Embedded software testing auxiliary system

Abstract

The invention provides an embedded software testing auxiliary system, and aims at providing a software testing auxiliary system which can improve the efficiency of building a testing environment, lower the operation difficulty and improve the usability. According to the technical scheme, an upper computer constructs a testing crosslinking environment of tested equipment and testing equipment, describes bus attributes, an interface control document ICD, testing case preconditions and testing steps, forms control law data according to the preconditions and the testing steps to dispatch testing data, sends, judges and receives the data, and conducts reverse analysis on the received data according to an ICD format; a lower computer cooperates with the upper computer to send the data through adetailed bus, then the data is received, testing cases and design constructed by data simulation and receiving-sending procedure control are automatically executed, and simulation of embedded softwareperipheral equipment and monitoring and detecting of the interaction process of peripheral equipment data are achieved. According to the embedded software testing auxiliary system, the testing casesof controlling a construction testing scene are executed based on the data receiving-sending procedure, and the time for developing a simulation system is shortened.

Description

technical field [0001] The invention relates to an embedded software which is widely used in the fields of aviation, aerospace, automobile, communication and home appliances, and is mainly used for MIL-STD-1553B bus, Ethernet, RS232 / 422 / 485 bus, CAN bus and ARNIC429 bus communication Test assist system. Background technique [0002] With the advancement of computer hardware technology, the integration of components has also greatly increased, which has greatly improved the hardware performance of embedded systems; driven by Moore's Law, embedded systems have realized more and more functions The more complex, therefore, the complexity and scale of embedded software are increasing day by day, accounting for a higher proportion in the system, and playing an increasingly important role, and its quality plays a decisive role in the final quality of the entire embedded system . Without strict and effective testing, the potentially dangerous code is delivered to users, which ofte...

AI Technical Summary

Problems solved by technology

[0003] 1. Almost all the system external devices involved in the embedded software are dedicated;

[0004] 2. Embedded software may be difficult to detect and observe during the test process due to lack of usual peripheral equipment;

[0006] 4. The existing hardware-in-the-loop simulation system lacks the ability of test case design and test case automation execution

For the third question, most hardware-in-the-loop simulation test systems lack the ability to simulate the bus data interaction process, or implement secondary development, which brings a lot of inconvenience to the use
