As we know every software development process is pretty large and consists of different modules. This raises the idea of prioritizing different software modules so that important modules can be tested by preference. In the software testing process, it is not possible to test each and every module regressively, which is due to time and cost constraints. To deal with these constraints, this paper proposes an approach that is based on the fuzzy multi-criteria approach for prioritizing several software modules and calculates optimal time and cost for software testing by using fuzzy logic and the fault tolerance approach.

In this paper, we estimated the exact software defect density to build up a suitable model that is closely related to the size of module in the probability model proposed by MD (Malaiya and Denton). To put it concretely, we predict that the software defect density using some practical data sets that are the outcomes from the system test performed our three projects for the types of distribution (exponential and geometric), per a unit of module, and the size of source line that have been recommended by KLOC(kilo-line-of-code). Then, we make comparison between our proposed defect density model and those examined real data.
