Class DataStub

  • All Implemented Interfaces:
    Settings, CodeUnit, Data, MemBuffer
    public class DataStub
extends java.lang.Object
implements Data
    DataStub can be extended for use by tests. It throws an UnsupportedOperationException for all methods in the Data interface. Any method that is needed for your test can then be overridden so it can provide its own test implementation and return value.
