Hi Gili,

I am not convinced that mocking-up without using HTTP is the correct
approach, you application is designed to be consumed by HTTP clients,
IMHO should be tested using a similar mechanism, with code coverage
analysis telling you what bits of the server side are not currently
tested. But others views differ.

The Jersey tests do the following:

- use embedded HTTP servers like Grizzly, GF and Jetty; or

- use a special in memory connection.

and make use of Jersey client API. The tests are not really unit tests
more functional tests that use the unit test framework because it is
so convenient. We are planning to create a separate testing framework
to make it easier for developers to create such tests.

Paul.
