Aim of our ongoing-work has been to investigate, define and apply a variety of analysis and testing techniques able to support the quality of Web applications. Validity of our solutions was assessed by extensive empirical work.
A critical review of this five year long work shows that only 40% of the randomly selected real-world Web applications exhibit no anomalies/failures. Some tables reported in this paper summarize the relations between type of anomalies found and analyses applied.
We are in need of better methodologies, techniques and tools for developing, maintaining and testing Web applications.
