Reduction in Software Engineering Using Pair Wise Approach
Testing is a very significant task to evolve error free programs. Since the assets and time is restricted to produce software, therefore, it is not likely of performing exhaustive tests (i.e. to check all likely combinations of input data.) So answer to this problem is pair-wise approach. Pair-wise or two-way interaction testing needs for a granted numbers of input parameters to the scheme, each likely combination of values for any two of parameters. The main concepts of the method is that the authors firstly investigates the dependant relations amidst input parameters, then use the relations to decrease ineffective pair-wise combinations of input parameters, and finally develop the pair-wise combinatorial coverage check suite.
