Test Case Prioritization Due to Database Changes in Web Applications

Abstract

A regression test case prioritization (TCP) technique reorders test cases for regression testing to achieve early fault detection. Most TCP techniques have been developed for regression testing of source code in an application. Most web applications rely on a database server for serving client requests. Any changes in the database result in erroneous client interactions and may bring down the entire web application. However, most prioritization techniques are unsuitable for prioritizing test suites for early detection of changes in databases. There are very few proposals in the literature for prioritization of test cases that can detect faults in the database early. We propose a new automated TCP technique for web applications that automatically identifies the database changes, prioritizes test cases related to database changes and executes them in priority order to detect faults early.
