The Research and Application of Test Method for 1E I&C System Platform’s Change

During the development and application of 1E I&C system platform, it’s inevitable to have change. There are two requirements to the change verification: one is to assure the changed platform has high quality, new defects can’t be produced, therefore the safety accidents can be avoided, and the other is to make the change to accomplish quickly. At present, there isn’t a systematic regression test method to these 1E I&C system platform’s changes in factory. This paper introduces a regression test method based on the analysis of changes: sort the changes, and provide impact analysis principles to every change category, and eventually establish a systematic test process and method. This method can not only assure the process’s integrity and platform’s high quality but also reduce the test cost. This method has been successfully applied to 1E I&C system platform FirmSys change testing process and obtain good effects.
