Abstract

An embodiment of the invention provides a method and device for generating a signal forwarding test case and a test system. The method comprises the following steps: acquiring a forwarding signal listfor recording a first to-be-forwarded signal group to be forwarded by a target controller and a DBC (Database Computer) file of each CAN (Controller Area Network) domain connected with the target controller; determining a target forwarding signal group according to each DBC file and the forwarding signal list, and generating a signal address list; performing environment model analysis according to the signal address list, determining a route of each target forwarding signal group in an environment model, and generating a case signal list; and generating a test case according to the case signal list. According to the method provided by the embodiment of the invention, writing of the test case applied to the target controller can be realized by only artificially determining target signal groups having no obvious rules, so that complicated work of manually writing the test case is avoided, and the writing speed and the accuracy of the test case are improved; and therefore, the test period is shortened.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a method, device and testing system for generating signal forwarding test cases. Background technique [0002] Controllers (such as vehicle controllers) connected to multiple CAN (Controller Area Network) domains on a car often need to forward some specific CAN signals from one domain to another. Before and after the signal is forwarded, its attributes remain the same, and there is no complicated logic. However, if there are many forwarded signals, the traditional manual writing of test cases requires a large workload and is prone to errors, and the forwarded signals cannot be stored in each DBC (data base CAN, Data Base Controller Area Network) file when writing test cases. The consistency in the CAN network information description file is checked, and the problem can only be found when the test is completed, which makes the test workload larger and consumes a longer time, prol...
