Problems solved by technology

[0004] Due to the current testing methods for virtual instruments, testers need to artificially compare whether the display data of each display control of the virtual instrument is the same as the display data sent by the flight simulator system. Whether the control data received by the simulator system is the same, so the test cycle is long and error-prone

Abstract

The invention provides a testing method and device for a virtual instrument. Testing data corresponding to a control to be tested are read from a testing file and sent to the control to be tested corresponding to the data in the virtual instrument; and result data returned by the control to be tested of the virtual instrument are received, so that a closed loop between a testing system and the virtual instrument is formed. Whether each item of the sent data is the same with each item of the received data or not is compared, and if each item of the sent data is the same with each item of the received data, testing passes, otherwise, the control to be tested in the virtual instrument is abnormal. The virtual instrument can be tested without the need that a tester compares whether input data and output data of each control of the virtual instrument are same one by one, and therefore, the testing efficiency and the accuracy of a testing result are improved.

Description

Technical field [0001] The invention belongs to the technical field of testing, and in particular relates to a testing method and device of a virtual instrument. Background technique [0002] Virtual instruments are widely used in the aerospace field to display a large amount of information such as flight status and flight characteristics in real time. With the widespread application of virtual instruments, how to carry out efficient tests on virtual instruments is particularly important. [0003] At present, the test method for virtual instruments is to establish a connection between the virtual instrument and the flight simulator system through a communication interface, and the flight simulator system sends display data to the virtual instrument. After the virtual instrument receives the display data, it displays on the corresponding display control. The tester then judges whether the display control of the virtual instrument can display the data in real time and accurately by ...
