Embodiment

[0026] For example, for the test of the core module of the car audio, design a test case library, which includes the test of the eject (Eject) function, the specific steps are as follows:

[0027] (1) The test device sends the eject (Eject) command: 0x11; at this time, the device under test will call and execute the function function: void mmi_cdp_eject_disc();

[0028] (2) The monitoring device receives and records the first status information returned by the device under test within 15ms: 0x20 0x01 0x05;

[0029] (3) The monitoring device receives and records the second status message returned by the device under test within 540ms: 0x20 0x01 0x01; according to the definition of the communication protocol, receiving the first message indicates that the playback status of the movement has stopped and the disc is currently being released. Receive the second message indicating that the movement stops playing, and the current disc output has been completed;

Abstract

The invention discloses an embedded system automation module test method on the basis of the data communication monitoring. The method comprises the following steps of: calling a performance function of each functional module inside a vehicle-mounted automobile sound system by an external control module; and monitoring the communication between sub modules inside the vehicle-mounted automobile sound system and the feedback of various state information by the external control module so as to judge whether the performance functions are correctly implemented. Due to the application of the embedded system automation module test method, not only can the interface test work of each functional module inside the vehicle-mounted automobile sound system be automatically completed, a test result is given and a test report is generated, but also a test engineer can keep mind on the design of the test scheme rather than the repeated manual operation. Moreover, various trace log information in the generated test report is helpful for a development engineer to carry out positioning analysis and solve the problems and is helpful for improving the efficiency of software development.

Description

technical field [0001] The invention relates to system automatic testing, in particular to an embedded system automatic module testing method based on data communication monitoring. Background technique [0002] Generally, in the automotive electronics industry, the functional definition of the car audio system has basically taken shape. However, the test of the car audio system still mainly relies on manual testing, and repetitive testing takes up a lot of resources. Contents of the invention [0003] For the problems existing in the prior art, the purpose of this invention is to provide a kind of embedded system automatic module testing method based on data communication monitoring, the method calls the function function of each functional module inside the car audio system by the external control module; The external control module monitors the communication between various sub-modules in the car audio system and the feedback of various status information to judge whet...
