Inspired by your question, I created an example extension and wrote a 
blog post about that topic:

This shouldn't be necessary.

The class loading issue should be tackled when following my tutorial.

This looks like incomplete mocking.
Where do you configure that? When executing unit tests only a very 
limited TYPO3 bootstrap is executed, basically only that classes are 
loaded. This means your tests must not call other TYPO3 API and of 
course do not make database connections.

Should also work when you follow my tutorial.

If you need a DB connection in your tests, or a more complete TYPO3 
setup, functional tests are your indeed friend.
