Abstract: A system and method for generating a compatibility score are provided. Elements associated with a web content as rendered by a benchmark browser engine are received. Elements associated with the web content as rendered by the test browser engine are received. The elements of the web content as rendered by the test browser engine are compared with corresponding elements of the web content as rendered by the benchmark browser engine. A compatibility for the web content is generated based on differences from the comparison between the elements of the web content as rendered by the benchmark browser engine and the elements of the web content as rendered by the test browser engine.

Abstract: The subject technology discloses techniques for locating an element in a document object model (DOM) tree structure based on fuzzy matching of attributes of the element and the relative positioning of other elements in the DOM tree structure. For instance, different attributes for searching an element in a DOM tree structure are received. The subject technology determines a location of an element in a DOM tree structure based on the plurality of attributes. A relative location of the element in the DOM tree structure is then determined if determining the location of the element is unsuccessful based on the plurality of attributes. In one example, the relative location of the element is based on fuzzy matching according to a predetermined percentage of one or more matching attributes and based on respective positions of one or more elements in the DOM tree structure.
