[0034] 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.

[0035] It should be noted that the collection, collection, updating, analysis, processing, use, transmission, storage and other aspects of user personal information involved in the technical solution of the present invention are in compliance with the provisions of relevant laws and regulations, are used for legitimate purposes, and do not violate public order and good morals. Necessary measures are taken for user personal information to prevent illegal access to user personal information data and maintain the security of user personal information, network security and national security.

[0036] The current testing plan is to construct test cases based on business scenarios, build a test environment through test cases, and use the test environment for testing. However, the core application business scenarios are complex, and testers are unfamiliar with older businesses. It is difficult for testers to construct test scenarios, resulting in incomplete automated test cases for existing business logic codes and low code coverage. The testing process before going online requires a lot of manual verification.

[0037] The present invention is based on obtaining test requests through real-time or offline diversion of online requests, relying on comparing the test results of the pre-release environment with the test results of the test environment, filtering and screening the real business scenarios of the code not covered by the test environment, so as to construct automated test cases, improve the coverage of core application codes, and thus improve the stability and high availability of the business system.

[0038] Figure 1 It is a schematic diagram of main steps of a testing method according to an embodiment of the present invention.

[0039] like Figure 1 As shown, the testing method of one embodiment of the present invention mainly includes the following steps S101 to S104.

[0040] Step S101: obtain an online request from a production environment, and copy the online request to generate a test request.

[0041] In one embodiment, obtaining online requests from a production environment and duplicating the online requests to generate test requests may include: using a proxy recording device to generate test requests by recording requests in the production environment in real time.

[0042] Specifically, a proxy recording device can be used to record all requests in the production environment within a preset time period to obtain a test request, or to directly forward the online request in the production environment as a test request to the pre-release environment and the test environment. Among them, the proxy recording device may include a recorder Recorder, a buffer Buffer, and a reporter Reporter. The recorder Recorder can intercept online requests in the production environment based on the responsibility chain model. In the responsibility chain model, multiple processors can process the same online request in sequence. An online request is first processed by processor A, and then the online request is passed to processor B, and so on, forming a chain. Each processor in the chain assumes its own processing responsibility. For example, processor A can be used to record online requests, and processor B can be used to process online requests in the production environment; the buffer Buffer can provide a temporary storage function for requests, which is implemented by a small bounded queue internally; the reporter Reporter can asynchronously report the requests in the buffer area to the receiver, thereby obtaining real-time recorded requests.

[0043] Step S102: According to the test request, the pre-release environment and the test environment are tested respectively to obtain the pre-release environment test result and the test environment test result.

[0044] In one embodiment, the pre-launch environment may be generated in the following manner: according to the production environment, an offline environment corresponding to the production environment is constructed, and the offline environment is used as the pre-launch environment.

[0045] Specifically, according to the production environment, an offline environment can be constructed by duplicating the production environment, or when there are multiple production environment backups, one production environment backup can be selected for offline processing to obtain an offline environment.

[0046] In one embodiment, according to the test request, testing is performed through the pre-release environment and the test environment respectively to obtain the pre-release environment test results and the test environment test results, which may include: according to the test request, performing code coverage testing on the pre-release environment through a code coverage tool, and using the code coverage test results of the pre-release environment as the pre-release environment test results; according to the test request, performing code coverage testing on the test environment through a code coverage tool, and using the code coverage test results of the test environment as the test environment test results.

[0047] Code coverage testing refers to the percentage of code covered by test cases through manual testing and automated testing using a test automation framework. Code coverage tools can be Coverage.py (a code coverage tool for Python), Serenity BDD (a code coverage tool that supports Java and Groovy programming languages), JaCoCo (a code coverage tool for Java), JCov (a test framework agnostic code coverage tool), etc. Before code coverage testing, the code coverage tool is deployed to the environment to be tested in an instrumented mode.

[0048] In another embodiment, the test environment test result may be obtained by pre-executing an existing test case in the test environment, the existing test case may be an automated test case, and the pre-launch environment test result is obtained by executing a test request in the pre-launch environment.

[0049] In one embodiment, before testing through the pre-release environment and the test environment respectively, the test requests can be screened according to the business scenario, and the test can be performed through the pre-release environment and the test environment according to the screened test requests, so as to optimize the test environment according to the business scenario and improve the efficiency of the test environment optimization.

[0050] Step S103: Compare the pre-release environment test results with the test environment test results to obtain uncovered code.

[0051] In one embodiment, comparing the pre-launch environment test results with the test environment test results to obtain uncovered code may include: comparing the pre-launch environment test results with the test environment test results; and treating the code that is covered in the pre-launch environment test results and not covered in the test environment test results as uncovered code.

[0052] Specifically, the pre-release environment test results and the test environment test results can be compared through the diff (same-layer comparison) algorithm to determine the code that is covered in the pre-release environment test results but not covered in the test environment test results, and use it as uncovered code. Therefore, based on the uncovered code, it is possible to determine the test cases that need to be supplemented in the test environment compared with the online production environment.

[0053] Step S104: construct test cases according to the uncovered code to optimize the test environment, and perform testing through the optimized test environment.

[0054] In one embodiment, constructing test cases according to uncovered code to optimize the test environment may include: constructing corresponding test cases according to the uncovered code, and adding the test cases to the test environment to optimize the test environment.

[0055] Specifically, the uncovered code can be screened based on the business scenario to obtain the uncovered code corresponding to the business scenario, construct test cases according to the uncovered code corresponding to the business scenario, and add the constructed test cases to the test environment.

[0056] In one embodiment, after constructing test cases based on uncovered code to optimize the test environment, it can also include: based on the test request, re-testing the optimized test environment to generate test results for the optimized test environment; and verifying the test cases based on the test results of the optimized test environment and the uncovered code.

[0057] Specifically, it is determined whether the uncovered code is covered in the test results of the optimized test environment. If the uncovered code is covered in the test results of the optimized test environment, the test case verification passes, indicating that the test environment optimization is successful.

[0058] Figure 2 It is a flowchart of a testing method according to an embodiment of the present invention.

[0059] like Figure 2 As shown, in one embodiment, a corresponding offline environment is constructed according to the production environment as a pre-release environment, online requests are obtained from the production environment, the online requests are copied, and test requests are generated. The test requests are used to perform tests through the pre-release environment and the test environment, and the pre-release environment test results and the test environment test results are obtained. The uncovered code is obtained, and test cases are constructed according to the uncovered code to optimize the test environment.

[0060] The embodiment of the present invention forwards real online requests to a pre-release environment and a test environment, relies on coverage results for comparison, improves automated test cases, increases the coverage of core applications, and optimizes the test environment.

[0063] The test request generation module 301 is used to obtain online requests from the production environment, and copy the online requests to generate test requests.

[0064] The test result generating module 302 is used to perform tests in the pre-release environment and the test environment respectively according to the test request, and obtain the pre-release environment test result and the test environment test result.

[0071] In one embodiment, the test environment optimization module 304 is specifically used to construct corresponding test cases according to the uncovered code, and add the test cases to the test environment to optimize the test environment.

[0072] In one embodiment, the test environment optimization module 304 is specifically used to: retest the optimized test environment based on the test request to generate the test results of the optimized test environment; and verify the test cases according to the test results of the optimized test environment and the uncovered code.

[0073] In addition, the specific implementation content of the testing device in the embodiment of the present invention has been described in detail in the above testing method, so the repeated content will not be described again here.
