As mentioned before, the practical part of this thesis
was a black box test applied on
DPV . Some of this tests will be explained for each tested
module here. Only the implemented features will be
discussed, other weaknesses of the program , like
suboptimal designs -- for instance an update inconsistency in the
table diabetik -- will be ignored, because they
have already been discussed in [Schmid93]. Due to the lack of
correctness checks in a lot of entry fields
, it has also
been refrained from using impossible inputs. Last, but not least, some
restrictions were
accepted which were necessary due to performance
reasons.
It is definitely true that all tests done have to be written down, however, it would be beyond the scope of this chapter to present all tests done, and so only the interesting or successful ones are described.
Due to these considerations, this chapter has the following structure: First some rather general information about the tests done will be given. After this for each statistical feature of DPV, more details will be presented in the following order:
