Adaptive random testing (ART) is a testing method aimed to improve the performance of random testing. The initial studies of ART merely focussed on programs with numeric input type. However, real life software involves more complex types of inputs. This thesis examines the application of ART on programs with complex input types. Firstly, the application of a distance-based ART technique, namely FSCS-ART, on real programs with complex input types is conducted. This is an extension of two previous studies which deve…
