[Abstract]:With the wide application of embedded software in aviation, aerospace and other fields, the quality of embedded software has been paid more and more attention. Once the software fails, it will directly or indirectly affect the life and property of human beings and the safety of the ecological environment. As an important means to guarantee the quality of software, software testing technology has gradually been attached importance to and applied. In this paper, based on the software test requirements of the launch and control computer IO controller developed by our hospital, a set of independent and effective third party test platform is built. The key problems in the development and testing process of IO controller software test platform of launch and control computer are studied. The main contributions of this paper are as follows: 1. The advantages and disadvantages of the current common software test process model are compared and studied. Combining with the characteristics of IO controller software in embedded launch and control system, an embedded IO controller software test process model is proposed. In order to ensure the quality of IO controller software, the test efficiency is improved. 2. According to the actual needs of the model, the static test technology is applied to the IO controller software testing, and the measurement technology in the static test is studied, and the cyclomatic complexity and the basic complexity are taken into account. The influence of fan-in / fan-out number on naval model software is discussed, and a method to reduce the static metrics of some software is proposed. 3. According to the characteristics of IO controller software, the problems existing in memory defect testing of naval equipment software are analyzed in detail, and some examples are given to illustrate the memory usage defect test of embedded software. In this paper, the code expansion rate of three logic test tools is compared and analyzed through experiments, and the preconditions of memory leak testing in several development environments are expounded, which provide the basis for the selection of test tools, and with the help of CodeTEST testing tools, The source of the memory leak of the embedded IO controller software is found, and the reasons are analyzed, and the modification method is put forward. 4. This paper analyzes the requirements and difficulties of software coverage test of embedded IO controller in launch and control system, configures Testbed/RTinsight and CodeTEST software and hardware test environment, and as far as possible does not affect the execution time of the system under test and how to obtain coverage history data effectively. The software coverage test automation of embedded IO controller is realized. This paper presents an effective solution to the test requirements of embedded software, which improves the adequacy, independence and effectiveness of embedded IO controller software testing in launch and control system. This method will also be applicable to other embedded software testing.
