This research shows a case study of the Black-Box testing for Temperature Controller (TC) which is one of the typical embedded systems. A test automation tool, TEST, was developed and some kinds of TCs were tested using the tool. We presented statistical analysis for the test results of the automated testing and defined the properties of the software bugs for the embedded system. The main result of the study were the following: (a) test case prioritization technique was needed because the review phase, in the test process, takes long time; (b) there are three types of software defects for the embedded software; (c) the complexity of the system configuration have an effect on the software de-fect; (d) the software defect was distributed in vulnerable points of the software; and (e) testing activi-ties reduce the number of the software defects. The result can be useful in the asymptotic study of test case prioritization.
