this involved:
* moving that task to callback_tasks to prevent circular imports
* updating the dummy research mode callbacks (with actual SNS messages from the
ses simulator emails)
* refactoring tests
Previously research mode created a task to fake the callback from the providers. This meant there is an extra task for each notification than would be generated in a live situation.
This PR changes that, so that a research mode/test key notification calls the callback API rather than make a task to do that .
This ensures that the flow for research mode more closely mimics that of live, and removes a task from the process so we can more accurately test throughput,
This meant that the research mode task would never work.
Also the way we mark data as "temporary-failure" with firetext is with first a pending status callback then a declined callback.
This PR changes the research mode task to account for that situation.
- if a service is in research mode the don't send the notifications via the providers (MMG/SES/etc)
- instead set up a task to mimic those services callbacks - this completes the loop, and show stats, delivery receipts and so on.
- Use the "to" field to choose the response, allows users to create successful and errored notifications
temp fail sms, uses "07833333333"
perm fail sms, uses = "07822222222"
success = "07811111111" (or anything else)
success email = "delivered@simulator.notify"
perm fail = "perm-fail@simulator.notify"
temp fail = "temp-fail@simulator.notify"
