## This test:
##   - starts up a client and a provider
##   - checks for the provided values on the client stdout
##   - starts a commander with a different value for that property
##   - checks the output for the changed value
##   - changes the value inside the commander to unknown, check it
##   - changes the value inside the commander back to some meaningful value, check it
##   - kills the commander
##   - checks that value goes back to normal
