Static test flakiness prediction

open access: yesProceedings of the ACM/IEEE 44th International Conference on Software Engineering: Companion Proceedings, 2022
The problem of flakiness occurs when a test case is non-deterministic and exhibits both a passing and failing behavior when run against the same code. Over the last years, the software engineering research community has been working toward defining approaches for detecting and addressing test flakiness, but most of these approaches suffer from ...

Research on the Servo Loading Systems of High Aspect Ratio Wing Test

open access: yesHangkong gongcheng jinzhan, 2019
It occurs that the loading point changes with the test piece in the aircraft structure test. In particularly, the large deformation of the wing will cause the issue that loading point is not perpendicular with the plan of the wing.
