[0030] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0031] The following describes the implementation methods of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

It should be noted that, in the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0032] In an embodiment of the present invention, an integrated testing method for an embedded system is provided, in which the test code and the engineering code are completely separated, and the code maintenance is convenient; at the same time, it is convenient for division of labor, and test case development and function development can be carried out simultaneously. The test code writer only needs to care about the external interface of the system and does not need to care about the internal details of the system at all; the entire testing process can be automated, thereby improving the testing efficiency.

[0033] like Figure 3 As shown, the present invention provides an integrated testing method for an embedded system, wherein the embedded system includes a testing system and a system under test, and the method specifically includes:

[0034] The test system establishes a communication connection with the system under test, wherein the test system includes a communication interface module and a use case management module, the system under test includes a communication adapter module and a service management module, and the communication connection between the test system and the system under test is realized based on the connection between the communication adapter module and the communication interface module;

[0035] Furthermore, the communication interface module is used to simulate multiple external interfaces of the system under test, and the communication adaptation module performs interface adaptation based on different external interfaces.

[0036] Specifically, the test system provided in this embodiment communicates with the system under test in a manner supported by both parties. The communication interface module of the test system is used to simulate multiple external interfaces of the system under test. The system under test adapts to the communication interface of the test system through the communication adapter module, thereby establishing a connection with the test system. Figure 1As shown in the figure, the communication interface module of the test system simulates the external interface of the system under test, and sends messages to the system under test through the use case management module to trigger related services; after the system under test processes the services, it sends the results that need to be output externally to the test system. For each external interface, the system under test has a corresponding communication adapter module to send and receive data; at the same time, the business management module completes data decoding and corresponding functions. The system structure diagram of the system under test is shown in the figure. Figure 2 As shown, the communication interface module of the test system is used to realize the underlying communication with the system under test; the test case management module is used to realize the specific test case functions.

[0037] according to Figure 3 As shown, perform the following test steps for each use case:

[0038] Step S1, the use case management module encodes a simulation message according to the interface requirements of the communication adapter module, and sends the simulation information to the communication adapter module;

[0039] Step S2, after receiving the simulation message, the communication adapter module forwards the simulation message to the service management module for processing, and the service management module sends the processing result to the test system after processing;

[0040] Step S3, the use case management module decodes the message according to the interface definition of the communication adapter module, presets the test result, compares the preset test result with the test result in the processing result to see if they are consistent, if they are consistent, the use case is determined to have passed; otherwise, the use case is determined to have failed.

[0041] Furthermore, after executing the above S1, S2, and S3 test steps for all use cases respectively, the execution results of each use case are counted and a test report is generated.

[0042] Furthermore, the user modifies the test system and the system under test according to the test report, and then re-executes the test steps of each of the use cases until all of the use cases are determined to have passed.

[0043] Specifically, if Figure 3 As shown, for a single test case, the test system first generates a simulation message according to the external interface protocol of the system under test and sends it to the system under test; secondly, after receiving the message, the communication adapter module of the system under test forwards it to the business management module for processing, and the business management module sends the processing result to the test system after processing; the test system decodes the message according to the external interface protocol of the system under test, extracts the execution result returned by the test system from the decoded message, and compares the expected result with the result actually returned by the test system. If they are consistent, the case is judged to have passed; if they are inconsistent, the case fails.

[0044] For the integration test of multiple use cases, after the system under test and the test system are started, the test steps S1, S2, and S3 of each use case are executed cyclically; after all use cases are executed, the use case execution results are counted and a test report is generated. Users can determine whether the problem is with the system under test or the test system based on the test report. After correcting the problem, re-test the use case until all use cases are judged to have passed. After starting the system under test and the test system, the entire integration test process can be completed automatically.

[0045] Based on the same inventive concept, an integrated test system for an embedded system is also provided in the embodiments of the present invention, as described in the following embodiments. Since the principle of solving the problem by an integrated test system for an embedded system is similar to that of an integrated test method for an embedded system, the implementation of an integrated test system for an embedded system can refer to the implementation of an integrated test method for an embedded system, and the repetitions are not repeated. As used below, the term "unit" or "module" can be a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware is also possible and conceived.

[0048] The use case testing module 402 is used to perform the following test steps for each use case:

[0049] Step S1, the use case management module encodes a simulation message according to the interface requirements of the communication adapter module, and sends the simulation information to the communication adapter module;

[0050] Step S2, after receiving the simulation message, the communication adapter module forwards the simulation message to the service management module for processing, and the service management module sends the processing result to the test system after processing;

[0051] Step S3, the use case management module decodes the message according to the interface definition of the communication adapter module, presets the test result, compares the preset test result with the test result in the processing result to see if they are consistent, if they are consistent, the use case is determined to have passed; otherwise, the use case is determined to have failed.
