Intended final settings structure
See https://github.com/openedx/edx-platform/blob/master/docs/decisions/0022-settings-simplification.rst#target-settings-structure-for-edx-platform
Open questions
- When exactly do we "rebase" Tutor's settings onto (lms,cms)/envs/(common,development)? Most likely, we should do it all at once when those four files are ready, as Tutor's settings are all coupled together into a Jinja hierarchy.
- Should the settings object should have same type signature between LMS and CMS?
Some general Testing Notes (Update as we improve this)
