In the life cycle of software product, testing process is one of the important methods to ensure the software reliability. According to the research in the software engineering, the earlier the testing process begins, the lower the cost is for correcting the errors. Due to the specialty of embedded software, the functional test can not be carried out until the hardware has been developed. So, how to begin test process as early as possible has been one of the research fields in embedded software testing technology. The research in western countries began earlier than in our country and rich fruits have been achieved. So a big gap exists between western country and our country, which is one of the obstacles that hinder the embedded software researching and developing in our country.In order to enhance the ability of developing embedded software, a project was built in 2001, which focus on the control techniques of embedded software quality. In this project, a sub-project (project number: 418010704-3), research on the simulating test bed for embedded software, was form to solve the difficulty of testing embedded software. This paper was written based on this project. The achievements include:1 , emphasized the importance of test process for ensuring the quality of software and concluded the phases of test process after reviewed the history of software testing and stated the inner and outer meaning of software testing.2, concluded the model for enhancing the ability of developing embedded software, state the importance of the simulating test bed after study the reason which cause the difficulty for testing embedded software and compared three models.3, Design a part of architecture of the simulating test bed, suggest the five modules of the test bed and their relations, a software requirement decomposed method(SSR) was introduced and finally discussed the relations between SSR and STCL .4, Design the inner structure of the STCL module, devised some techniques to solve the difficulties, and put them into executable modules.This paper focused on the testing technology for embedded software and did deep research in this field and a module (STCL) of the simulating test bed. And a firm foundation was formed for later research.
