Various Techniques to Detect and Predict Faults in Software System: Survey

Software reliability is frequently estimated as per occurrence of failure and its recurrence, or as far as framework accessibility. Software is often categorized as system software (such as operating system, or program that assists application software etc.), application software (such as spread sheets, CAD / CAM, graphic software, etc.), shareware (generally planned for sale after trial duration), literate (available with few conditioned abilities), freeware, public domain or open source Almost, all frameworks have tendency to have faults however not each of them result in failure. Software fault prediction (SFP) approaches can be used to predict the faults. The objective of the fault prediction is to reduce errors and its influence before failure happens. In particular cases, where failure has just happened, fast recovery is major task. This review provide overview about the software, faults, fault prediction, detection and prevention strategies rehearsed and examined. Benefits and drawbacks of those mechanisms are also discussed. Several previous work is reviewed and compared with respect to used techniques and performances parameters
