# Test plan:
#
#   rtree-1.*: Creating/destroying r-tree tables.
#   rtree-2.*: Test the implicit constraints - unique rowid and
#              (coord[N]<=coord[N+1]) for even values of N. Also
#              automatic assigning of rowid values.
#   rtree-3.*: Linear scans of r-tree data.
#   rtree-4.*: Test INSERT
#   rtree-5.*: Test DELETE
#   rtree-6.*: Test UPDATE
#   rtree-7.*: Test renaming an r-tree table.
#   rtree-8.*: Test constrained scans of r-tree data.
#
#   rtree-12.*: Test that on-conflict clauses are supported.
#   rtree-13.*: Test that bug [d2889096e7bdeac6d] has been fixed.
#   rtree-14.*: Test if a non-integer is inserted into the PK column of an
#               r-tree table, it is converted to an integer before being
#               inserted. Also that if a non-numeric is inserted into one
#               of the min/max dimension columns, it is converted to the
#               required type before being inserted.
#   rtree-15.*: Check that DROP TABLE works within a transaction that
#               writes to an r-tree table.
