Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle electronic information systems, and in particular relates to a display and control automatic testing system and method based on process injection. Background Art

[0002] As combat tends to develop towards group collaboration and manned / unmanned collaborative technology develops, the equipment that can be controlled by the crew covers manned combat vehicles, unmanned combat vehicles, drones, etc., resulting in a large number of human-machine control devices for the crew. The emergence of display control provides the crew with a good human-machine interaction window, supporting the crew's quick decision-making during combat.

[0003] However, with the growth of the demand for crew control tasks, the crew display and control interface carries too many human-computer interaction windows such as manned platforms, unmanned platforms, and drones. Its complex processing flow, massive real-time data processing, numerous interface controls, and components have led to complex display and control software testing processes and many test data interfaces, which seriously hinder the rapid delivery of display and control software. At the same time, traditional display and control software testing usually requires testers to visually display and verify data input on the display and control interface. Not only is it difficult to quickly locate the position of the information displayed on the display and control interface, but it is also necessary to calculate and verify the displayed data and input data. The test process requires data to be input, displayed, and verified one by one. The test progresses slowly, and it cannot be guaranteed that the process is difficult to achieve 100% credibility. Therefore, there is an urgent need for an automatic testing system and method for display and control software to complete efficient testing of display and control software. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the present invention is: how to propose a display and control automatic testing system and method based on process injection. Based on the current situation that the numerous display and control software interfaces lead to a long testing cycle and it is difficult to meet the rapid delivery requirements, an automatic testing system for display and control software is proposed to solve the difficulties of single display and control software testing means, low testing efficiency, and complex manual testing links, thereby improving the testing efficiency of display and control software.
