Interaction Fault Detection using Combinatorial Interaction Testing and Random Testing

Software product lines are the common trend in software development which helps in reducing the development cost. Mostly the interaction faults are very difficult to identify during the process of debugging. By the use of combinatorial testing a set of features can be identified and all small combinations can be verified to a certain level only. By introducing random testing can improve the accuracy and ratio of t-wise fault detection. Through random testing can acquire a higher level of improvements over the combinatorial testing which will be under the budgetary limit of the product. Random testing can provide minimum guarantees on the probability of fault detection at any interaction level using the set of theories. For example,
