I don't remember all the functionality you showed yesterday, but I think there were other things worth testing:
1. each medication had two buttons for two final states, besides submit is the other path tested?
2. the medications were being grouped under the history, should that be tested?
3. test you can delete individual medication rows
4. are there any rules about dates, like starting after ending, that could be tested?
5. If there's persistence while filling out a medication, is that tested?
