Cloud-based test modeling and automatic generation of test cases

At present, the design of the test process during the manufacturing process of the aircraft is mainly performed by the process personnel to consult the relevant data of the tested object to obtain the test information, and manually write the test process file. Therefore, the writing efficiency is low and the writing quality relies heavily on the experience of craftsmen, and the standardization and standardization of process files cannot be effectively guaranteed. On the other hand, the test program is closely coupled with specific test equipment. The upgrade and update of test resources cause the test program to change, which increases the use and maintenance costs.This paper proposes to implement standardized modeling of test knowledge based on the Automatic Test Markup Language (IEEE 1671 ATML), to support the sharing, transplantation and reuse of the test information, and to standardize and digitize test process files. At the same time, the automatic generation of signal-oriented test cases is achieved, the interchangeability of test instruments and the portability of test programs are solved, and the universal execution of various test resources is achieved.
