For each of a number of test commands of a test script for browser-based load testing of a web application hosted by a server device communicatively connected to the test device over a network, the test command is executed within a browser instance running on the test device and simulating usage of the web application by a user. In response to determining that the test command that has been executed is a browser operation command, that the test command executes for a minimum length of time is ensured in a throttling test mode in which the web application is tested via the browser instance.

Throttling test mode for browser-based web application load testing

This document describes techniques and apparatuses for supporting web components associated with a document object model (DOM) corresponding to a data file in a web testing environment. A user interaction, relative to a web page or web application from which the DOM is rendered, is monitored in the web testing environment. The monitoring identifies a target element selected by the user that is referenced in a shadow DOM associated with the DOM. One or more parent shadow host elements of the DOM are identified relative to the target element. The one or more shadow host elements define a reduced path, with respect to a tree data structure representing the DOM and the shadow DOM, for linking a document object of the DOM to the target element. Indicia identifying the one or more shadow host elements as linking the document object of the DOM to the target element are recorded. The recorded indicia define the reduced path for identifying the target element relative to the document object in the tree data structure during a replay of a recorded session of the user interaction. A target element may also be identified and replaced with a different object by referencing the one or more shadow host elements.

The present invention discloses a inspection device for detecting a defect of a metal object, where the inspection device includes a main base, at least one main magnetic module, and a main inspection module. The at least one main magnetic module is installed on the main base, for attaching the main base onto the metal object under an action of a magnetic force. The main inspection module is installed on the main base, to detect at least one type of defect of the metal object. The present invention further discloses a wheel defect inspection method and a wheel defect inspection device. The metal object defect inspection device may implement automatic detection of a defect on a whole circumference of a wheel.

Embodiments described herein provide circuitry for reducing input distortion at a buffer due to large signal swings. The circuitry includes an analog-to-digital converter (ADC), a first buffer, a low pass filter, and a second buffer. The ADC is configured to convert an analog input to a digital output. The first buffer is coupled to an input node of the ADC and the low pass filter is coupled to an output of a driving circuit and an input to the first buffer. The second buffer placed in proximity to the first buffer. An input of the second buffer is connected to an output of the driving circuit and an output of the second buffer is connected to a feedback component of the driving circuit.

The present application discloses a parking guidance system. The parking guidance system is mounted on a vehicle and includes a camera, a display device with a display correction system, a parking mode selection apparatus, a parking area selection apparatus, a first turning guidance apparatus, and a second turning guidance apparatus. The camera is mounted at the rear of the vehicle to capture the image showing environment behind the vehicle. The display device with a display correction system is coupled to the camera and is configured to display an image corrected by the display correction system. The parking mode selection apparatus is coupled to the display device. The parking mode selection apparatus displays a predicted parking area on the display device. The parking area selection apparatus is coupled to the display device. The parking area selection apparatus displays a parking guidance area on the display device. The first turning guidance apparatus is coupled to the display device. The first turning guidance apparatus displays an arc on the display device. The second turning guidance apparatus is coupled to the display device. The second turning guidance apparatus displays on the display device a parking track with distance indication.

A vehicle handling assistant apparatus is discloses, the vehicle handling assistant apparatus utilizes an environment acquisition means to acquire an environment signal and utilizes an environment presentation means to present the environment signal. The vehicle handling assistant apparatus also utilizes an obstacle detection means to detect an obstacle from the environment signal acquired by the environment acquisition means and output an obstacle signal. The obstacle detection means may be implemented by an infrared sensor, a radar sensor, an ultrasonic sensor or a camera. An obstacle region generation means generates an obstacle region signal from the environment signal based on the obstacle signal generated by the obstacle detection means. The obstacle region signal includes information about a position of the foot point line and a width of the obstacle region. An environment signal adjustment means adjusts the environment signal presented by the environment presentation means based on the obstacle region signal.
