Hi Pavel,
Setting up and using the Jersey Test Framework seems more like an integration test to me rather than a unit test.
Same thing goes for using it to bring up a resource and then using the Jersey client to make REST calls.
They will require having databases set up with test data and so on just to make one unit test pass....
That seems rather excessive for a unit test (but totally okay for an integration test).
The Client class is not final and has a default constructor, so it seems cglib/EasyMock would work here.
I'll try it out and let you know how that goes.
Ronak

Subject: [Jersey] Re: Unit Testing code that uses the Jersey Client API
Hi,
I wouldn't try to mock jersey client, it looks like hard thing to do
- it is too complex for this I think.
You have several options how to approach this:
1) using jersey test framework
you should be able to create (or maybe reuse if you already have
them) resources which could serve similarly as mocking. You might be
able to use in memory container, so it would be fast. But this
depends on the code you want to test - it might not be possible (for
example, you'll need to have the possibility to use client provided
by framework). And additionally, Jersey server (runtime
dependencies) and related dependencies are needed for this to work.
2) hacking jersey client
it is possible to subclass or modify jersey client to *not*
actually call any rest service, all you need to do is implement your
own TerminatingClientHandler, see [1] for example.
both proposed solutions require some additional code, but I like
first option more..
I would like to know what path are you going to choose, so please
keep us posted :)
Regards,
Pavel
