Effect of Test Coverage and Change Point on Software Reliability Growth Based on Time Variable Fault Detection Probability

In past four decades, many software reliability growth models (SRGMs) have been proposed to enhance the reliability of the software system. During the testing process potential fault sites are sensitized to detect the faults. Fault detection probability increases as learning and maturity of the testing personnel increases. Therefore, in this paper a time variant fault detection probability has been introduced and integrated into s-shaped coverage SRGM. Experimental results shows that the proposed model is better and will be helpful to improve the accuracy of the software reliability estimation.
