Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

In the related art, a test case is a case of a set of test inputs, execution conditions, and expected results written for a particular target to verify whether a particular software requirement is met. The interface may be an application program interface, and may be a predefined interface, such as a function interface, a HyperText Transfer Protocol (HTTP) interface, and the like.

In the related art, the interface test is a test for testing interfaces between components of a system, and is mainly used for testing interfaces between the test system and other external systems and testing interfaces between sub-modules in the system. The interface test mainly checks the correctness of interface parameter transmission, the correctness of interface function realization, the correctness of output results, and the integrity and the reasonableness of fault-tolerant processing of various abnormal conditions. Errors (bugs) in computer programs can be discovered in advance through interface testing, which has the advantage of being cost-effective as the interface testing can be automated and is continuously integrated.

In the interface test process, a test case of the interface needs to be compiled, and the test case is executed to complete the test of the interface. The design of the test case of the interface has similarities with the design of the unit test case, and basic test methods such as a boundary value method and an equivalence method need to be adopted. The starting point of the test case for designing the interface is to verify the consistency of the function and performance index realized by the interface and the interface description document.

At present, the test case compiling of the interface is mainly realized in a manual mode, and the implementation process is as follows: firstly, an interface description document is needed to be referred to, the name of input parameters, the numerical type, the value range, whether the input parameters need to be filled and the like of each interface are determined, wherein the combination of the input parameters needs to follow the design methods of test cases such as an equivalence class method, a boundary value method and the like, all typical input parameter combinations are covered by the minimum number of the test cases, each test case covers different test points, and each test case can not be replaced. Secondly, according to the interface description document, all possible returned output results of each interface are determined, corresponding expected results are added into the response assertions of the test cases respectively, and whether the interface functions are correct or not is judged by judging the consistency of the actual output results of the interfaces and the expected results of the interface test cases. And finally, adding an expected result of the response time into the response assertion of the test case, and judging whether the performance of the interface meets the requirement by judging whether the actual response time of the interface reaches the expected result.

When the input parameters and the output results of a certain interface are too many, in order to ensure the coverage rate of the test, various tests need to be performed on each input parameter, and corresponding input parameters need to be constructed for the possibility of outputting the results, so as to generate a test case for verifying whether the actual output results of the interface meet the expected results. The more complex the interface is, the more test points are, the more the number of test cases written for the interface is, in a conventional software test project, the more the test cases of one interface may be, the time consumed by a mode of manually writing the test cases cannot meet the test requirements of a fast and efficient software project, and in the process of manually writing the test cases, problems that the input parameters are wrongly written or the test cases cannot pass due to other operations may exist, and the time is wasted when the problems are checked.

In order to solve the above problem, an embodiment of the present invention provides a method for generating a test case of an interface, and fig. 1a is a flowchart of the method for generating a test case of an interface, where the method may be executed by a device for generating a test case of an interface, the device may be implemented by software and/or hardware, the device may be configured in an electronic device, and the method may be applied in a scenario of interface testing.

The reverse test case can be understood as inputting wrong input parameters, and whether the interface feeds back corresponding output parameters is verified. Under the condition that the test case is a forward test case, the name of the test case can be generated based on the interface name, the interface number and the type information of the test case, so that testers can conveniently know and distinguish the information of the test case.

For example, the format of the input parameters may be { "mandatory input parameter 1": a, "must fill input parameter 2": b, "must fill in parameter 3": c. Optionally, test data may be generated based on "whether the input parameter is a must-fill input parameter, a value range of the input parameter, and a value type", so that the test data is assigned to the corresponding input parameter, and an input parameter value of the test case is generated.

If the first input parameter is the necessary input parameter and the sequence number of the first input parameter is less than or equal to the total number of the necessary input parameters, generating the name of the test case; otherwise, the flow ends.

For example, if the value range of the third input parameter is [1,100], the value type is int, and the generated third test data may be 120, where 120 is not in the value range of the third input parameter but conforms to the value type. For another example, if the value range of the third input parameter is [5,10], if the value type is str, then the length of the representation character string is [5,10], then a random generation function may be called to generate a character string whose length is not within the range of [5,10], for example, third test data abc may be generated, and the value range of abc exceeds the value range of the third input parameter and conforms to the value type of the third input parameter.

In an embodiment of the present invention, each interface has a plurality of corresponding input parameters. In addition to the third input parameter, the input parameters of the interface are fourth input parameters, wherein the number of the fourth input parameters including the parameter may be at least one. The generation of the fourth test data is the same as the method of the first test data in the above embodiment, and will not be described again.

S480: and if the fourth input parameter is a mandatory input parameter, assigning the fourth input parameter to the fourth test data according to the input format to generate a fourth input parameter value of the test case.

In the embodiment of the present invention, a method for generating the fourth input parameter value of the test case is the same as the method for generating the input parameter value described in S260 in the foregoing embodiment, and a description thereof will not be repeated.

S490: generating an expected result of the test case based on the response time and the output parameters in the necessary description information; and the encoding type in the output parameter corresponding to the third input parameter in the expected result is invalid.

In the embodiment of the invention, the value range of the third test data is taken out, the third test data is assigned to the third input parameter, the third input parameter value is an invalid parameter value, the code in the output parameter corresponding to the third input parameter in the expected result is 1002, and the characterization parameter is invalid, so that the input parameter value of the test case is corresponding to the expected result, a correct test case is generated, and the interface is correctly tested.

Therefore, the third input parameter value of the test case is obtained by determining the third test data which exceeds the value range and accords with the value type, assigning the test data to the third input parameter, namely, assigning the third input parameter as an invalid parameter value to obtain the third input parameter value of the test case, and the generated test case can carry out validity verification on the input parameter which belongs to the necessary input parameter by taking the coding type in the output parameter corresponding to the third input parameter in the expected result as the parameter invalid, so that the interface can be comprehensively and correctly tested.
