[0037] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0039] ADAS has become a trend in the automotive industry. Under the influence of this trend, the importance of the system is increasing. At the same time, with the development and popularization of the system, users' requirements for the system are also getting higher and higher, making ADAS integrate more and more functions, such as:

[0040] ACC can sense and judge the environment in front of or around the vehicle through radar, camera, fusion map, etc., to achieve the functions of following the vehicle and cruise control; IACC (Integrated Adapted Cruise Control) is based on adaptive cruise control, and realizes lateral control within the speed range of 0-130km / h, so as to achieve a certain degree of hands-free driving under the driver's supervision; NID (Navigation Intelligent Driving Assistance) refers to the use of ALC (Auto Lane Change) and TSR (Traffic Sign Recognition) and other functions to achieve assisted driving according to the navigation planning path on the road sections covered by high-precision maps. The development of these functions makes driving simpler and more efficient, and the requirements for their functional testing are also getting higher and higher.

[0041] In the related art, the design of driving assistance function use cases is mainly implemented by test engineers based on technical documents (requirement documents, etc.); however, the design method of the related art has no mature theoretical basis, and due to the different experiences of test engineers, there are differences in the designed test cases, and the coverage of functional requirements cannot be guaranteed, which leads to safety hazards of driving assistance functions.

[0042] In view of the problems in the above background technology, the embodiments of the present application propose a method, device, electronic device and storage medium for optimizing test cases of a driving assistance system. Figure 1 A flowchart of a driving assistance system test case optimization method provided in an embodiment of the present application.

[0043] like Figure 1 As shown, the driving assistance system test case optimization method includes the following steps:

[0044] In step S101, a test case of a driving assistance system is obtained.

[0045] It is understandable that the embodiments of the present application may first acquire test cases for the driving assistance system so as to utilize the acquired test case data for analysis and optimization.

[0046] In an embodiment of the present application, obtaining a test case for a driving assistance system includes: obtaining test requirements for the driving assistance system; determining a test case template according to a test type corresponding to the test requirements; and generating one or more test cases according to the test case template.

[0047] Among them, the test types include: real vehicle system function test type and / or test bench system function test type; the test case templates include: one or more of state transition use case templates, conditional combination use case templates, boundary value use case templates and flowchart use case templates.

[0048] It is understandable that if Figure 2 As shown, the embodiment of the present application can select a test type corresponding to the test requirement according to the requirement of the driving assistance system test, determine the test case template according to the test type, and generate a corresponding test case according to the test case template.

[0049] Specifically, the state transition use case template designs test cases based on the state transition diagram generated by the transition between different states; the condition combination use case template designs test cases based on different results produced by different condition combinations; the boundary value use case template designs test cases based on the critical point values ​​of the requirements; the flowchart use case template designs test cases based on the flowchart generated by the operation process.

[0050] The following is an explanation of the process of generating test cases from the state transition class, condition combination class and boundary value class use case templates of the embodiment of the present application through three specific embodiments:

[0051] First, if Figure 3 As shown, in the embodiment of the present application, state A can be set to ACC being in Standby state, state B can be ACC being in Active working state, and state C can be ACC being in Passive state; condition A1 is that the main car door is open, condition A2 is pressing the ACC activation key, condition B1 is pressing the ACC cancel key, condition B2 is that the driver steps on the brakes, condition C1 is not input, and condition C2 is that condition A1 is restored.

[0052] 1. State migration

[0053] The state transition template can be used to design use cases based on the state transition diagram, such as Figure 3 As shown, the embodiment of the present application can generate 5 test cases according to the state transition diagram template: test case (1) is that ACC is in the Standby state, and pressing the ACC activation key jumps to the Active state; test case (2) is that ACC is in the Standby state, the main car door is open, and jumps to the Passive state; test case (3) is that ACC is in the Passive state, the main car door is closed, and jumps to the Standby state; test case (4) is that ACC is in the Active state, the driver steps on the brake, and jumps to the Passive state; test case (5) is that ACC is in the Active state, the driver presses the button to cancel ACC, and jumps to the Standby state.

[0054] 2. Conditional combination class

[0055] The conditional combination test case template can be used to design test cases based on different condition combinations, such as Figure 4 As shown, the use case design is carried out by taking condition D1, condition D2, condition D3 and result E as an example: test case (1) is when conditions D1, D2 and D3 are met at the same time, and the result is E; test case (2) is when conditions other than D1, D2 and D3 are met at the same time, and the result is other than E; test case (3) is when conditions D1, other than D2 and D3 are met at the same time, and the result is other than E; test case (4) is when conditions D1, D2 and other than D3 are met at the same time, and the result is other than E.

[0056] 3. Boundary value class use case template

[0057] The boundary value type test case template can design test cases according to the values ​​near the critical point. The embodiment of the present application can design test cases based on the variable F in the range of GH (equal), the minimum resolution is I, and the result is J as an example: test case (1) is when the variable F is equal to G, the result is J; test case (2) is when the variable F is equal to H, the result is J; test case (3) is when the variable F is equal to G+I, the result is J; test case (4) is when the variable F is equal to HI, the result is J; test case (5) is when the variable F is equal to GI, the result is not J; test case (6) is when the variable F is equal to H+I, the result is not J.

[0058] In step S102, scenario analysis is performed on the test case in one or more preset scenarios to obtain analysis results.

[0059] Among them, the preset scene can be set according to the actual situation, that is, the embodiment of the present application can design different user usage scenarios according to the needs; in the following embodiments, Figure 5 As shown, the design of the test case will be described by taking state K, state L1, state L2, scene K1, scene K2, scene K3 and scene K4 as examples.

[0060] It can be understood that the embodiments of the present application can use a scenario analysis method to design different user usage scenarios according to user needs, so that test cases can be brought into the scenarios for analysis, and the obtained analysis results are more reliable and can meet the actual needs of users.

[0061] In step S103, the erroneous activation action of the driving assistance system in the analysis result is inferred, and the test case is optimized according to the erroneous activation action.

[0062] It can be understood that the embodiment of the present application can analyze the scenario and make error inferences based on the above steps S101 and S102: the embodiment of the present application can design test cases to interrupt the demand under the premise of positive demand, test the execution under abnormal interruption, analyze the error activation action, and optimize the test case according to the error activation action, thereby covering the functional requirements more comprehensively.

[0063] In an embodiment of the present application, optimizing a test case according to an error activation action includes: generating a test interruption result according to the error activation action; and writing the test interruption result into the test case.

[0064] It is understandable that the embodiments of the present application can supplement and improve the test cases based on the scenario analysis method and the error inference (reverse) method to improve the demand coverage.

[0065] The following will describe the process of optimizing test cases based on the erroneous activation actions of the driving assistance system in the inference analysis results of the embodiment of the present application according to a specific embodiment, as follows:

[0066] For example, Figure 3 Taking the state transition diagram shown as an example, in the embodiment of the present application, state A can be set for ACC to be in Standby state, state B can be for ACC to be in Active working state, and state C can be for ACC to be in Passive state; condition A1 is that the main car door is open, condition A2 is pressing the ACC activation key, condition B1 is pressing the ACC cancel key, condition B2 is that the driver steps on the brakes, condition C1 is not input, and condition C2 is that condition A1 is restored.

[0067] Based on the above, analyze the scenario and make error inferences to design optimized use cases: Figure 5 As shown, scene K1 is the normal activation of ACC; scene K2 is the triggering of other functions that do not affect the activation during the activation process, such as turning on the air conditioner, Bluetooth, etc.; scene K3 is the continuous and rapid pressing of the ACC activation key; scene K4 is the triggering of functions that affect the activation of ACC during the activation process, such as activating APA (AutoParking Assist, automatic parking assistance system), etc.

[0068] Test cases were designed according to the scenarios: (1) normal button activation of ACC; test case (2) the driver button activated while the passenger turned on the air conditioner and Bluetooth, and ACC was activated normally; test case (3) the driver button activated ACC, the passenger canceled the activation, the driver buttoned again, and ACC was activated; test case (4) after the driver button activated ACC, he button activated APA, ACC was not activated, and APA was activated.

[0069] In summary, the driving assistance system test case optimization method proposed in the embodiment of the present application has at least the following advantages:

[0070] (1) The embodiments of the present application can perform reverse error inference and optimization based on the analysis results of driving assistance test cases in different scenarios, thereby improving the test coverage and test quality, making the test results more reliable, ensuring the safety of driving assistance functions, and meeting actual use needs;

[0072] (3) The embodiments of the present application can match corresponding test case templates according to different test requirements, and then generate test cases that meet the test requirements, thereby improving the test case matching degree, reducing the differences in test case design, and avoiding inaccurate results and waste of test resources caused by test case mismatch;

[0073] (4) The embodiments of the present application can distinguish different test types, so as to generate different test cases according to different types, improve the matching degree between test case generation and actual test, and make the test results more reliable;

[0074] (5) The embodiment of the present application can generate test cases using at least one test case template, thereby improving the test case matching degree, reducing the differences in test case design, and further improving the reliability of test case generation to meet actual usage needs;
