Method test_constructor

python/ee/tests/geometry_test.py:687–730

Check the behavior of the Geometry constructor. There are 5 options: 1) A geoJSON object. 2) A not-computed geometry. 3) A not-computed geometry with overrides. 4) A computed geometry with no overrides. 5) something to cast to geometry.
