Embodiment Construction

[0042] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0043] Such as figure 1 As shown, this embodiment provides a method for automatically generating test cases for a vehicle light controller based on a state machine. All states and trigger events of the vehicle light controller are marked with symbols one by one, so that the system of the vehicle light controller The requirement is abstracted into a finite automatic state machine model. According to this model, the test case of the car light controller is automatically generated by the tool, which is efficient, saves manpower, is not easy to make mistakes, and provides an effective basis for the coverage of statistical test requirements;

[0044] Include the following steps:

[0045] Step...

Abstract

The invention aims to provide a test case automatic generation method for a vehicle lamp controller based on a state machine, which comprises the following steps of: marking all states and trigger events of the vehicle lamp controller one by one by using symbols so as to abstract system requirements of the vehicle lamp controller into a finite automatic state machine model; according to the model,automatically generating a test case of the vehicle lamp controller by a tool; abstracting a state flow chart of the vehicle lamp controller into a state machine model, automatically generating all test cases by a tool, the efficiency is high so that manpower is saved, errors are not likely to happen, and an effective basis is provided for statistics of the coverage rate of test requirements; thedefect that in the prior art, the process is large in workload and tedious is overcome, and careless omission during manual operation is avoided.

Description

technical field [0001] The invention relates to the field of automobile lamps, in particular to a method for automatically generating test cases for a lamp controller based on a state machine. Background technique [0002] As the application of automotive lighting software becomes more and more widespread, the importance of whether the functions actually implemented by the software can meet the requirements defined by customers has become more and more prominent. Therefore, system testing has become an indispensable key link to verify the correctness of software functions. The current system test mainly follows the following steps: [0003] In the first step, testers design test cases according to the system requirements of the light controller to cover as many system functions as possible. Test cases are mainly composed of preconditions, test steps and expected results. [0004] The second step is to build a test environment for automotive lighting products, including DC ...
