• order-deletion - order-proposal-lifecycle - Ensure that Order Proposals only appear in the feed when they are updated

Feature

order-deletion

Use Case

The purpose of these tests is to assure the stability of other tests that use the Order or Order Proposal feeds

• order-lifecycle test
  • Order should only be added to Orders feed after it updated following B
  • Make a booking using C1, C2, and B, then assert that the Order has not yet appeared in the Orders feed (does this need a timeout of some sort? is there a better way of doing this?)
• order-proposal-lifecycle test
  • Order should only be added to Orders feed after it updated following P
  • Create an Order Proposal using C1, C2, and P, then assert that the Order does not appear in the Orders feed (does this need a timeout of some sort? is there a better way of doing this?)

Why this hasn't been covered by existing tests

Existing tests only check the Order/Proposal feeds after an update is expected.

Additional context

This was originally grafted onto this issue: #441. There is some discussion about implementation approach in there
