Description

unit test SplitSplice_test to verify proper working of the »SplitSplice« algorithm.

This is a generic setup to modify a segmentation (partitioning) of an ordered axis; the axis is represented as a collection of segments, which are assumed to be ordered and seamless, with the start point inclusive and the end point exclusive (thus the start of the next segment is identical with the end point of the current segment).

This test uses the natural number axis between -100 ... +100 and establishes a binding for the generic algorithm with suitably rigged test data, to verify the algorithm properly inserts a new segment under all conceivable circumstances, since there are many possibilities of arrangement for two ordered segments of arbitrary length.
