Proces testowania oprogramowania zintegrowanego systemu monitorowania i sterowania

W artykule została przedstawiona metodyka testowania oprogramowania złożonych zintegrowanych systemów monitorowania i sterowania. Przedstawiono przykład wykorzystania proponowanej metodyki podczas procesu testowania oprogramowania zintegrowanego systemu monitorowania i sterowania państwowego wzorca jednostek miar czasu i częstotliwości (PWJMCiC).

In the paper, software testing process of an integrated system for monitoring and control of national unit standard time and frequency systems (PWJMCiC) based on the assumed methodology is presented. There is also described the methodology procedure developed for implementation of complex control-measuring systems. In the introduction there are shown examples proving the fact that the waterfall model (Fig.1), used most frequently for design of simple, uncomplicated measurement systems, has drawbacks. They make its application to the complex integrated systems for monitoring and control impossible. Next, there is presented a methodology WU-CMD (Waterfall User-Centered Design Model) developed by the author. It combines elements of methodology for User-Centered Design [3] and elements of the waterfall model [4]. The proposed methodology assumes that the assumptions for a measurement system are formed on the basis of analysis of future user's needs, and the future user of the measurement system participates at all stages of its design, through reporting comments and accepting changes. Each stage of the design is time-bound and documented in detail, for each of the stages there are specified requirements that must be met to make it possible to finish the stage. It is also assumed that at each stage there are carried out tests of compliance, accuracy and consistency of implementation of individual elements (as well as the whole) of the designed measurement system.
