The Layout plugin and the KWTextDocumentLayout are indeed two separate units, and \
should be tested separately. This is possibly by defining the interactions between \
the two and figuring out what you expect to happen which doesn't happen right now. \
After defining the interaction and deciding which of the two sides is buggy (either \
the provider of the API or the user of the API) you write a unit test based on that \
conclusion; you either write a test that tests the provider of the API or you write a \
test testing the consumer of the API.
In your explanation it seems you don't have a clear picture yet of the contract of \
the APIs since you say you need both at the same time. That may be a good place to \
start.
Also, I think there are various partners listed on the Qt website that provide \
training for writing unit tests, if you and your company lacks that knowledge please \
consider contacting them. I'm have to be honest in that I don't really have the time \
to explain those concepts in my spare time, for free, to a for-pay subcontractor.
