Abstract: Rapid growth of software usage enforces us to assess the Software reliability, a critical task in the development of a software system. In this Paper a well known test procedure of statistical science called as Sequential Probability Ratio Test(SPRT) is adopted for Logarithmic Poisson Execution Time Model (LPETM) in assessing the reliability of a developed software. It requires considerably less number of observations when compared with the other existing testing procedures. The model is inspected by using live Data Sets.
Keywords: Software Reliability, SPRT, Maximum Likelihood Estimation, Software Testing, Mean Value Function.

Scope of the Article: Systems and Software Engineering
