Problems solved by technology

Although each partitioned application can run independently, it lacks cross-linking with other partitions, making it difficult to implement a comprehensive test of the functions of the partitioned application
[0008] For the current test of the partition application program, a test module is usually developed independently at the system internal bus level, and the simulation of other embedded partition functions is realized by simulating the internal bus data, but this method needs to redesign the hardware and software, and the cost is high. Poor versatility, difficult to adopt

Embodiment Construction

[0068] The invention utilizes the virtual partition and real-time script technology to simulate and test the partition application software of the comprehensive modular embedded system. The invention takes the partition application configuration information file, the module configuration information file and the partition application program as input, simulates the running environment of the partition application program on the real hardware platform, and utilizes the virtual partition to perform data interaction with the partition application program, and stimulates the partition application program in real time. and collect responses. Simultaneously, real-time scripts located inside virtual partitions can perform fault injection and status monitoring of partitioned applications. The overall structure of the test system is as follows figure 2 shown. figure 1 It is a diagram of the software architecture of a comprehensive modular embedded system.

Abstract

A simulation testing method for partition application software of an embedded system comprises five steps: step one, building a testing model; step two, generating testing configuration information and a virtual partition code according to the testing model; step three, writing a testing script, and writing a response action for an allocated event occurring during the testing process; step four, performing testing on a partition application to be tested; and step five, collecting and analyzing the testing data. The simulation testing method for the partition application software of the embedded system can be implemented in a development and integration test phase of a partition embedded software applicationand can test or verify the execution sequence, the scheduling performance and the interface communication function of the partition embedded software application. The technical scheme of the simulation testing method for the partition application software of the embedded system comprises the steps of utilizing a calculation and storage unit of a core operating system, simulating the dynamic behaviors of other partition applications on line through a virtual partition mode, and exerting testing actuation to the application to be tested and receiving response. The simulation testing method for the partition application software of the embedded system has a broad application prospect in the technical field of software testing.
