We were previously expecting the letter response files to be in the
format of 'NOTIFY.<datetime>.RSP.TXT' but the response files we receive
use '-' in the filenames instead of '.' which was causing an error when
we tried to get the date from the filename.
- as the response is fake, the notifications billable_unit is left at 0, the fake dvla response should also be 0. Otherwise there will be confusing logs reporting mismatched page count and billable units which are just research ones.
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
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"
