multiple test scenarios, you need more test data.
For instance, imagine you are writing a test for some Service component. Now if the responsibility of this service is to just collect some data from DAO Layer and pass it on to Business Delegate, life is easy. You can create a mock for DAO using frameworks like EasyMock and you are done. But that’s not often the case. For testing services with complex business logic, its not sufficient to return dummy data. In this case, we create the expected test data and mock the DAO to return the expected data. If this input seed is a simple object, its few additional lines of code and we are done. But what if the test is dealing with complex data model? Normal practice that I observed amongst developers is some private methods are created deep down the test to generate test data – generateXXX().
