Domain and Interface Testing

Integration testing is a process of testing the correctness of the interface between two correct components
Components A and B have been demonstrated to satisfy their component test, and as part of the act of integrating them we want to investigate possible inconsistencies across their interface
Interface between any two components is considered as a subroutine call
We are looking for bugs in that "call" when we do interface testing
Let's assume that the call sequence is correct and that there are no type incompatibilities

For a single variable, the domain span is the set of the smallest and the largest values and the numbers which lie between them. For every input variable we want (at least): compatible domain spans and compatible closures (Compatible but need not be equal)
The domain of the calling function should be compatible with the domain of the called function
Example: If the domain of the calling function for a variable is 0 to 100, the domain of the called function should also be same (at least compatible) so that the integration is trouble .
