In the past, various Software Reliability Growth Models (SRGMs) have been proposed using dif-ferent parameters to improve software worthiness. testingcoverage is one such parameter that has been studied in numerous models of software in the past and it has proved its influence on the reliability models. To sustain themselves in the market, software firms keep upgrading their soft-ware with new features or enhancements by rectifying previously reported faults. Also, there is an impact of the random effect on testingcoverage during both the testing and operational phase. In this paper, we have proposed a Software reliability growth model based on testingcoverage with random effect along with imperfect debugging. Later, the multi-release problem is presented for the proposed model. The proposed model is validated on the dataset from Tandem Computers. The results for each release of the models have been discussed based on the different performance criteria. The numerical results illustrate that models fit the failure data *** dot The random effect in the testingcoverage rate is handled using Stochastic Differential Equa-tions (sde).center dot Three testingcoverage functions used are Exponential, Weibull, and *** dot Four Releases of the software model has been presented.
