In this paper, the methods of the software engineerization development and a scheme of the qualitative and quantitative assessment of software reliability and safety are introduced. The significance of the safety software engineerization development and the management in the micro-computer control system, three kinds of standards which should be obeyed during software development in our country, and four safety grades which should be classified according to the failure consequence in our national railway signalling safety software are clarified. And a basic method of making use of software test and assessment is discussed. On the other hand, a test and assessment platform based on 'black box' or 'grey box' is put forward.The major parts of the platform include the comparison surrounding, the operation set, the running set, the physical simulation system, the qualitative and quantitative assessment module etc. Before the test, those normal and abnormal operation set and running set shoud not be only defined, but also classified into subsets. By running these subsets on the platform, the qualitative assessment and quantitative measurement of reliability and safety of the tested software system can be obtained.
