Integration testing through some shell unit-testing framework

[noway]

Maybe make integration tests directly with shell testing frameworks, instead of python? bin_tests.py currently implemented with python, and it's not very handy to edit and maintain. Some shell testing framework would be much better suited for this task. https://code.google.com/p/shunit2/ and https://bmizerany.github.io/roundup/ are nice candidates.

In addition to that some real-life testing with "journalctl -o json -f" would be much appreciated.
