I'm trying to create tests for a submission processing step using the test framework in DS 3.0. In order to mock the environment I have to create an httpservlet request and response, but I can't find proper classes to mock them in DSpace depencencies.á

1) Is there any dependencies included by maven that helps me mocking an HttpServletRequest/Response?á

2) If not, which is the proper way to add new classes (ex MockHttpServletRequest) to the code?
