These are still considered unit tests because they don't run inside an
OSG
i con-
tainer. You could bundle them into a fragment as you did in section 7.1 and deploy
them using Pax Exam, in which case they would be called
bundle tests
. Bundle tests
are somewhere between unit and full-blown integration tests. They test more than
a single class or feature but don't involve more than one bundle. Figure 7.7 shows
the difference.

Unit, bundle, and integration testing
After you've tested your core functionality both inside and outside the
OSG
i container,
you can move on to integration testing. Integration testing is where Pax Exam shines.
7.3.4
Integration testing
Integration tests
are where you start to piece together your application and test interac-
tions between individual components. To test combinations of components, you need
some way to compose them. For standard Java applications, it can be tricky deciding
which
JAR
files you need to load; but with
OSG
i applications, all the dependency infor-
mation is available in the metadata. Deployment becomes a simple matter of picking a
set of bundles.
