Technical Field

The present invention relates to the technical field of module function testing, and in particular to a testing method and system based on electronic control module functions.

Background Art

In recent years, with the development of hardware-software collaborative design and testing technology, some new test methods based on the functions of electronic control modules have begun to attract attention. These methods use simulation technology, model-driven testing and artificial intelligence algorithms to achieve comprehensive and accurate testing of the functions of electronic control modules. At present, electronic control modules play a key role in various industrial and consumer electronic devices, and are used to manage and control the various functions of the equipment. However, traditional electronic control module function testing methods often mainly include manual testing and automated testing. Among them, manual testing relies on the experience and skills of the operator, and often has problems such as inconsistent functional test results and low test efficiency; while automated testing improves test efficiency, it often cannot fully cover all possible usage scenarios and functional modules, resulting in insufficient test coverage and low test accuracy.

Summary of the invention

Based on this, it is necessary for the present invention to provide a testing method and system based on the function of an electronic control module to solve at least one of the above technical problems.

To achieve the above object, a test method based on the function of an electronic control module comprises the following steps:

Step S1: performing test requirements and target identification analysis on the electronic control module function to obtain electronic control module function test requirement data and electronic control module function test target data; performing function test point key mining analysis on the electronic control module function based on the electronic control module function test requirement data and the electronic control module function test target data to obtain the key function points to be tested of the electronic control module;

Step S2: classifying and designing test cases for key function points to be tested in the electronic control module based on the electronic control module function test requirement data to obtain a classification set of electronic control module function test cases; constructing an electronic control module function test environment, and automatically testing and processing the classification set of electronic control module function test cases based on the electronic control module function test environment to obtain test output results of the electronic control module function under different working conditions;

Step S3: Based on the test output results of the electronic control module function under different working conditions, test evaluation fault analysis is performed on the key functional points of the electronic control module to be tested, so as to obtain the electronic control module function test fault problem points; fault repair feedback analysis is performed on the electronic control module function test fault problem points, so as to generate the electronic control module function test fault repair strategy plan;

Step S4: Performing a test fault repair process on the electronic control module function according to the electronic control module function test fault repair strategy and generating an electronic control module function test process repair report.

The present invention firstly analyzes the function test requirements of the electronic control module function, and can identify the specific test requirements of each function point, including necessary input conditions, expected output results, and various boundary conditions and special cases involved, which ensures that all aspects of the module function can be covered in the test phase, thereby improving the comprehensiveness and accuracy of the test. By performing functional test target identification analysis on the electronic control module function, the test target of each function point can be clarified, including determining the main purpose of the test, the expected test effect, and possible test methods and strategies. This analysis helps to ensure that the goals of the test activities are clear and efficient, and provides direction for the subsequent marking and key mining of functional test points. At the same time, by performing key mining analysis of the function test points of the electronic control module function based on the electronic control module function test requirement data and the electronic control module function test target data, the core of this step is to identify and determine the key function points of the module to be tested, that is, those test points that have the most significant impact on the module performance and functional characteristics. Through key mining analysis, these key function points can be given priority and focused on testing to ensure that the core part of the electronic control module function can be properly covered and verified in the test, thereby improving the coverage rate of the electronic control module function test process. Secondly, by classifying and designing the test cases for the key functional points to be tested of the electronic control module based on the functional test requirement data of the electronic control module, the test case classification is designed for the key functional points to be tested. The key to this step is to ensure the comprehensiveness and coverage of the test cases, so as to cover all important functional aspects and classify and design for different functions. Through classification design, the test cases can be effectively organized and managed to ensure that the correctness and performance of each functional point can be efficiently executed and verified in the subsequent test process. This detailed classification design not only helps to improve the accuracy and comprehensiveness of the test, but also provides a clear execution guide and basis for the subsequent test process, and eliminates the problem of inconsistent test results. By building a corresponding functional test environment according to the functional test equipment and test software of the electronic control module, the key to this step is to ensure that the test environment is fully prepared and perfect to support subsequent functional test activities. By obtaining appropriate test equipment and software, the real-time and accuracy of the test process can be ensured, and a stable and reliable test platform can be provided for the verification of module functions. Building a test environment not only helps to reduce environment-related problems in the test process, but also improves the consistency and repeatability of the test, thereby ensuring the validity and reliability of the test results. By using the built electronic control module functional test environment, the previously designed test case classification set is automatically tested. The key to this step is to use automated testing technology to achieve comprehensive coverage and efficient execution of functional test cases. Through automated processing, a large amount of test data and results can be quickly obtained, thereby achieving a comprehensive evaluation of the performance and stability of the electronic control module function under different working conditions. The output results of the automated test can not only provide timely feedback on the execution status and results of the test, but also provide data support and basis for subsequent problem analysis and improvement, thereby improving the test efficiency and test accuracy of the electronic control module function. Then, by testing and evaluating the key functional points of the electronic control module to be tested based on the test output results of the electronic control module function under different working conditions, the specific fault problem points can be quickly located and confirmed, laying the foundation for problem solving. By performing fault repair feedback analysis on the fault problem points of the electronic control module function test, this process is not just a simple repair problem, but more importantly, by analyzing the problem source data, the urgency and priority of fault repair can be understood. During the analysis process, factors such as time, resources and costs need to be considered in order to develop a reasonable and effective fault repair strategy. This analysis can ensure the effectiveness and long-term stability of the repair work, thereby minimizing the occurrence of similar problems in the future. Finally, the electronic control module function is systematically tested and repaired according to the electronic control module function test fault repair strategy. This process not only includes technical repairs to specific fault points, but also covers the generation and recording of test process repair reports. The key to this repair process stage is to ensure that the repair operation meets the design requirements and expected results, and to verify the repair effect and the stability of the system after the repair through strict test verification and feedback loops. The test process repair report finally generated is not only a document record of problem solving, but also a summary and evaluation of the entire repair process, thereby providing experience and reference for dealing with similar problems in the future.

The embodiment of the present invention collects and organizes various functional descriptions of the electronic control module, which are derived from system design documents, functional specifications or specific functional details provided by the development team, and extracts specific descriptors describing the functions of the electronic control module. At the same time, by using requirements analysis tools or technologies (such as requirements tracking matrix, use case analysis, scenario modeling and other methods), a detailed functional test requirements analysis is performed on the corresponding functional descriptors to understand the specific test requirements that each functional descriptor needs to meet, including verifying whether the function works as expected, whether the system response meets the specification, and the correctness of the functional operation, thereby obtaining the electronic control module functional test requirement data. Secondly, by combining the electronic control module functional test requirement data obtained by the analysis, the corresponding functional descriptors are planned and analyzed for test targets, so as to fully consider the importance of system functions, the dependencies between modules and the expected test coverage to determine the test targets of each electronic control module functional descriptor, including test targets in terms of correctness verification of functional operation, testing of boundary conditions, handling of abnormal situations, etc., thereby obtaining the electronic control module functional test target data. Then, by using a special functional test point marking tool or a test management system, the functional test points of the corresponding electronic control module functions are marked according to certain standards or guidelines to extract specific test points, and by combining the electronic control module functional test requirement data and the electronic control module functional test target data obtained by analysis, the previously marked functional test points are mined and analyzed using a key mining analysis method to comprehensively consider the feasibility and importance of the functional test points to identify and determine the key functional points to be tested in the electronic control module, and finally obtain the key functional points to be tested in the electronic control module.

Step S2: classifying and designing test cases for key function points to be tested in the electronic control module based on the electronic control module function test requirement data to obtain a classification set of electronic control module function test cases; constructing an electronic control module function test environment, and automatically testing and processing the classification set of electronic control module function test cases based on the electronic control module function test environment to obtain test output results of the electronic control module function under different working conditions;

The embodiment of the present invention describes in detail the functions and performance requirements that the electronic control module should have under different working conditions by carefully reviewing the electronic control module or product specifications and requirements documents in combination with the electronic control module functional test requirement data obtained through analysis, and designs corresponding test cases for the key functional points of the electronic control module to be tested according to its requirements under different operating conditions, including functional test cases under normal operating conditions, test cases under abnormal conditions, and test cases under boundary conditions, thereby obtaining a classification set of electronic control module functional test cases. At the same time, the functional test environment of the electronic control module is built by obtaining the required electronic control module functional test equipment and corresponding functional test software, which includes configuring the connection and interface of the hardware equipment, installing and setting the functional test software, and ensuring that the entire test environment can accurately simulate the working conditions and operating environment of the electronic control module in actual applications, thereby building an electronic control module functional test environment. The established electronic control module functional test environment is also used to write automated test scripts for the previously designed electronic control module functional test case classification set, so as to realize the automatic execution and automatic verification of various designed test cases, and use appropriate automated testing tools or scripting languages to write specific test scripts according to the functional test requirements and the designed test cases, including simulation of input conditions, execution of operation steps, verification of output results and other logic, to realize the actual automated testing of different functional test cases in the electronic control module functional test case classification set, and combine the automated testing tool to automatically execute the test cases according to the pre-set test conditions and scripts, and collect the corresponding test output results, which include the execution status of each test case, the comparison results of the actual output and the expected output, the response time of the system, and the errors and abnormal conditions that occur during the test, and finally obtain the test output results of the electronic control module function under different working conditions.

Step S3: Based on the test output results of the electronic control module function under different working conditions, test evaluation fault analysis is performed on the key functional points of the electronic control module to be tested, so as to obtain the electronic control module function test fault problem points; fault repair feedback analysis is performed on the electronic control module function test fault problem points, so as to generate the electronic control module function test fault repair strategy plan;

The embodiment of the present invention collects and records the functional test results of the key functional points to be tested of the electronic control module under various predetermined working conditions by combining the test output results of the electronic control module function under different working conditions obtained by analysis, including sensor feedback, actuator response, internal processing data, etc., and analyzes the test output results at the key functional points to be tested by using an abnormality evaluation algorithm to check and analyze the abnormal conditions appearing in these test output results, and analyzes the monitored test abnormal conditions by using tools such as fault diagnosis software, logic analyzer, failure mode and effects analysis (FMEA), so as to identify and confirm specific fault problem points according to the test abnormal conditions recorded in the previous steps, and extract key clues and patterns from the existing test data to determine which abnormalities are systematic problem points and which are sporadic fault problem points, thereby obtaining the fault problem points of the electronic control module function test. Then, by reviewing relevant design documents, prototype test reports, hardware circuit diagrams, and software source codes, the specific causes and mechanisms leading to the identified electronic control module functional test fault problem points are deeply analyzed, and the origin of each fault point and the root cause of the fault are traced back. In addition, by combining the root cause of the fault problem obtained in the previous analysis, a strategic feedback analysis of the repair process is performed on the corresponding electronic control module functional test fault problem points, so as to formulate a detailed fault repair strategy plan by fully considering the balance between impact and cost-effectiveness, including determining the hardware components that need to be modified or replaced, optimizing the software algorithm or logic, and retesting and verifying the repaired module functions, etc., and ensuring that the repair measures will not introduce new problems or affect other functions of the module, and finally generate an electronic control module functional test fault repair strategy plan.

Then, by designing and generating corresponding exception handling test cases based on the demand data of the electronic control module under abnormal handling conditions, the key to this step is to simulate and verify the response and processing capabilities of the electronic control module when facing various abnormal inputs or operations. Each exception handling test case needs to describe in detail the triggering mode of the abnormal conditions, the expected system response and the countermeasures to ensure that the module can correctly detect, handle and recover errors under abnormal conditions. Through careful design and generation, the robustness and safety of the system can be effectively evaluated, potential errors and security vulnerabilities can be discovered, and the reliability and stability of the electronic control module function can be improved. Next, by designing and generating corresponding boundary condition test cases based on the demand data of the electronic control module under boundary conditions, the key to this step is to verify the behavior and system response of the electronic control module under the extreme conditions of input or operation. Each boundary condition test case needs to define the boundary value of the input, the expected response and output of the system in detail to ensure that the module can operate normally or fail reasonably under extreme conditions and will not cause system crash or damage. Through rigorous design and generation, the stability of the electronic control module and its robustness under extreme conditions can be effectively evaluated, providing important feedback and improvement suggestions for the design and implementation of the electronic control module. Finally, the normal function test cases, exception handling test cases, and boundary condition test cases of the electronic control module are merged to form a complete functional test case classification set. The key to this step is to integrate and manage all designed test cases to ensure that various functional scenarios and test requirements are covered. Through the merging of cases, the test case collection can be effectively organized and managed, providing clear guidance and operational basis for subsequent test execution and evaluation. The integrated functional test case classification set can not only ensure comprehensive coverage of various test situations, but also provide the test team with efficient execution paths and test strategies, ultimately ensuring the stability and functional integrity of the electronic control module under various circumstances.
