Abstract: Automating testing or use of an application under test (AUT) is greatly simplified when domain object model (DOM) information is available. However, DOM information is not always available. Systems and methods are provided wherein graphical elements are identified and converted to computer code. The computer code is applied to a transparent layer and as a user visually interacts with the AUT, the transparent layer identifies the inputs and the root graphical elements. The inputs are then forwarded to the root graphical elements. The inputs and target graphical elements may be recorded and played back (as-is or modified) on the same or different AUT. The playback then allows a specific graphical element to receive a particular input, even if DOM information remains unavailable.

The irreversible expansion of the coating itself is used to fix the magnet in the magnetic steel groove. Meanwhile, the use of the expandable coating shortens the assembly time of motors and improves the assembly accuracy of the motors.

Abstract: A coating composition, a preparation method therefor and use thereof are provided. The coating composition includes at least 60% heat-expandable microspheres having a wall thickness of less than or equal to 5 ?m, a water-based thermoplastic resin, a water-based thermosetting resin, and a hot-melt filling resin. Thin-shell spheres can be quickly softened and ruptured within a short time in the heat-expansion process, and with the volatilization of an organic solvent, the coating composition cross-links with a resin matrix in the coating to form a cross-linked network structure, thus strengthening the gap support of the coating, and enabling the coating to achieve stepped expansion. After expansion, some polymer materials wrap an airbag and harden to form a stable hollow structure. Therefore, the expanded coating can be used for the fixation of high temperature-resistant parts, and can maintain adhesive stability when placed in a high-temperature environment (140-180° C.) for a long time.
