Engine control software testing method

Abstract

The invention relates to a software testing method, in particular to an engine control software testing method, and solves the technical problem that the data throughput capacity of an RS-232 serial port communication mode cannot meet the rapid data access requirement due to the fact that the baud rate cannot be increased under the condition that the serial port communication mode is ensured by an existing engine software testing method. Comprising the following steps of: writing a keyword in a Workitem.log file, supplying power after communication between test equipment and a product is established, executing a keyword instruction at the moment, running content indicated by the keyword, finishing checking whether the Wkresut.log file exists or not, and writing 'Done!' if the Wkresut.log file exists, and the like. Different functions are operated according to actual conditions, each function corresponds to a respective keyword, mode switching and data packaging downloading are carried out on instructions in a product, the number of handshake times between communication and the product is reduced, the whole access and transmission efficiency is improved by properly reducing data traffic on serial port communication, and the service life of the product is prolonged. Therefore, the purpose of improving the communication transmission efficiency of the RS-232 serial port is achieved.

Description

technical field [0001] The invention relates to a software testing method, in particular to an engine control software testing method, which is an automatic and intelligent testing method and a method for improving communication transmission efficiency between RS-232 serial port protocol and virtual DOS system. Background technique [0002] Virtual Machine (Virtual Machine) technology is a kind of virtualization technology, which can provide the functions of a physical computer by simulating a complete computer system with complete hardware system functions and running in a completely isolated environment through software. Virtual machines can be divided into system virtual machines and program virtual machines according to their application and relationship to the direct machine. Using a virtual machine, the operating system of traditional test equipment can be simulated by software, and a virtual environment independent of the actual hardware can be virtualized for custome...
