There are 3 main changes in this commit: * CohortFactory now sets up memberships properly, so consuming tests do not need to explicitly touch CourseUserGroup.users to add() users. * test_get_cohort_sql_queries has been updated to 3 and 9 queries when using and not using the cache, respectively. This is needed due to each operation needing an extra queery to get the CourseUserGroup from the CohortMembership. * Adding remove_user_from_cohort(), the counterpart to add_user_to_cohort(). This is also to keep tests from touching the users field directly, and keep CohortMembership data in sync.
Open edX -------- This is the root package for Open edX. The intent is that all importable code from Open edX will eventually live here, including the code in the lms, cms, and common directories. If you're adding a new Django app, place it in core/djangoapps. If you're adding code that defines no Django models or views of its own but is widely useful, put it in core/lib. Note: All new code should be created in this package, and the legacy code will be moved here gradually. For now the code is not structured like this, and hence legacy code will continue to live in a number of different packages.
