Abstract

The invention provides a safety-level software testing method for a nuclear power plant, which comprises the following steps: according to the software classification of a nuclear power plant to be tested, selecting a test task corresponding to the safety classification of the tested object from a test task database; According to the tasks selected by the test task library, the software requirements are decomposed to fit the test tasks, and the software requirements are located. the test items corresponding to each test task are given through the expert support library. According to the software requirements and test items, the software test strategy is determined, the test description is generated, the test work is executed, the test result is recorded and the execution result is analyzed. The invention realizes the test of the safety-level software of the nuclear power plant with fewer test cases, improves the adequacy and completeness of the test, and improves the test efficiency. At the same time, the defect analysis module can quickly locate the defect causes and update the expert support module to enhance the accuracy and applicability of the platform.

Description

technical field [0001] The invention relates to the field of software testing, in particular to the field of nuclear power plant software testing, in particular to a nuclear power plant safety level software testing method and device. Background technique [0002] Software testing is an activity aimed at evaluating the properties of a program or system, and testing is a measure of software quality. With the popularization and application of digital technology in nuclear power plants, according to the requirements of relevant standards and regulations, the proof of correctness and safety of computer-based systems important to safety requires various verification and confirmation activities. Software testing is important for the verification and confirmation of safety-level software in nuclear power plants is an essential activity. [0003] Since the requirements for safety-level software of nuclear power plants include functional requirements and operation requirements under...
