* You will need to following Maven dependences.

Thanks for the nice example.
I have one question:
My resource class MultiPartResource does not have a no argument constructor but has one argument constructor taking Configuration class, what changes I have to make ?
I will have to mock this configuration class and pass the mock to the resource class
I get the error "Could not find a suitable constructor..." and I guess it is because of the line 'return new
ResourceConfig(MultiPartResource.class)'.

Also, if I am saving the uploaded file to disk using a private method in my resource class, how do I test this ? I tried to use the PowerMock
but it seems since I am extending the JerseyTest there is some issue.

Thanks for your help.
