The Software Error Estimation Program (SWEEP), developed by the Software Productivity Consortium, is a predictive tool for calculating the error rate, including estimating the percentage of hidden errors. A hidden error is any error that remains in the program product, i.e. such an error that exists, but not yet detected. The value of the SWEEP model is that it simplifies the management and forecasting of errors in software intensive systems. This model supports the definition of error detection targets during software development and helps to track progress towards achieving these goals. By predicting the number of errors remaining in the software system, SWEEP monitors and helps to control the quality of software products. Below is a list of assumptions underlying the model:
Are you looking for good QA specialists that can solve even complicated development tasks? These people are Ukrainian testing service providers who do the quality assurance work for overseas customers, saving them the trouble of hiring expensive experts.
Familiarization with the three modes of using the SWEEP program
SWEEP offers software testers a clear graphical representation of the detected errors and the forecast of the remaining errors.
