It's too bad Java/C++ were designed after unit testing became commonplace. Some of the advice here will actually improve your production code but a lot of this is just a case of the programmer having to work around the language. For example, the advice to not "instantiate objects using new in the middle of methods" wouldn't be a big deal if if your test code could easily instruct the compiler to replace the concrete object with a mock when the test is run.
