About using fragments, the only drawback I'm aware of is that one
cannot add a dependency to a fragment from their plugin. So it's not
possible for other tests to reuse some logic that is inside a
fragment. In the spirit of "treating tests as 1st class citizen", I
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.
About maven-surefire (plain Java) vs tycho-surefire (OSGi/Eclipse), so
far, we do not test the code of JBoss Tools outside of the "Eclipse"
context. We can debate about the meaning of "unit tests", but what you
see can be seen as "unit tests running in integration context". Our
experience with some other parts of JBoss Tools have been that the
difference of behavior between inside or outside of Eclipse can be
important. So our policy has been so far to test everything with
tycho-surefire-plugin to make sure what we're testing isn't too far
from what will actually happen in production.
important difference of behavior which can be important is a good
argument. On the other hand, some integration tests should be able to
The QE people could tell you their opinion on what's more
between fast tests, and longer tests that are closer from production.
I guess it all depends, as always: we could imagine the unit test
running in plain Java to verify only their logic, but it shouldn't
become a replacement to some integration test to verify that the logic
also works in the right context.
Not planned to have them as a replacement. I
already created the
structure to write also higher integration tests.
I would say that as long as Eclipse is the *only* deployment context
for a piece of code, then starting unit tests inside Eclipse is fine.
Also, for fast unit tests, then they are neglictable compared to
starting up the OSGi Platform. So if we want to start an OSGi platform
anyway for integration tests, it seems simpler to run those tests
inside that Platform.
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.
