At first, to validate the software test, some concepts are defined quantitatively, for example the robustness of software, the reliability of software, and the security of software. Then the development tools and simulators of discrete event drive operating system are compared, in order to present robustness, reliability and security of software test approach based on input-output function. Some simple preliminary test results are given to show that different development software can obtain almost same measurement and communication results although the software of special application may be different than normal application.
