Test method and test system

Abstract

The invention provides a test method and a test system. A testing unit receives testing commands which are sent by an upper computer and include testing content, analyzes the testing commands, and distributes the testing commands to a testing module which corresponds to the testing content of the testing commands. The corresponding testing module outputs testing signals which correspond to the testing content to a detected unit according to the testing commands and feeds testing output commands back to the upper computer. The upper computer sends reading port status commands to the detected unit after the upper computer receives the testing output commands. The detected unit reads port status information according to the reading port status commands after the detected unit receives the reading port status commands and feeds the port status information back to the upper computer. The upper computer produces testing results through comparing output commands with the port status information. The test method and the test system enable testing procedures to be easy compared with the prior art, wherein corresponding testing signal sources are needed to be exchanged according to different controller models in the prior art.

Description

technical field [0001] The present invention relates to the technical field of testing, and more specifically relates to a testing method and system. Background technique [0002] At present, many domestic companies can design and develop ECU (Electronic Control Unit, Electronic Control Unit) controllers by themselves, but there is still a lack of corresponding high-tech testing links in the production process. This is also one of the bottlenecks restricting the development of domestic ECU technology. [0003] The test signal source box is the test equipment for the controller. The existing test signal source box only includes the test unit for each controller that needs to be debugged and tested. In the specific test, it is necessary to replace the corresponding one according to the different controller models. Testing the signal source box will make the testing process cumbersome. Contents of the invention [0004] In view of this, this case proposes a test system, the...
