Abstract: 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.
