摘要： A power connector includes a housing and a clamp group disposed in the housing. An insertion opening is formed at one end of the housing, and the insertion opening is configured to plug in a plug. The clamp group includes an inner clamp and an outer clamp. An insertion slot is formed in the inner clamp, and the insertion slot is opposite to the insertion opening and is configured to accommodate a front end portion of the plug. The outer clamp is disposed to extend over the inner clamp. When the plug passes through the insertion opening and is plugged into the insertion slot, a contact end of the outer clamp close to the insertion opening presses against a conductive surface of the plug. A contact segment of the inner clamp also presses against the conductive surface of the plug.

摘要： Embodiments of the present invention provide a page testing method and a page testing apparatus. The page testing method is used to test a page. The method includes: reading a test sentence used to indicate a page element and a test action; searching for a position where the page element is located on the page according to source code of the page; executing the test action in the position; and verifying an execution result of the test action to obtain a test result. According to the embodiments of the present invention, no action function is needed and instead, a specified test action is triggered directly. Therefore, the complexities of developing and using test software are reduced.
