[geos-devel] CascadedPolygonUnion XML testing

[G. Allegri]

Here is a test xml:
http://www.giovanniallegri.it/share/TestUnionMultiPolygon.xml
It's big, but I will reduce it nex time :)

Notes:

1 - this multipolygon comes from an st_collect on 95 rows in a postgis
table. The test on it fails with Topology Expection found non-noded
intersection, because the MP is invalid. I've tested it on jts from
trunk.
2 - I've run a cascadedunion.union operation on a List of the same
geometries (picked with Geotools directly from the DB). It works fine.
In this test I've used jts 1.10 shipped with Geotools. I will try it
agains the trunk version as soon as possible.
