Problems solved by technology

However, due to the different CPUs and external interfaces used by different products, this test method requires different real system equipment, simulation test equipment, test tools, and test platforms for different systems under test, which lacks versatility.
System software testing on a real target machine system needs to work with other systems in the real environment of the system under test, and requires software testers to operate hardware and understand product hardware-related characteristics such as voltage and current that the software does not care about. Therefore, it will increase the cost and workload of testing, affect the progress of software system testing, and is not conducive to the independent testing of the system by the third party

Embodiment

[0021] The invention utilizes the advantage of the cross-platform operation of the virtual machine technology to realize the simulation of PPC, X86 and other CPUs on the common PC. Realize the whole system simulation of different CPUs on the same platform, so as to realize the goal of the universal design of the environment. In order to achieve good portability and versatility of the platform, standardize the design of the used interface to achieve the maximum reuse of the designed test cases.

[0022] Such as figure 1 As shown, the present invention is a software system testing platform 3 based on virtual machine technology, including four parts: the first part user interface input part 3-1, the second part is the whole system simulation part 3-2 of the target machine under test, and the third part is the interface conversion and communication proxy part 3-4, and the fourth part is the test case pool part 3-3.

Abstract

The invention discloses a virtual machine technique based airborne software system testing general platform which comprises a user interface input part, a to-be-measured target machine full-system simulation part, an interface conversion and communication agent part and a test case pool. According to the invention, based on the virtual machine technique, full-system simulation for to-be-measured equipment is realized, then seamless operation of executable codes of software to be measured in the simulation environment is also realized, and the test software is adopted to realize the software system test platform. The testing general platform can avoid repeated development of test equipment to the utmost, shorten test period, improve test efficiency and reduce test cost.

Description

technical field [0001] The invention belongs to the technical scope of software development, and more specifically, the invention relates to a general platform for testing airborne software systems based on virtual machine technology. Background technique [0002] The existing system test of embedded software is closely related to the specific function of the system, the implementation technology and the platform used, so it is difficult to find a general software system test tool provided by a third party. At present, in the field of avionics, the software system test usually uses specific test equipment to write a specific test program for a specific system, and directly performs the software system test on the target machine. But because different products adopt different CPUs and external interfaces, this test method requires different real system equipment, simulation test equipment, test tools, and test platforms for different systems under test, which lacks versatilit...
