[0070] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0071] This article provides a solution for automatically generating test cases by extracting vehicle control rules in natural language from requirement documents, including input and output signal extraction, control logic extraction, and signal value range sampling. Then, the solution is combined with automatic test case generation to shorten the test case writing process and improve the test case writing efficiency.

[0072] Figure 1 Flow chart of a test case generation method in one embodiment of the present application, such as Figure 1 As shown, the method can be implemented as the following steps S101-S104:

[0073] In step S101, a requirement document including vehicle control requirements is obtained;

[0074] In step S102, signal information corresponding to the vehicle control requirement is obtained from the requirement document, and an assignment rule corresponding to the vehicle control requirement is obtained from the requirement document, wherein the assignment rule includes a conditional expression and an action expression;

[0075] In step S103, the signal value interval of the signal information corresponding to the vehicle control demand is extracted through the conditional expression and the action expression in the assignment rule;

[0076] In step S104, a target test case including the signal value interval is generated.

[0077] In this application, a requirement document containing vehicle control requirements is obtained; first, a user Token is obtained, and then a third-party API (application programming interface) is accessed based on the user Token to obtain a specific requirement document from the knowledge base, and the requirement details in the requirement table are extracted from the requirement document. Figure 2 This is a schematic diagram of a requirement document for vehicle control requirements in one embodiment of the present application, such as Figure 2 As shown, the requirement document includes three parts: requirement definition, input signal and output signal. The requirement definition includes the correspondence between the test logic of the test case and the input and output values. The input signal includes the input signal name, signal value type and signal value range of the test case. The output signal includes the output signal name, signal value type and signal value range of the test case.

[0078] After the requirement document is obtained, signal information corresponding to the vehicle control requirement is obtained from the requirement document, and an assignment rule corresponding to the vehicle control requirement is obtained from the requirement document, wherein the assignment rule includes a conditional expression and an action expression.

[0079] When acquiring the signal information corresponding to the vehicle control requirement from the requirement document, the first signal information contained in the requirement document is extracted, that is, the original signal information in the requirement document is extracted, such as Figure 2 As shown, the input signal and output signal parts are extracted. Secondly, the characters in the first signal information are converted into characters in a preset format to obtain the second signal information. Specifically, the special characters in the first signal information are removed, such as uniformly replacing Chinese full-width and half-width symbols and English symbols, unifying units, removing useless information, and unifying redundant expressions, etc., so as to convert the first signal into a second signal information with a unified format. Then, at least one of the following attribute items in the second signal information is obtained: signal statement, signal name, signal enumeration value, signal domain value; as Figure 2 As shown, the signal statement "RESts_Inner (M) Range Extender Working Status (X Platform)" can be extracted; the signal name can be extracted: RESts_Inner; the signal enumeration value can be extracted: such as: {0x0: Off, 0x1: Start, 0x2: Run, 0x3: Stop, 0x4: Stall}; the signal range can be extracted: the signal value range of the RESCur signal can be [-2500, 2500]. Finally, the attribute items are combined into the signal information corresponding to the vehicle control demand. Specifically, the combined signal information can be expressed in the form of a table, for example, it can be expressed in the form of the following Table 1.

[0080] Table 1 Signal information table corresponding to vehicle control requirements

[0081]

[0082] When obtaining the assignment rules corresponding to the vehicle control requirements from the requirement document, the original assignment rules in the requirement document can be obtained; the original assignment rules in the requirement document are converted into the assignment rules corresponding to the vehicle control requirements. Specifically, when converting the original assignment rules in the requirement document into the assignment rules corresponding to the vehicle control requirements, the original assignment rules can be standardized; the conditional expressions and action expressions in the standardized original assignment rules are extracted; and the assignment rules corresponding to the vehicle control requirements containing the conditional expressions and action expressions are generated.

[0083] When standardizing the original assignment rules, the special characters in the original assignment rules are standardized, the logical relationship words in the original assignment rules are converted into preset words with the same meaning as the logical relationship words, and the Chinese operators in the original assignment rules are converted into standard operators.

[0084] The conditional expressions and action expressions contained in the assignment rules are explained through the following examples:

[0085] For example, in the assignment rule, there is a statement like this: if a==1&&b==2, then c=3, otherwise c=4. Then "a==1&&b==2" between the logical conjunctions if and then is a conditional expression, and "c=3" and "c=4" are action expressions.

[0086] After obtaining the signal information corresponding to the vehicle control requirement from the requirement document and obtaining the assignment rule corresponding to the vehicle control requirement from the requirement document, the signal value interval of the signal information corresponding to the vehicle control requirement is extracted through the conditional expression and action expression in the assignment rule.

[0087] Specifically, when the signal information is an input signal and the signal domain value defined by the input signal is a discrete value, the discrete value is traversed through the conditional expression in the assignment rule; and the value in the discrete value that matches the conditional expression is determined to be the signal value interval of the signal information corresponding to the vehicle control requirement.

[0088] In addition, it should be noted that when the signal information is an input signal and the signal domain value defined by the input signal is a value range, the span of the value range can be obtained. When the span of the value range is small, the value range can also be traversed through the conditional expression in the assignment rule to filter out signal values ​​that meet the conditional expression as the signal value range of the signal information corresponding to the vehicle control requirement.

[0089] Since the ultimate goal of this application is only to generate test cases to test whether the architecture functions normally, only a limited number of test cases are needed to complete the test, and there is no need to exhaustively list all situations. When the span of the value interval is large, if it is traversed, a large number of test cases will be generated, which does not meet the original intention of the test. Therefore, when the span of the value interval is large, the maximum value, second largest value, middle value, second smallest value and minimum value of the value interval can be taken as the signal value interval of the signal information corresponding to the vehicle control demand, wherein the span size of the value interval can be measured by the number of integers in the value interval. That is to say, when the signal information is an input signal, and the signal domain value defined by the input signal is a value interval, the method can also be implemented as the following steps:

[0090] When the number of integers in the value interval is less than a preset number, the value interval is traversed through the conditional expression in the assignment rule, and the signal values ​​that meet the conditional expression are screened out as the signal value interval of the signal information corresponding to the vehicle control demand.

[0091] When the number of integers in the value interval is greater than a preset number, the maximum value, the second largest value, the middle value, the second smallest value and the minimum value of the value interval are determined as the signal value interval of the signal information corresponding to the vehicle control demand.

[0092] Specifically, at least one intermediate value may be determined by at least one of the following formulas:

[0093] Middle value = minimum value + (maximum value - minimum value) / 2;

[0094] Middle value = maximum value - (maximum value - minimum value) / 2.

[0095] It should also be noted that when the value interval corresponding to the signal domain value is open or closed, or when the value interval corresponding to the signal domain value has multiple non-continuous value intervals, the generated value may fall outside the interval. Therefore, after calculating the maximum value, second largest value, middle value, second smallest value and minimum value, a secondary judgment is required to determine whether these values ​​fall outside the interval. If they fall outside the interval, they are discarded. If they fall within the interval, they are used as the signal value interval of the signal information corresponding to the vehicle control requirement.

[0096] After extracting the signal value interval of the signal information corresponding to the vehicle control requirement through the conditional expression and the action expression in the assignment rule, a target test case containing the signal value interval is generated, and the target test case mainly includes each signal value interval. In this way, the construction of the test case is completed. In addition, after the target test case is generated, a configuration file containing the target test case and the action expression can be generated to realize the automatic running of the test case on the device.

[0097] The beneficial effects of the present application are: obtaining a requirement document containing vehicle control requirements; obtaining the signal information corresponding to the vehicle control requirements and the corresponding assignment rules from the requirement document, wherein the assignment rules contain conditional expressions and action expressions; then, extracting the signal value interval of the signal information corresponding to the vehicle control requirements through the conditional expressions and action expressions in the assignment rules; and then automatically generating a target test case containing the signal value interval. Since the signal information and the corresponding assignment rules can be directly obtained from the vehicle control requirement document, and the signal value interval can be automatically extracted to generate a test case, there is no need for developers to manually write test cases, which shortens the test case writing cycle and improves the test case writing efficiency.

[0098] In one embodiment, the step S102 of acquiring the signal information corresponding to the vehicle control requirement from the requirement document may be implemented as the following steps A1-A4:

[0099] In step A1, extracting first signal information contained in the requirement document;

[0100] In step A2, characters in the first signal information are converted into characters in a preset format to obtain second signal information;

[0101] In step A3, at least one of the following attribute items in the second signal information is obtained:

[0102] Signal statement, signal name, signal enumeration value, signal domain value;

[0103] In step A4, the attribute items are combined into signal information corresponding to the vehicle control requirement.

[0104] In this embodiment, the first signal information contained in the requirement document is extracted, that is, the original signal information in the requirement document is extracted, such as Figure 2 As shown, the input signal and output signal parts are extracted.

[0105] Secondly, the characters in the first signal information are converted into characters in a preset format to obtain the second signal information. Specifically, the special characters in the first signal information are removed, such as replacing Chinese full-width and half-width symbols and English symbols, unifying the units, removing useless information, and unifying redundant expressions, thereby converting the first signal into the second signal information with a unified format.

[0106] Then, at least one of the following attribute items in the second signal information is obtained: signal statement, signal name, signal enumeration value, signal domain value; Figure 2 As shown, the signal statement "RESts_Inner (M) Range Extender Working Status (X Platform)" can be extracted; the signal name can be extracted: RESts_Inner; the signal enumeration value can be extracted: such as: {0x0: Off, 0x1: Start, 0x2: Run, 0x3: Stop, 0x4: Stall}; the signal range can be extracted: the signal value range of RESSCur signal is [-2500, 2500].

[0107] Finally, as shown in Table 1, the attribute items are combined into signal information corresponding to the vehicle control demand.

[0108] Table 1 Signal information table corresponding to vehicle control requirements

[0109]

[0110]

[0111] In one embodiment, the step S102 of obtaining the assignment rule corresponding to the vehicle control requirement from the requirement document may be implemented as the following steps B1-B2:

[0112] In step B1, the original assignment rule in the requirement document is obtained;

[0113] In step B2, the original assignment rules in the requirement document are converted into assignment rules corresponding to the vehicle control requirements.

[0114] In this embodiment, the original assignment rules in the requirement document are obtained, that is, the original assignment rules described in the requirement definition are extracted from the requirement document. Then, the original assignment rules in the requirement document are converted into assignment rules corresponding to the vehicle control requirements, that is, formalized into assignment rules that can be understood by a computer.

[0115] In one embodiment, the above step B2 may be implemented as the following steps B21-B23:

[0116] In step B21, the original assignment rule is standardized;

[0117] In step B22, the conditional expression and action expression in the standardized original assignment rule are extracted;

[0118] In step B23, an assignment rule corresponding to the vehicle control requirement including the conditional expression and the action expression is generated.

[0119] In one embodiment, the above step B21 may be implemented as follows:

[0120] The special characters in the original assignment rules are standardized, the logical relationship words in the original assignment rules are converted into preset words with the same meaning as the logical relationship words, and the Chinese operators in the original assignment rules are converted into standard operators.

[0121] like Figure 2As shown, since the vehicle control requirement rules in the requirement document are written by testers in natural language, there are inconsistencies in the terms, and the original assignment rules need to be standardized. Specifically, it includes standardizing the special characters in the original assignment rules, such as uniformly replacing Chinese full-width and half-width symbols and English symbols; it also includes converting the logical relationship words in the original assignment rules into preset words with the same meaning as the logical relationship words, such as converting "when, if" to "if", "not for" to "not equal to", "not meeting the above conditions" to "otherwise", etc.; in addition, it also includes converting the Chinese operators in the original assignment rules into standard operators, for example, converting Chinese operators such as "greater than or equal to" and "less than or equal to" into standard operators.

[0122] For example, when standardizing the special characters in the original assignment rules, Chinese full-width and half-width symbols and English symbols can be uniformly replaced. For another example, when converting the logical relationship words in the original assignment rules into preset words with the same meaning as the logical relationship words, "when" and "if" can be uniformly converted into the preset word "if"; "not for", "not" and the like are converted into the preset word "not equal to"; "does not meet the above conditions" is converted into the preset word "otherwise"; for another example, when converting the Chinese operators in the original assignment rules into standard operators, "the value of xxx is 1 or 2 or 3" can be converted into xxx==1||xxx==2||xxx==3.

[0123] In one embodiment, the signal information includes information of the input signal and information of the output signal. The above step S103 can be implemented as the following steps C1-C2:

[0124] In step C1, when the signal information is an input signal, and the signal domain value defined by the input signal is a discrete value, a traversal operation is performed on the discrete value through a conditional expression in an assignment rule;

[0125] In step C2, it is determined that the value matching the conditional expression in the discrete values ​​is a signal value interval of the signal information corresponding to the vehicle control requirement.

[0126] In one embodiment, the method can also be implemented as the following steps D1-D2:

[0127] In step D1, a target test case is obtained;

[0128] In step D2, a configuration file including the target test case is generated.

[0129] In this embodiment, the generated target test case is obtained, and then, according to the requirements of the case execution engine, a configuration file containing the target test case is generated, for example, an ini (initialization file) file is generated.
