Hi Paolo,
yes you're right! I just noticed that I got confused by the ubuntu_lttng_smoke_test which only has just one single test in the control file.

The initalize() method is indeed being called EVERY TIME when the test is started. So the actual workflow is like this:
1. initialize()
2. setup()
3. run_once() with stressors
4. initialize()
5. run_once()

From the document [1]:
initialize() - This is run before everything, every time the test is run.
