* Un-hardcode status message_id in test backend
For the test EmailBackend, get message ID's based on array position in
`mail.outbox`, so that tests can predict the message ID.
* Add a console backend for use in development
Adds an EmailBackend derived from both Anymail's test backend and
Django's console backend, to provide anymail statuses and signal
handling while printing messages to the console. For use during
development on localhost.
Closes#87
Within an EmailAddress (previously ParsedEmail object), properties
now match Python 3.6 email.headerregistry.Address naming:
* .email --> .addr_spec
* .name --> .display_name
* .localpart --> .username
(Completes work started in 386668908423d1d4eade90cf7a21a546a1e96514;
this updates remaining uses of old names and removes them.)
* Change Anymail's test EmailBackend to collect sent messages in
django.core.mail.outbox, same as Django's own locmem EmailBackend.
(So Django's test runner will automatically clear accumulated mail
between test cases.)
* Rename EmailMessage `test_response` attr to `anymail_test_response`
to avoid conflicts, and record merged ESP send params in
new `anymail_send_params` attr.
* Add docs
Closes#36.
* **Future breaking change:**
Rename all Anymail backends to just `EmailBackend`,
matching Django's naming convention.
(E.g., switch to "anymail.backends.mailgun.EmailBackend"
rather than "anymail.backends.mailgun.MailgunBackend".)
The old names still work, but will issue a DeprecationWarning
and will be removed in some future release.
(Apologies for this change; the old naming convention was
a holdover from Djrill, and I wanted consistency with
other Django EmailBackends before hitting 1.0.)
Fixes#49.
* Create generic TestBackend that simply collects
send parameters
* Change BackendSettingsTests to TestBackend,
and add some missing cases
* Add UnsupportedFeatureTests
* Replace repetitive per-backend SEND_DEFAULTS
test cases with single (and more comprehensive)
SendDefaultsTests
