Integration tests for procedural software can be designed using a black
or white box approach. Both are recommended. Some unit tests can be
reused. Since many errors occur at module interfaces, test designers need
to focus on exercising all input/output parameter pairs, and all calling
relationships. The tester needs to insure the parameters are of the correct
type and in the correct order. The author has had the personal experience
of spending many hours trying to locate a fault that was due to an incorrect

ordering of parameters in the calling routine. The tester must also

insure that once the parameters are passed to a routine they are used
correctly.
