Task: Create Support Software (DT)

In order to execute the testing of a unit or an integration step satisfactorily, it is necessary in a number of cases to create stubs (also known as mock objects) or drivers. The stubs replace units that are called by the units to be tested. The drivers create units that call the units to be tested. The communication between the units to be tested and the stubs and drivers takes place by means of an interface. The stubs and drivers should be such that these interfaces contain realistic values and correspond with the eventual, actual interfaces between the various units. Of course, the stubs and drivers themselves are also subjected to testing.
