This paper proposes a crawling method for A JAX. The main contributions of the paper are:• An analysis of the key problems involved in crawlingA JAX applications;• A systematic process and algorithm to infer a state machine from an A JAX application, which can be used to11Mesbah et. al. – Crawling AJAX by Inferring User Interface State Changesgenerate a static mirror site. Challenges addressed include the identification of clickable elements, the detection of DOM changes, and the construction of thestate machine;• The open source tool C RAWLJAX, which implementsthis process;• Six case studies used to evaluate the effectiveness, correctness, performance, and scalability of the proposedapproach.Although we have been focusing on A JAX in this paper,we believe that the approach could be applied to any DOMbased web application.Future work consists of conducting more case studies toimprove the ability of finding clickables in different A JAXsettings.
The fact that the tool is available for download foreveryone, will help to identify exciting case studies. Furthermore, strengthening the tool by extending its functionality, improving the performance, and the state explosionoptimization are other directions we foresee. Exposing thehidden-web induced by A JAX using C RAWLJAX and conducting automatic state-based testing of A JAX applicationbased on the reverse engineering techniques are other applications we will be working on.References[1] A.
