my first try was to have only one instance of MocksHelper for all tests, and to call init with the mocks list.

But the problem is that the parts before the first 'suite' in all test files are executed first, without calling the first suite in the first test file. So it's not possible to share only one instance, and therefore that's why there is first the instanciation and then the call to `init`. And also why I choose a different variable name in each test.

But I suspect it could be possible to do what you say. Just maybe not now :)
