The unit tests are unbearable and the next change forces me to trash them.
Thus adding smoke tests before. The current tests aren't involved enough yet but
are a good base for further testing.

I plan to only test the most important functionalities, the ones used in the continuous build and try server.

TEST=new smoke test
