Test BSM Message Count Progression

Integration Test for BSM Message Count Progression

Inputs

A series of BSM Messages:

1. A baseline BSM.
2. 1 second later, a changed BSM with an incremented message count.
3. 200 ms later, a changed BSM with the same message count. This generates an event, because the change should have led to a message count increment.
4. 200 ms later, a changed BSM with a message count increased by 10. This generates an event, because the message count should have only increased by 1.
5. 200 ms later, a changed BSM with an incremented message count.
6. 200 ms later, a changed BSM with an incremented message count that wraps around from 127 to 0. This does not generate an event.
7. 3 seconds later, a changed BSM with a message count increased by 10. This does not generate an event, because the different message appears outside the maximum time window of 500 ms.
8. 200 ms later, a changed BSM with an incremented message count.
