The test method in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

Referring to fig. 1, a schematic diagram of a network device according to an embodiment of the present application is shown.

As shown in FIG. 1, in a first network device, there are 5 parts including a task pool, a label generator, a test case set, an environment instantiation, and a result analyzer. The function of each part is explained in more detail below. The overall application environment in the application includes a network system, where the network system includes a first network device for deploying an overall test method, a device under test for testing, and auxiliary devices for providing some auxiliary support for a test process, such as providing traffic, data packets, and the like.

Fig. 2 shows a flow chart of a test method according to an embodiment of the present application, including:

step 201: acquiring target file information corresponding to a target test task, and determining a target test tag corresponding to the target file information based on a first mapping relation between preset file information and the test tag.

Specifically, when a developer submits a new code to be tested, the first network device automatically creates a test task and adds the test task to the task pool.

As an optional implementation manner, determining the target test tag corresponding to the target file information based on the first mapping relation between the preset file information and the test tag includes: determining a target hierarchical subdirectory from at least one hierarchical subdirectory contained in the target file information; wherein each of the at least one hierarchical subdirectory includes file information therein; and determining a target test tag corresponding to the file information in the target level subdirectory based on the first mapping relation.

Specifically, the monitoring process sequentially acquires target file information corresponding to a target test task from the task pool, where the target test task corresponds to at least one target file information, the target file information includes directory information where a new code submitted by a developer is located, for example, referring to fig. 3, the target test task includes 6 target file information, the 6 target file information is respectively set in different directory information, a directory a, a directory B, and a directory C may be defined as a first-level subdirectory, and a directory a, a directory B, and a directory C may be defined as a second-level subdirectory.

The first mapping relation is a corresponding relation between preset file information and a test label, the test label is used for identifying the corresponding file information, and the test label corresponding to the target file information can be determined through the first mapping relation. It should be noted that, the tag generator receives the target file information from the task pool, and generates the corresponding target test tag through the directory where the target file information is located.

As an alternative embodiment, determining the target hierarchical subdirectory from at least one hierarchical subdirectory contained in the target file information includes: for each hierarchical subdirectory of the at least one hierarchical subdirectory, determining the hierarchical subdirectory as a target hierarchical subdirectory when the ratio of the number of second file information in the hierarchical subdirectory to the total number of file information contained in the hierarchical subdirectory is greater than or equal to a set threshold; the file information contained in the hierarchical subdirectory comprises first file information belonging to a new addition category and second file information not belonging to the new addition category.

As an alternative embodiment, the threshold is sixty percent, and it should be noted that this threshold may be adjusted according to specific test requirements.

Specifically, referring to FIG. 3, suppose that the target test task in a system modifies the code for a developer by modifying directory A/File 1, modifying directory A/directory a/File 3, modifying directory B/directory a/File 4, and adding directory C/directory C/File 7. Since the proportion of the total number of modified files to the total number of files (6 files) is 50% (because file 7 is newly added and excluded), and is not more than 60% (threshold is set), the hierarchical subdirectory where each file is located is recursively judged. According to the above judgment condition, the file 1 returns to the tag a, the file 3 returns to the tag a (because the total number of files modified by the whole directory a is greater than 60% of the total number of files in the directory a under the directory a, the file 4 returns to the directory a instead of the directory a/a), the file 4 returns to the tag B/a (because the total number of files modified by the whole directory B under the directory B is less than 60% of the total number of files in the directory B, the recursive sub-directory B/a is continued, and thus the sub-directory B/a is returned), and the file 7 carries information (C/file 7) to inform the tester to supplement the functional test case according to the directory information. The label generator outputs the label of the task as (A, B/a), namely, the code modifies all files of the directory A to be tested and the files of the subdirectory a of the directory B.

Step 202: and determining a target test case corresponding to the target test tag based on a second mapping relation between the preset test tag and the test case.

Specifically, the second mapping relationship is a correspondence relationship between a preset test tag and a test case, and is used for associating the target test tag with the target test case, the directory structure of the test case set has a correspondence relationship with the code directory of the system to be tested, the code directory of the system to be tested corresponds to a certain function, meanwhile, the directory name corresponds to the test case of each function in the test case set, that is, the generated target test tag is transmitted to the test case set, and the monitoring process automatically matches the target test case according to the transmitted target test tag, so as to complete the association of the case. According to the test cases corresponding to the test labels, automatic selection of the test cases according to the test labels is achieved, and meanwhile the label generator can accurately correspond to the test cases.

Step 203: under a test environment, testing the target test task by using the target test case; the test environment is obtained by initializing the tested network equipment and the auxiliary test equipment corresponding to the target test task by utilizing the target mirror corresponding to the target test task.

Specifically, this step 203 is executed in the above-mentioned environment instantiation device, after the target test tag is generated, the code corresponding to the test task submitted at this time is packaged into an image or upgrade package, the environment instantiation device uses the image or upgrade package to initialize a test environment, the test environment includes a device to be tested and an auxiliary device in the network system, and after the test environment is ready, the test is started by executing the target test case matched in step 202.

Step 204: determining failure file information corresponding to the failure test case, and feeding back the failure file information; the failed test case refers to a test case in which the test result in the target test case is failed.

Specifically, the result analyzer is used to analyze the test result in step 204 and feed back the test result to the developer. If the test fails, the failure file information corresponding to the failed test case is fed back to the developer, so that the developer can know the failure file information in the target test task, and can be modified and adjusted in a targeted manner.

As an optional implementation manner, determining the failure file information corresponding to the failure test case includes: based on the second mapping relation, determining a failure test label corresponding to the failure test case; and determining failure file information corresponding to the failure test label based on the first mapping relation.

Specifically, based on the second mapping relation established in advance, the failure test label corresponding to the failure test case can be determined, after the failure test label is obtained, based on the first mapping relation established in advance, the failure file information corresponding to the failure test label can be determined, namely, the failure file information corresponding to the failure test case is accurately positioned after the target test task is tested, and a developer only needs to modify the failure file information without modifying all target file information corresponding to the whole target test task.

The method adopts the full-automatic test and test case selection mode, and simultaneously adopts the label generator, so that the modification of codes can be automatically identified, the test case can be automatically selected, the full-automatic process of development, production, test and feedback is completed, the time for receiving the test and the probability of test failure caused by error code submission in the development process are greatly reduced, and the process of developing self-test and upgrading package production is simplified. Meanwhile, the corresponding modification points can be tested in a targeted manner, the testing process is simplified, the overall testing efficiency is improved, and the problems caused by modification of codes can be exposed as soon as possible. The automatic test case matching technology is used, so that test case selection and test execution are invisible to users, and the threshold used by the automatic test system is reduced, namely, all users are faced in a black box mode. Besides the developer, other non-code submitters can also select test cases to execute verification tests only according to the built-in function tags.
