1. getMock()
2. setExpectedException()
3. checkForUnintentionallyCoveredCode renamed to beStrictAboutCoversAnnotation
4. beStrictAboutTestSize renamed to enforceTimeLimit
5. UnitTestCase class is now fully removed.
These unit tests were modifying the PAGE and other globals in the middle of
tests and were failing as a result.
Broke the tests up into separate tests where the functionality is now
tested individually.
This unit test does not verify contents, details, but only
that the returned users for every group mode, for every
filtering (active, groupid and withcapability) together
with permissions are correct.
1. core_enrol_get_course_enrolment_methods() which returns all enrolment method instances
which implement get_enrol_info()
2. enrol_self_get_instance_info() will return information about self enrolment instance.
core_role_external::assign_roles() now support alternative paramaters instead of contextid. Test working of those. Also test the parameters validation a bit, since these are no longer automatically tested being optional now
