Devise hasn't been tested with Mongoid since Rails version 5, only 4.x was still running those tests.
This enables the tests again on all currently supported Rails versions, with their respective mongoid supported versions. There were a couple of minor tweaks to make it happen, namely:
* The way we were dropping the session before doesn't work in later versions so I changed back to calling `purge!` which appears to work fine. We used to call `Mongoid.purge!` but that changed in #4686.
* Some of the configs in the Rails test app were setting Active Record values when outside of the AR ORM tests, updated those to make sure they are not set when running mongoid ORM tests.
* The validations added to the shared admin code in tests were only checking for Rails version 5.1, but we need to use the same check for AR 5.1 that is used in code, otherwise it will try to use methods not available in mongoid there.
This has no actual changes to Devise itself, just fixes the failing
tests when running against Mongoid 3 instead of Mongoid 2.
Mocha has been locked at 0.10.0 since 0.12.0 raises an error when trying
to set an expectation on a frozen object.
Tests were updated to work with both AR and Mongoid, some cases the XML
serialization was slightly different but both were outputting correct
and valid XML, and the id/_id field mismatch is now handled.
An active field was missing from the test models for Mongoid, and the
invalid :null => true options in field were removed.
- attr_accessible not set for test user model, making Serializable tests
inaccurate
- Mongoid does not `include_root_in_json` by default, so enable this for
consistency with AR tests
- Mark tests pending for Mongoid < 2.1 that fail there due to known bugs
- Add `:mongoid` key for i18n model labels
- Remove outdated shim of `update_attribute` that caused mass assignment
security to be applied (ugh, that took awhile to find)
