believe it's generally better to allow composition of test bundles and
to make them regular bundles.
If reusable, the logic can be moved to a dedicated utility test plugin.
Yes, but it
requires an effort in moving the code to the right plugin or
turning fragment into a bundle everytime one identifies something to
reuse; whereas using bundles only doesn't require any effort from the
"producer" side.
On the other hand, some integration tests should be able to detect
that.
That would require writing some additional integration tests, whereas
the current approach to run "unit" tests inside a workbench provide that
verification without additional thing to write.

Not planned to have them as a replacement. I already created the
structure to write also higher integration tests.
If, during automated tests/build,
you run both unit tests and then start
a workbench to run integration tests, then you pay the price of the
workbench startup anyway. So why not running those unit tests in the
workbench?
When running locally, I may want to run only unit tests first.
Without launching the OSGi platform it will be faster. It will also
allow to use some tools such as Infinitest to have continuous feedback
while developing.
I don't know much of Infinitest, but I believe it doesn't
rely on how
Maven runs tests. Eclipse already provide the ability to run a test
class in a bundle in plain Java without starting the workbench; it's
"Run As > JUnit Test" instead of "Run As > JUnit Plugin Test". I
guess
Infinitest can rely on that, can't it?
Just to be clear, I'm not saying it's wrong to change that; I'm more
wonderint how much profitable is it, what changing test structure would
provide better than the current one does. The Infinitest story seems the
only one "worth it" IMO, and it doesn't seem to be correlated to
tycho-surefire vs maven-surefire.
