Related changes:
* remove Travis-CI config; stop running tests on Travis
* rename live integration test environment variables
to all start with `ANYMAIL_TEST_` (simplifies tox config)
Switch from the (now unmaintained) python-sparkpost
client library to a requests-based backend that calls
SparkPost's Transmissions API directly.
Also adds support for text/x-amp-html alternative parts
(which are supported by the SparkPost API, but weren't
by the client library).
Closes#203
Minimum supported versions are now Django 2.0, Python 3.5.
This touches a lot of code, to:
* Remove obsolete portability code and workarounds
(six, backports of email parsers, test utils, etc.)
* Use Python 3 syntax (class defs, raise ... from, etc.)
* Correct inheritance for mixin classes
* Fix outdated docs content and links
* Suppress Python 3 "unclosed SSLSocket" ResourceWarnings
that are beyond our control (in integration tests due to boto3,
python-sparkpost)
Tox:
* Add Tox factor for extras (all, none, individual ESP).
For now, only break out ESPs that have specific extra
dependencies (amazon_ses, sparkpost).
* Install most package dependencies (including extras)
through the package itself.
* Use new runtests.py environment vars to limit test tags
when Tox isn't installing all extras.
Travis:
* Rework matrix to request specific TOXENVs directly;
drop tox-travis.
Test runner (runtests.py):
* Centralize RUN_LIVE_TESTS logic in runtests.py
* Add ANYMAIL_ONLY_TEST and ANYMAIL_SKIP_TESTS env vars
(comma-separated lists of tags)
Test implementations:
* Tag all ESP-specific tests with ESP
* Tag live tests with "live"
* Don't import ESP-specific packages at test module level.
(Test discovery imports test modules before tag-based filtering.)
Closes#104
* Set up tox for testing supported Django/Python combinations
* Also include tox env for checking and building docs
* Use tox-travis for Travis CI integration
* Add tests against Django master
* Document building docs and running tests with tox
Install default warnings filter in test runs, to avoid
python's default suppression of DeprecationWarning
and other "intended for developer" warnings.
(Avoids need to provide -Wd or -Wall arg to runtests.)
(Improves testing accuracy around API response encoding.)
* Add `six` as test dependency (six.BytesIO, six.b)
* Change MockResponse content to bytes (because HTTP responses
are bytes, not strings)
