Constraint Handling In Combinatorial Test Generation Using Forbidden Tuples

Raghu N. Kacker, David R. Kuhn, Yu Lei
Constraint handling is a challenging problem in combinatorial test generation. In general, there are two ways to handle constraints, i.e., constraint solving and forbidden tuples. In our early work we proposed a constraint handling approach based on

Improving IPOG’s Vertical Growth Based on a Graph Coloring Scheme

Raghu N. Kacker, David R. Kuhn, Yu Lei
In this paper, we show that the vertical growth phase of IPOG is optimal for t-way test generation when t = 2, but it is no longer optimal when t is greater than 2. We present an improvement that reduces the number of tests generated during vertical growth
