Usage-pattern based Statistical Web Testing and Reliability Measurement

With the increasing complexity of Web applications, ensuring the reliability of Web applications becomes an enormous challenge. Statistical Web testing, proposed by researchers in recent years, is an appropriate approach to testing Web applications and to estimating their reliability. However, most of the researchers only focus on estimating the overall reliability of Web applications. They only discuss the failures which are recorded in error log files. In fact, the overall reliability cannot reflect the quality of Web applications under different usage patterns. In this paper, we propose an approach to estimating the particular reliability of Web applications under a particular usage pattern. Moreover, our approach can automatically identify the difference between output and expected pages.
