The dymo-cups-drivers-testing package
does basic testing of dymo-cups-drivers
during build-time of dymo-cups-drivers-testing.

The tests are re-done automatically whenever
a build requirement of dymo-cups-drivers-testing changes
via the automated package rebuilds in OBS.
Explicit build requirements of dymo-cups-drivers-testing
are dymo-cups-drivers plus cups and cups-filters
(i.e. what constitutes the base printing system).

It tests dymo-cups-drivers for CUPS
by running the drivers via the cupsfilter program.
