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 virtual partition and real-time script technology to perform simulation tests on partition application software of the integrated modular embedded system. The present invention takes partition application configuration information files, module configuration information files and partition application programs as inputs, simulates the operating environment of partition applications on a real hardware platform, and uses virtual partitions to interact with partition applications for real-time incentives And collect the response. At the same time, the real-time script located in the virtual partition can perform fault injection and status monitoring of the partition application. The overall structure of the test system is as figure 2 Shown. figure 1 It is a software architecture diagram 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.

Description

Technical field [0001] The present invention provides a simulation test method for embedded system partition application software, in particular to a simulation test method for integrated modular embedded system partition application software, which is an embedded software simulation test method, It is mainly oriented to the partitioned application software of integrated modular embedded systems. It is related to embedded software testing technology, embedded software scripting technology and software fault injection technology, and belongs to the field of software testing technology. Background technique [0002] In recent years, as the functions of embedded systems have become more and more complex, the software and hardware structure of the system has also continued to change. Embedded system software is transformed from a traditional structure with single function and tightly coupled software and hardware to a modular, multi-level, and open software architecture. among them:...
