Cost of faults in testing
WebExternal failure costs – This includes product support costs incurred by delivering poor quality software. Normally, cost of detecting defects is the major part of total cost. This is the cost which is incurred even if no defects are found by the testing team. Whereas remainder cost is incurred on fixing the defects, i.e. internal failure cost. http://www.jatit.org/volumes/research-papers/Vol4No3/Regression_Testing_Average_Percentage_of_Faults_Detected_APFD_Test_Cases.pdf

WebLogical Faults 12 Stuck-at Fault model 1. Stuck at 1 fault (SA1 or s@1) 2. Stuck at 0 fault (SA0 or s@0) F1 translates to node n1 being stuck at 0, equivalent to A1 being stuck at 1. F2 result in node n1 remaining high, equivalent to A1 being stuck at 0. F3 will affect half of the n -channel pull-down stack and may result in a degradation fault. WebSpecifically, the expected cost of removing a fault during the operation phase is higher than that during the testing phase; that is, . Overall, the above cost function is the summation of the testing cost, including the failure cost during testing and actual cost of testing, and the cost of failure in the field. Proposition 1.
