Comment # 8 on bug 922023 from Stefan Hundhammer

IMHO the most robust approach would be to create a minimalistic UI component
class derived from YUIComponent and use that one in the RSpec case.

It doesn't need to do much, but it has to comply with the requirements of those
UI components, such as providing a UI plugin (a shared lib) that can be loaded
with dlopen().

Maybe a few shortcuts are possible to avoid writing a full-blown UI. We'll need
to research that.

Back then, this YUIComponent magic was introduced to integrate with the
Y2ComponentBroker that managed the YaST2 components in the YCP world. We might
not need all of that, but - unless we want to rewrite major parts completely -
we'll have to fulfil at least the minimal parts of those call protocols.
