Figure out if core processors actually work.....
The processors we currently ship with core are
|Eway||works/tested/ converted to an extension|
|FirstData||broken? (Reported as working by Brian Civi Version not mentioned)|
|PayflowPro||broken? (Reported as working as of 5.19 by Nicholas) (As of 5.38 Migrated to a core extension with unit tests)|
|PaymentExpress||definitely broken / removed|
|Realex||likely works, have seen gitlabs|
I think we should try to find out about the ones that might be broken with a view to either
- bring them under CI & move to an extension (per Eway) OR
- remove them from core
Other than pinging people like @lcdweb to see if they use any my other idea is to add a check or preUpgrade message to try to get people to let us know.
