[0023] The DCS controller is a key device in the DCS system responsible for data processing and control command generation. It receives real-time data from field sensors and other equipment, performs calculations and judgments based on preset control strategies, and then generates corresponding control instructions, which are sent to the actuators through the communication network to achieve automated control of industrial processes.

[0024] Trusted DCS controllers not only have the control, monitoring and data processing functions of traditional DCS controllers, but also place special emphasis on the security and trustworthiness of the system. Through a series of security mechanisms and strategies, it ensures that the control system can operate stably in the face of various potential threats and prevents security issues such as data leakage, tampering and illegal access.

[0025] Squish coco is a code coverage analysis tool that provides a complete code coverage solution for multiple programming languages ​​and platforms, and can provide detailed code coverage reports and advanced analysis capabilities.

[0026] Code change tools are an integral part of the software development process, helping developers to efficiently manage and execute changes in the code.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figure 1 As shown, a trusted function regression test method for a trusted DCS controller includes the following steps: Step 1: Generate and execute a regression test case set in a test case management system based on the trusted functional module of the regression test; Among them, the trusted function module of regression test and the trusted function module are deployed on the trusted DCS controller.

[0028] like Figure 2 As shown in the figure, the regression test case set is generated based on the trusted functional module of the regression test. The specific generation steps are: Deploy trusted functional modules for regression testing; Extract the changed method names in the trusted function modules for regression testing; Determine the regression test cases corresponding to all changed method names in the test case management system; All regression test cases generate regression test case sets in the test case management system.

[0029] In the above steps, the generation of regression test case sets depends on the code change extraction tool. The more detailed steps are: Use code extraction tools to extract method name information of trusted function source code in trusted function modules of regression testing; According to the code change document, obtain the changed code line information and method name information; According to the code line or method name, find the related test cases from the test case management system and generate a regression test set.

[0030] After the regression test case set is generated, the regression test case set in the test case management system can be directly called for subsequent regression testing.

[0031] a) Parse the code change document and extract the changed file name and method name; b) automatically accessing the database of the test case management system, using the method name determined in step 3a), obtaining the test case containing the method name; c) The code change tool finds the target regression test case set that needs regression testing this time from the test case management system based on the method name obtained in step 3b), automatically generates the test case set that needs regression testing in the test case management system, and pushes the test case set that needs regression testing this time to the test engineer.

[0032] Step 2: Determine whether the regression test case set has been executed. If not, continue to execute; if so, generate a regression test report.

[0033] Specifically, the process of executing the regression test case set in the test case management system is as follows: Generate regression test case sets in the test case management system using code change extraction tools; Accept and process the tested functional instructions of regression test cases, and execute regression test cases in the test case management system.

[0034] The criterion for judging whether the regression test case set has been executed is whether all the regression test cases in the regression test case set have been executed.

[0035] In another embodiment of the present invention, a complete trusted function testing method is provided, such as Figure 3 As shown: Step 1: Deploy a trusted function module on the DCS controller; Step 2: Write test cases for the controller's trusted functions according to the requirements document and trusted function manual document; Step 3: Use squish coco to monitor the trusted function module on the DCS controller, which then becomes the transformed trusted function module. The transformed function module provides the following functions: a) Receive and process the test requests in the test cases; b) squish coco will color the method names of trusted function modules according to the executed test requests; "Coloring" the method names of "trusted function modules" can be understood as squish coco being able to track and record whether these specific methods are called and executed during the test execution. The results of this tracking are usually presented in some form, such as generating a code coverage report, which will clearly indicate which methods are executed (i.e. "colored") and which methods are not executed (i.e. "uncolored").

[0036] It should be noted that this "coloring" does not directly modify or mark the method name, but is achieved through code coverage analysis technology. In actual operation, developers or testers can view the code coverage report to understand the effectiveness of the test, including which methods of trusted functional modules have been fully tested and which ones need further test cases to cover.

[0037] Step 4: The test engineer executes the test case in step 2 on the modified functional module. When executing the test case, squish coco will color the methods of the trusted functional module according to the executed test instructions, thereby collecting the colored method names corresponding to this test case; Step 5: The test engineer enters the method name corresponding to the test case into the test case management system; Step 6: When the R&D engineer submits a new trusted function installation package to add new functions or modify defects, the test engineer deploys squish coco and the new installation package of the trusted function module that needs regression testing on the DCS controller device, which is called the trusted function module for regression testing. The trusted function module for regression testing is deployed on the DCS controller; Step 7: According to the code change document provided by R&D, use the code change tool to extract the changed method names in the new trusted function installation package. The code change tool has the following functions: a) Parse the code change document and extract the changed file name and method name; b) automatically access the database of the test case management system, and use the method name determined in step 3a) to obtain the test case containing the method name; c) The code change tool finds the target regression test case set that needs regression testing this time from the test case management system based on the method name obtained in step 3b), automatically generates the test case set that needs regression testing in the test case management system, and pushes the test case set that needs regression testing this time to the test engineer; Step 8: The test engineer executes the regression test case set pushed in step 7 c) on the trusted function module of the regression test in step 6; Step 9: After executing all pushed regression test case sets, generate a regression test report.

[0038] In another embodiment of the present invention, a complete trusted function testing method is provided, which specifically includes the following steps: Step 1: Squish Coco colors the methods in the trusted function module according to the executed test instructions, collects the colored method names corresponding to the test cases, enters the method names corresponding to the test cases into the test case management system, and obtains the test case set; Use squish coco to monitor the trusted function module on the DCS controller. In the field of software communication, monitoring refers to the process of receiving, analyzing and processing the signals, data or information in the communication process in real time or non-real time through specific technical means or equipment. This process mainly relies on technical means such as network monitoring, signal interception, and data capture to achieve monitoring and control of communication content.

[0039] The general steps for code coverage analysis using Squish coco are as follows: Install Squish coco: Configure project: Configure Squish coco in the test project, including specifying the source code path, setting compiler options, etc. Build the project: Use Squish coco's CoverageScanner tool to build the project and generate the detected executable file or library; Run test: execute the test script or test set, Squish coco will track and record the code execution; Analyze reports: Use the CoverageBrowser tool to analyze the generated coverage report, find untested code sections, and optimize them if needed.

[0040] Step 2: Use a code change tool to collect method names corresponding to regression test cases, and enter the method names corresponding to the regression test cases into a test case management system to obtain a regression test case set; Step 3: The test engineer issues a command to view and execute the test case, outputs the test report, and after the test case is executed, starts to execute the regression test case command. The test case management system pushes the test case that needs regression testing to the test engineer. After the pushed regression test case is executed, the regression test report is output, and then the complete test report is output. (The complete test report includes the test report and the regression test report) The present invention also provides a trusted function regression test system for a trusted DCS controller, comprising a setting module, an execution module and a judgment module, wherein: Setting module: used to deploy trusted functional modules for regression testing; Execution module: Based on the trusted functional module of regression testing, it generates and executes regression test case sets in the test case management system; Judgment module: used to determine whether the regression test case set has been executed. If not, continue to execute; if so, generate a regression test report.
