Metamorphic Testing of a Superficial Area Calculation Program

In this paper, we try to apply metamorphic testing in a superficial area calculation program, which is common for most of the GIS systems. We construct metamorphic relation (MR) with different properties and characters of the program and its algorithm. These MRs construction methods are also useful for other programs testing of GIS system. At last, we compare effectiveness of different MRs based on the failure detection ability. This exploration would provide a feasible method for GIS program testing.
