“…Example strategies that adopt this approach includes An Automatic Efficient Test Generator (AETG) (Cohen, Dalal et al 1996;Cohen, Dalal et al 1997), its variant (mAETG) , PICT [8,36], IPOG (Lei, Kacker et al 2007), Jenny (Pallas 2003), TVG (Yu-Wen and Aldiwan 2000; Arshem 2010), IRPS , GTWay (Klaib 2009;Zamli, Klaib et al 2011), MIPOG Younis and Zamli 2010), TConfig (Williams 2000;Williams 2010), TCG (Tung and Aldiwan 2000)). Another variant of the computational based approach is based on meta-heuristics algorithm including that of GA (Shiba, Tsuchiya et al 2004), HSS (Alsewari and Zamli 2012), PSTG Ahmed and Zamli 2011;Ahmed, Zamli et al 2012), SA (Stardom 2001;Cohen, Colbourn et al 2008), and ACA (Shiba, Tsuchiya et al 2004)). Although useful to help test engineers sample combinatorial test suite, the support for constraints within the aforementioned strategies have not been sufficiently considered.…”
