Yes and no. The base image we build today only contains

components from one module, Base Runtime, however, that
will definitely change for F27 (and possibly even for F26).
We expect to use components from composes made of multiple
different modules.

Therefore I'm more interested in "integration level" type of
tests rather than testing modules in isolation.

OK, in that case we could help you create a "generic" task for Taskotron that gets triggered every time there's a new Boltron image built (the build system would need to send a fedmsg from which we can detect this) and the Taskotron task would then download the image and run your test suite, then report results to ResultsDB. There are no existing similar tasks yet (testing docker images), at least in Taskotron.
