Enable Mockito Tests: An Interface for Context

If Context would be an interface instead of a class, it could easily be mocked in unit tests.

My router delegates certain paths to controllers that have methods which only take a Context object. If this would be an interface, I could mock it and only unit test my controller in isolation.

All the test examples I have found in this repository use full integration test that I would like to avoid (at least for my controller unit tests).

For people arriving here wondering how to do mocking with Mockito

• If you’re using Kotlin, switch to mockk
• If you’re using Java, mock HttpServletRequest and HttpServletResponse, then pass them to ContextUtil.init(). The init function is overloaded to take all the dependencies of Context:

Context ctx = ContextUtil.init(req, res);
Context ctx = ContextUtil.init(req, res, "/:param");
Context ctx = ContextUtil.init(req, res, matchedPath, pathParams);
Context ctx = ContextUtil.init(req, res, matchedPath, pathParams, splats);
Context ctx = ContextUtil.init(req, res, matchedPath, pathParams, splats, handlerType);

Yep, thanks for your work @tipsy!
