Some development teams copy and paste code from 1 unit test to another to create test data for their testmethod. Then when they need to add a new field because it is a new required field that is failing tests they realise they've got to copy to all classes. Some development teams improve this by having a central class but the functions they make have passed in arguments for each field, so for each field that needs to be passed in requires a change to this class.
Our framework is highly flexible and capable of creating whatever type of test data structures required.
