Correct. That's why we introduced the testing framework and the
functional testing part. The old components successfully ignored
principles of software development and had approx. 8123 possibilities to
be called in a different context and resulting in undocumented but
existing behaviour.

Or the other way round: Fixing bugs in e.g. DataHandler had good chances
to introduce new bugs by changing some behaviour...

All the best
