Cost estimation of testing is therefore very important for feasibility study and scheduling of system development. This research intends to find a convenient and improved model for estimating the cost of software testing. The research first collects 17 real projects of software testing in the last five years. Based on past theories, possible variables affecting the cost of testing are decided. Then the technique of factor analysis is used to filter out important variables that are independent of each other. Finally, nine factors stand up after regression and collinearity analysis. These nine factors are: complexity, reliability, interface, defect rate, modern programming skill, tool, schedule demand, test cycle, and test experience. This result shows that domestic testing is very different from that of the United States. Comparing our model with COCOMO model, our model is noticeably simpler and more accurate.
