I am also in the process of making GWT-RPC method implementation independent of GWT-RPC/Servlet for easier testing. I don't really bother about introducing new short lived objects created for each request. Short living objects are not a real problem in todays JVMs and you can probably save a lot more resources by optimizing heavy weight algorithms, etc. But as always: Only start optimizing if you have to because some service is too slow or consumes too much resources. As long as everything works fine just write clear, easy to understand code.
So in case of GWT-RPC + command pattern you maybe end up with something like: public Result execute(Command cmd) { HttpSession session = getThreadLocalRequest().getSession(); //HttpSession needs to be mocked or stubbed Cache cache = new SessionBackedCache(session); //following code does not know anything about servlets and GWT-RPC CommandDispatcher dispatcher = new DefaultCommandDispatcher(); CommandExecutor executor = new DefaultCommandExecutor(cache, dispatcher); Result result = executor.execute(cmd); return result; } With this code you can unit test SessionBackedCache, DefaultCommandDispatcher, DefaultCommandExecutor and then I would think twice if I would write a test case for the GWT-RPC method itself as its implementation is super simple. When using an injection library like google-guice this code would probably be even shorter. If I could avoid it, I would never delegate to a private method, like in your example code, and then make this private method accessible again using reflection during tests. IMHO tests should cover public methods and not private ones. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
