Problems solved by technology

However, the disadvantage of existing browser platform-independent capture / replay technology is that in order to reproduce a JavaScript error, the captured event sequence is usually replayed on the same browser platform, without considering the cross-browser platform Under the circumstances, when the event sequence captured on one browser is replayed on another different browser, the replay may fail or even be wrongly replayed due to an incompatible JavaScript interface call error, which eventually leads to false positives and false positives in the detection results. False report
When the fourth event is dispatched, because the registered callback function cannot be found, the replay fails and affects the correct replay of subsequent events

Abstract

The invention discloses a browser compatibility detection oriented client Web application capture and playback system and method. The method comprises: during an event capture stage, recording various uncertain events generated when a Web application runs in a reference browser platform, and storing causal relationships between external events and internal events, wherein the uncertain events include external user interaction events and browser internal events (such as a timer event, an Ajax message and uncertain function calling); during a playback stage, performing cross-browser remote playback in a test browser platform and collecting page message in the playback process; and performing comparison through information collected from different browsers to detect various compatibility problems. According to the application capture and playback system and method, the accuracy of a detection result can be effectively improved.

Description

technical field [0001] The invention relates to a browser compatibility detection-oriented client web application capturing and replaying system and method, belonging to the technical field of the Internet and the web. Background technique [0002] With the rapid development of the Internet and Web technology, Web applications are becoming an important platform for information acquisition and communication. Application developers hope that applications can perform consistently on various mainstream browser platforms, but due to differences in browser implementation technologies and standards support, web applications may behave differently when running on different browser platforms. Inconsistencies in how pages are rendered are known as cross-browser incompatibilities (XBIs). Generally, cross-browser incompatibility issues (XBIs) fall into three categories: behavioral inconsistencies, layout inconsistencies, and content inconsistencies. Inconsistent behavior: This kind of...
