Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Hereinafter, the method and apparatus for testing a data interface provided in the embodiments of the present application will be described and explained in detail with several specific embodiments.
In an embodiment, a method for testing a data interface is provided, and the method is applied to a server and used for realizing the test of the data interface. The server can be an independent server or a server cluster formed by a plurality of servers, and can also be a cloud server for providing basic cloud computing services such as cloud service, a cloud database, cloud computing, cloud functions, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN (content delivery network) and large data and artificial intelligence sampling point equipment.
As shown in fig. 1, the method for testing a data interface provided in this embodiment includes:
102, determining a boundary value of each input parameter according to an input field of each input parameter specified in the interface document;
103, determining a test value of the input parameter according to the boundary value of the input parameter, so as to generate a test case for testing the data interface according to the test value of at least one input parameter, and acquiring a test execution result;
wherein the input field is used for limiting the value interval of the input parameter;
the boundary value is at least one of a maximum value and a minimum value in the input domain.
The boundary value of the input parameter is rapidly determined through the interface document of the data interface, the test value of the input parameter is determined according to the boundary value by utilizing the characteristic that a large number of errors often occur on the boundary of an input or output range, and a test case is generated according to the test value to test the data interface, so that the test value on the boundary can be rapidly obtained to test the data interface, all parameter values are not required to be exhausted during testing, the time cost of testing is greatly reduced, and the testing efficiency of the data interface is improved.
In one embodiment, the interface document of the data interface may be a document having a standard message format. For example, a document in JSON (JSON Object Notation) format. The interface document records the parameter types of the input parameters which can be received by the data interface and the input fields of the input parameters. For example, an interface document of a data interface a records types of input parameters a, b and c which can be received by the data interface a, input fields of the input parameters are respectively a >25, b is a positive integer, and 0-c-s-100. The interface document can be stored in a database of the terminal device where the data interface is located, and the server can access the data interface to obtain the interface document of the data interface from the database of the terminal device.
After the server obtains the interface document, the server may parse the interface document to obtain, from the interface document, input parameter types that may be received by the data interface a and input fields of the input parameters, and then determine boundary values of the input parameters according to the input fields of the input parameters specified in the interface document. Illustratively, the input parameters recorded in the interface document include a, b, and c, the input fields of the respective input parameters are a >25, b is a positive integer, and 0-cloth c-cloth 100, in which case it is determined that the boundary value of the input parameter a is 25, the boundary value of b is 1, and the boundary value of c is 0 and 100. It will be appreciated that the number of boundary values for an input parameter may be determined based on the number of endpoints for the input field for that input parameter. If the input field of the input parameter a is a >25, the end point is 25, that is, the number of the end points of the input field is 1; if the input fields of the input parameters a are 25-a-straw 100, the end points thereof are 25 and 100, and the number of the end points of the input fields is 2.
After the boundary value of each input parameter is determined, the processing test of the test interface on a single input parameter or a plurality of input parameters can be carried out. For the processing test of a single input parameter, the boundary value of the input parameter is used as a test value according to the input parameter to be tested of the test interface, the normal values of the other input parameters are selected, and then a test case is generated according to the values of the input parameters to test the data interface. Illustratively, the parameter types of the input parameters specified in the interface document are a, b and c, the input fields of the input parameters are a >25, b is a positive integer, and 0-n-c-n-100, respectively, and currently only the processing condition of the interface on the input parameters a needs to be tested, at this time, the value of a may be 25, that is, the test value of the input parameter a is 25, the input parameter b randomly takes a positive integer, and the input parameter c randomly takes a value from 0 to 100. After the test value of the input parameter a is obtained, the test value 25 of the input parameter a, and the values selected by the input parameter b and the input parameter c can be input to the data interface as test cases for testing.
Similarly, when only the test interface is needed to process the input parameter b, the value of b may be 1, that is, the test value of the input parameter b is 1, the input parameter a randomly takes a value larger than 25, and the input parameter c randomly takes a value from 0 to 100.
Similarly, for the processing test of a plurality of input parameters, the boundary value of each input parameter to be tested by the test interface is used as the test value, and the normal value is selected for the rest of the input parameters to generate the test case.
In addition to the boundary value, the parameter values around the boundary value may also affect the test result, so in order to further improve the accuracy of the test result, in an embodiment, as shown in fig. 2, determining the test value of the input parameter according to the boundary value of the input parameter includes:
For example, if the input parameter is b, the boundary value is 1, and the corresponding input field is b is a positive integer, a parameter value smaller than the boundary value, such as a parameter value of 0 or-1, may be selected as the first target value. Meanwhile, a parameter value larger than the boundary value, such as a parameter value of 2 or 3, may be selected as the second target value.
After the first target value and the second target value are determined, the boundary value, the first target value and the second target value may be determined as the test values of the input parameters.
Illustratively, the parameter types of the input parameters specified in the interface document are a, b and c, the input fields of the input parameters are a >25, b is a positive integer, and 0-c-100, respectively, and the processing condition of the interface to the input parameter a currently needs to be tested, at this time, 24, 25 and 26 can be taken as the test value of the input parameter a, meanwhile, the input parameter b and the input parameter c are within the normal required range, such as the random positive integer of the input parameter b, and the input parameter c is within a value from 0 to 100. And then, combining the test value of any input parameter a, and the input parameter b and the input parameter c which are randomly obtained to form a test case.
The first target value outside the input domain and the second target value inside the input domain are determined through the boundary value of the input parameter, and the boundary value, the first target value and the second target value are determined as the test value of the input parameter, so that the boundary can be more comprehensively utilized to test the data interface through the boundary value and the parameter values inside and outside the input domain, and the accuracy of the test result is further improved.
To ensure that the data interface can be tested with a boundary, in an embodiment the first target value and the second target value are adjacent to the boundary value, i.e. parameter values just above and just below the boundary are selected to form the test value with the boundary value. If the input field of the input parameter a is a positive integer from 0 to 1000, the boundary values of the input parameter are 0 and 1000, the first target values are-1 and 1000, and the second target values are 1 and 999. Thus, a test value of-1, 0,1, 999, 1000, 1001 for input parameter a can be determined.
Because the first target value and the second target value are adjacent to the boundary value, the obtained test value can better cover the boundary of the input domain, so that the boundary can be more comprehensively utilized to test the data interface, and the accuracy of the test result is improved.
In order to better improve the accuracy of the test result considering that some errors may also occur within the input range, in an embodiment, as shown in fig. 3, the method further includes:
In an embodiment, after the boundary value, the first objective value and the second objective value are determined as the test values of the input parameter, the preset value interval may be further determined according to a neighborhood range near the input domain. The neighborhood range can be set according to actual conditions. And if a plurality of boundary values exist, sequentially acquiring a plurality of third target values from the input domain according to a preset value interval by taking the minimum boundary value as a starting point. Illustratively, the input field is a positive integer of 0 to 1000, and the field range is 0 to 100, at this time, the maximum value of the field range is determined as the preset value interval, and values are taken every 100 starting from the boundary value 0, so as to obtain a plurality of third target values 99, 199, 299, and the like, respectively. And then, adding the acquired plurality of third target values into the test value of the input parameter.
And acquiring a plurality of third target values in the input domain from the boundary value by presetting the value interval, so that the acquired test values are more comprehensive, and the accuracy of the test result can be further improved.
It is considered that when the third target value is obtained to add the test value, the test efficiency is affected due to a large number of test values, and only a part of types of errors of the input parameters occur inside the input field. Therefore, in an embodiment, starting from the boundary value, a plurality of third target values are obtained in the input domain according to a preset value interval, including:
determining the parameter type of the input parameter as a preset parameter type, and acquiring a plurality of third target values in the input domain according to a preset value interval from the boundary value;
the preset parameter type is a parameter type in which the probability of an error occurring inside the input domain is greater than a preset probability when a data interface test is performed.
In an embodiment, the server stores a plurality of preset parameter types required to obtain the third target value in advance. After the boundary value, the first target value and the second target value are determined as the test values of the input parameters, the parameter types of the input parameters can be obtained, and then the parameter types are matched with all preset parameter types. If a preset parameter type which is the same as the parameter type exists, starting from the boundary value, and acquiring a plurality of third target values in the input domain according to a preset value interval; otherwise, the extraction of the third target value need not be performed. When the data interface test is performed through a large number of tests, the probability that an error of a certain parameter type occurs in the input domain is larger than the preset probability, and the parameter type is determined to be the preset parameter type. The preset probability can be determined according to actual conditions.
Illustratively, the preset parameter types pre-stored in the server are an input parameter a and an input parameter b, and if the parameter type of the input parameter is a, a plurality of third target values are obtained from the boundary value and in an early input domain according to a preset value interval; if the parameter type of the input parameter is c, the extraction of the third target value is not required.
After the parameter type of the input parameter is determined to be the preset parameter type, a plurality of third target values are obtained in the input domain from the boundary value according to the preset value interval, so that the third target values are extracted only for the parameter types with the probability of the error occurring in the input domain being greater than the preset probability when the data interface test is performed, and the test efficiency is prevented from being influenced by more test values of the input parameter without the need of extracting the third target values.
After the test values of the input parameters are obtained, the test case can be generated through the test values, and therefore the data interface is tested. In order to further improve the testing efficiency, in an embodiment, as shown in fig. 4, generating a test case according to a test value of at least one of the input parameters to perform a test on the data interface, and obtaining a test execution result includes:
step 402, generating a test case according to the test values of any two input parameters of which the correlation coefficients reach the preset values, testing the data interface, and obtaining a test execution result.
In one embodiment, after the input parameters are obtained from the interface document, the relevance of the input parameters in the interface document can be subjected to combined analysis. Specifically, by a correlation coefficient algorithm:
and determining a test value of the input parameter X and a test value correlation coefficient of the input parameter Y. Where Cov (X, Y) is the covariance of all the test values of the input parameter X and all the test values of the input parameter Y, V (X) is the variance of all the test values of the input parameter X, and V (Y) is the variance of all the test values of the input parameter Y.
After the correlation coefficient between the test values of the two input parameters is obtained, if the correlation coefficient reaches a preset value, the test values of the two input parameters are strongly boundary correlated, and a test case is generated according to the test values of the two input parameters to test the data interface, so that comprehensive and proper coverage is achieved, redundant execution does not exist, and the test coverage condition after the combination of a plurality of input parameters is not omitted.
In an embodiment, after obtaining the test execution result, the method further includes:
comparing the test execution result with a preset result to determine a test result;
and determining the preset result according to the test value of the test case.
Illustratively, the parameter types of the input parameters specified in the interface document are a, b and c types, the input field of the input parameter a is a >25, and if the test value of the input parameter a in the test case is 26, the preset result is a test error. After the test execution result is obtained, if the test execution result is the same as the preset result, the test execution result is a test error, and the test result is determined to be accurate; otherwise, determining that the test result is a test execution result error.
