[0045] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0046] According to one aspect of an embodiment of the present invention, a function testing method is provided.

[0047] Figure 1 FIG. 1 is a schematic diagram of the main flow of the method for function testing of an embodiment of the present invention. Figure 1 As shown, the method of function testing includes:

[0048] Step S101: according to the parameter samples of each input parameter in the function to be tested, expand the value of each input parameter to obtain the value set of the input parameter;

[0049] Step S102: determining each parameter combination of the function to be tested according to each value set of the input parameter;

[0050] Step S103: testing the function to be tested according to the various parameter combinations.

[0051] Optionally, based on parameter samples of each input parameter in the function to be tested, the value of each input parameter is expanded, including: based on parameter samples of each input parameter in the function to be tested, expanding each input parameter to at least one of the following values: null value, random value, boundary value, preset value.

[0052] Among them, parameter samples play a vital role in software testing. They refer to the input parameter examples provided by users in order to test a function. Take the function to be tested f(p1, p2) as an example, where p1 and p2 are the two parameters of the function, and the specific values ​​of p1 and p2 provided by the user constitute the parameter sample. In actual testing, we are often not satisfied with testing only a single parameter sample, because such a test has a limited scope and it is difficult to find potential defects. Therefore, we need to expand the parameter sample, that is, expand the value of each parameter so that it can cover more test scenarios.

[0053] Among them, a function is a block of code that performs a specific task. It receives certain inputs (parameters), performs specific operations or calculations, and returns outputs (return values). Functions usually consist of the following parts:

[0054] 1) Function name: used to identify the function so that it can be used when calling it in the code;

[0055] 2) Parameters: data required by the function when executing;

[0056] 3) Function body: the actual code logic of the function, consisting of several statements;

[0057] 4) Return value: the result after the function body code is executed.

[0058] Among them, null values ​​are boundary values, random values ​​are intended to simulate real business situations as much as possible and traverse more scenarios. The number of function input parameters is user-defined and usually does not exceed 5 according to the specification.

[0059] Optionally, according to the parameter samples of each input parameter in the function to be tested, the value of each input parameter is expanded, including: according to different input parameter data types, more abundant input parameter values ​​are expanded, exemplarily:

[0060] 1) Numeric type: For floating-point numbers, the value range is expanded to include positive numbers, negative numbers, zero, maximum values, minimum values, and minimum precision values; for integers, the value range is expanded to include positive integers, negative integers, zero, maximum values, and minimum values;

[0061] 2) String type: Extend the value length, including empty string, short string, long string, etc.; extend special characters, such as space, tab, newline, special symbols, etc.; extend regular expressions, such as strings containing specific characters and specific formats, etc.;

[0062] 3) Object type: Expand the combination of object attributes, such as empty attribute value, specific attribute value, specific relationship between attribute values, etc.; expand the value of nested objects, such as attribute values ​​of nested objects, relationship between nested objects, etc.

[0063] The function testing method of this embodiment performs more comprehensive parameter expansion for different data types, and can generate richer test cases, thereby improving the coverage and testing efficiency of test cases, effectively discovering potential defects, and improving software quality.

[0064] Optionally, each parameter combination of the function to be tested is determined according to the value set of each input parameter, including: according to the value set of each input parameter, all input parameters in the function to be tested are arranged and combined to obtain each parameter combination of the function to be tested.

[0065] Optionally, determining each parameter combination of the function to be tested according to the value set of each input parameter includes: analyzing each input parameter, identifying the dependency relationship between the input parameters, and determining the parameter combination based on the relationship between the input parameters, for example:

[0066] 1) Combination strategy based on logical relationship: Design parameter combination strategy based on the logical relationship between input parameters;

[0067] 2) Combination strategy based on state association: Design parameter combination strategy based on the association between input parameters and internal state of the function.

[0068] For example, suppose there is an order processing function of an e-commerce platform. The input parameters of the function are: product ID, quantity, delivery address, and payment method. The relationship between the parameters is as follows:

[0069] Product ID and quantity: The product ID must exist in the database, and the quantity cannot exceed the inventory;

[0070] Delivery address: It must comply with the format specifications, such as including province, city, district, street, postal code, etc.

[0071] Payment method: You need to select a valid payment method.

[0072] The combination strategy based on logical relations is:

[0073] The product ID does not exist, the quantity is arbitrary, the delivery address is arbitrary, and the payment method is arbitrary (test exception handling);

[0074] The product ID exists, the quantity exceeds the inventory, the delivery address is arbitrary, and the payment method is arbitrary (testing insufficient inventory);

[0075] The product ID exists, the quantity is legal, the delivery address format is incorrect, and the payment method is arbitrary (the test address format is incorrect);

[0076] The product ID exists, the quantity is legal, the delivery address format is correct, and the payment method does not exist (test payment method error);

[0077] Combined strategy based on state association:

[0078] The product ID exists, the quantity is legal, the delivery address format is correct, the payment method exists, and the payment is successful (testing the normal process);

[0079] The product ID exists, the quantity is legal, the delivery address format is correct, the payment method exists, and the payment fails (test payment failed).

[0080] In this embodiment, by analyzing the dependencies between parameters and designing a more reasonable parameter combination strategy, more effective test cases can be generated, thereby improving the coverage and test efficiency of test cases, effectively discovering potential defects, and improving software quality.

[0081] Optionally, testing the function to be tested according to the various parameter combinations includes:

[0082] Determine the expected test link corresponding to each of the parameter combinations to obtain an expected test link set;

[0083] Detect the function to be tested according to the various parameter combinations, and generate an access link set according to the test links corresponding to the parameter combinations with successful detection results;

[0084] By comparing the expected test link set and the access link set, a test result of the function to be tested is obtained.

[0085] The test link refers to the code flow that is triggered by a specific parameter combination during the function testing process. The function starts from the entry and goes through a series of internal judgments, loops, calls and other logical operations until the function is executed or the result is returned.

[0086] The step of detecting the function to be tested according to the various parameter combinations includes: detecting the function to be tested by using a backtracking algorithm according to the various parameter combinations.

[0087] Figure 2 A schematic diagram showing a main process of obtaining a function test result that can be applied to an embodiment of the present invention;

[0088] like Figure 2 As shown, first determine the expected test link corresponding to each parameter combination to obtain the expected test link set, and before determining the expected test link set, initialize the access link set to be empty, wherein the access link set is the set of test links corresponding to the parameter combination that has been successfully detected;

[0089] The function to be tested is called according to each parameter combination and the test result is recorded. If the test result returns an error (for example: function execution exception, function return error type), the error information is recorded and the current parameter combination is skipped, and the subsequent parameter combinations are continued to be executed. The test link corresponding to the parameter combination with the detection result of successful detection is added to the access link set, and the values ​​of at least part of the input parameters in the parameter combination that failed to detect are adjusted. Then, the function to be tested is tested again according to each parameter combination, and multiple parameter combinations are traversed, and the test is continuously performed (some parameters are prepared in advance, and it is believed that these parameters can be executed to this expected test link, but they are not executed). When all possible parameter combinations have been traversed and the expected test link cannot be executed, it means that there may be a problem with the function code. This result is fed back to the user, and the user is required to check whether there is a problem with the code. When the detection result corresponding to a certain parameter combination is successful detection, it is added to the access link set, and the expected test link set and the access link set are compared to obtain the test result of the function to be tested. The entire testing process does not require human intervention, and automated testing is realized.

[0090] Optionally, obtaining the test result of the function to be tested by comparing the expected test link set with the access link set comprises the following steps:

[0091] 1) Determine the sub-links and key nodes in the function to be tested based on the business logic and internal implementation of the function;

[0092] 2) Use various parameter combinations to test the function to be tested, and record the link information accessed during the test, including: function call sequence, parameter values, return values, and key nodes passed during execution, to obtain the access link set;

[0093] 3) After obtaining the access link set, compare it with the expected test link set. In addition to comparing the integrity of the entire link, you can also pay attention to the matching of sub-links, for example, check whether a sub-link appears in the access link set and whether the key nodes are correctly accessed. If a sub-link or key node mismatch is found, further analysis is required, which may be due to insufficient test case design, incorrect code implementation, or improper test environment configuration.

[0094] 4) Generate a detailed test report based on the comparison results, indicating which sub-links or key nodes are not covered or failed to match, and provide targeted feedback suggestions to guide developers to modify the code or optimize the test cases.

[0095] Among them, a sub-link is a series of interrelated code paths or fragments of execution steps passed during the function execution process. A complete link can be regarded as composed of multiple sub-links, and the sub-links can be divided based on the function's calling relationship, control flow structure or data dependency relationship; the key node is the execution point or judgment point in the function execution link that has an important influence or is decisive for the test results. The key node can be a location with a significant impact, such as function call, conditional judgment, loop structure, etc.

[0096] In this embodiment, sub-link matching can more accurately identify the differences between links, improve the accuracy and effectiveness of the test, and by focusing on sub-links and key nodes, the internal logic and potential problems of the function can be better understood.

[0097] Optionally, detecting the function to be tested according to the various parameter combinations includes: detecting the function to be tested using a retry mechanism according to the various parameter combinations, exemplarily:

[0098] Determine the relevant parameters of the retry mechanism, such as the maximum number of retries, retry interval, etc. For each parameter combination, perform the following steps:

[0099] 1) Call the function to be tested for the first time, pass in the current parameter combination, and get the call result;

[0100] 2) Check the call result. If the function to be tested throws an exception or returns an error status, enter the retry process;

[0101] 3) Set the maximum number of retries and the retry interval, call the function to be tested again, and pass in the current parameter combination to check whether the maximum number of retries has been reached. If not, wait for the specified retry interval and call the function to be tested again. Repeat the above steps until the test is successfully completed or the maximum number of retries has been reached.

[0102] 4) Regardless of whether the test succeeds or fails (after reaching the maximum number of retries), the test results are recorded, including success / failure status, time consumption, exception information, etc.

[0103] 5) Based on the test results, optimize parameters such as the maximum number of retries and retry interval.

[0104] Among them, setting the maximum number of retries can prevent infinite loops and needs to be set according to the specific application scenario. Setting the retry interval (the waiting time between each retry) can help reduce the pressure on system resources and may avoid the system avalanche effect caused by too frequent retries. The retry interval can be fixed or adjusted as needed.

[0105] Optionally, the method further includes: after testing the function to be tested according to the various parameter combinations, in response to the presence of a parameter combination that fails to be detected, adjusting the values ​​of at least some input parameters in the parameter combination that fails to be detected, and then testing the function to be tested again according to the various parameter combinations, wherein the adjustment strategy includes:

[0106] 1) Adjustment based on experience: Based on experience, select appropriate parameter values ​​for adjustment;

[0107] 2) Rule-based adjustment: select appropriate parameters for adjustment according to preset rules;

[0108] 3) Adjustment based on machine learning: Use machine learning algorithms to automatically learn the test case generation rules and make adjustments based on the learning results. For example:

[0109] Collect all parameter combinations that failed to be detected and the corresponding test results, extract features from these parameter combinations, such as parameter type, value range, value type, etc., select appropriate machine learning algorithms (such as decision trees, random forests, neural networks, etc.), use the extracted features to train the machine learning model to predict whether a new parameter combination may lead to a detection failure, and intelligently generate adjustment parameters based on the model's prediction results to continue function testing. This embodiment uses the parameter samples provided by the user to expand the values ​​of the input parameters, obtain a set of values ​​for the input parameters, determine each parameter combination, and use each parameter combination to test the function. It can comprehensively test all links of the function, ensure that every possible test link is covered, automatically analyze the parameter combination that failed to be detected, intelligently generate parameter adjustment suggestions, and retest the function using the intelligently generated parameters until it is fully covered.

[0110] Figure 3 A schematic diagram showing the main flow of a test order processing function to which an embodiment of the present invention can be applied;

[0111] like Figure 3As shown in the figure, an e-commerce platform has an order processing function processOrder, which is responsible for receiving user order requests and performing a series of operations such as creating orders, deducting inventory, and calculating shipping costs. The processOrder function receives multiple parameters, such as product ID, quantity, delivery address, etc.

[0112] The developer provides several typical order processing parameter samples, including valid order parameters and some edge cases, such as the product ID does not exist, the quantity is zero, etc., and then expands the value of each input parameter to obtain the value set of the input parameter;

[0113] Determine each parameter combination of the function to be tested according to the value set of each input parameter;

[0114] Testing the function to be tested according to the various parameter combinations, and recording the execution results of the various parameter combinations, including: successful order creation, insufficient inventory error, invalid address, etc.;

[0115] During the test execution process, all executed code links are monitored and recorded. When it is found that a specific link (exception handling when the product ID does not exist) is not executed, the developer is notified of the existence of the untested link and the possible cause analysis is provided. For example, it may be that the parameter combination does not contain the empty product ID. Parameter adjustment suggestions are intelligently generated. Based on the intelligently generated parameters, the function is tested again to finally confirm that all links are accessed. After the test is completed, a detailed test report is generated, indicating all executed links and problems found for the developer to review and fix.

[0116] In this embodiment, each logical branch of the processOrder function is fully tested through the automated testing strategy, ensuring the stability and reliability of the order processing function. Developers can discover and fix potential defects in a timely manner, thereby improving software quality and user satisfaction.
