Abstract

The invention relates to the field of automatic testing of automobile embedded software, in particular to a full-automatic test system for automobile electronic equipment. The test system comprises atest platform; the test platform comprises a hardware system, a lower computer detection control software system and an upper computer configuration software system; the hardware system comprises a communication module, a signal module and a programmable power supply module. Compared with the prior art, the test system can be freely matched with test system hardware, and test cases can be automatically generated through simple configuration to conduct white-box testing and black-box testing on embedded software; all signals and results can be fed back in the testing process, and the problems that when automobile embedded software is tested previously, only manual black-box testing can be conducted, and a large number of repetitive tests can not be conveniently conducted are solved.

Description

technical field [0001] The invention relates to the field of automotive embedded software testing, in particular to the field of automated testing in which white boxes and black boxes of automotive embedded software are combined. Background technique [0002] At present, most of the embedded software tests of automotive electronics are black-box tests performed manually or through the labview automatic test platform. Manual testing is time-consuming, labor-intensive, and has high labor costs and low efficiency. The labview automatic test platform is mainly used in product testing, and the test support for software is not good, and different labview automatic test platforms are required for testing different software, the overall price is expensive, and only black box testing can be performed. In the field of automotive electronics, safety is a very important factor, so white-box testing is very necessary, but the existing testing schemes cannot perform white-box testing of a...
