Comment (by Algunenano):

 I've added the tests for ST_Covers and ST_CoveredBy.

 I don't see an easy way to test the change in `st_containsproperly` since
 the bug (it was using `&&` instead of `~`) doesn't have an impact in the
 results; all cases where `a ~ b`  are included in `a && b` (but not the
 other way around) except when b is EMPTY , but then `containsproperly`
 discards empty geometries. I'm not aware of any way to check whether the
 result comes from the index operator or the C function itself.
