I work on expanding Test::MockDBI to address some of its limitations (e.g. support for fetchrow_hashref and control of errstr, see also a cpanratings review). It uses a test setup where test programs are generated on the fly. The motivation for doing so is noted in the HISTORY:
- The separate test programs are autogenerated so they use the correct #! startup line.
It works like this: It strikes me as unnecessarily complex. If I were to expand the module, do you think I should continue using the same approach?

No matter how great and destructive your problems may seem now, remember, you've probably only seen the tip of them. [1]
