Outline of Final Research Achievements	The purpose of this study is to tackle the problem where Web applications frequently change and the development and maintenance costs of Web application tests are high. To achieve the purpose, we found that the PageObjects design pattern could improve the maintainability of Web application tests, and then, we developed a novel Web testing framework named DePoT including a new internal domain specific language for helping developers to employ the PageObjects design pattern. We evaluated DePoT and found that DePoT could reduce the development and maintenance costs of Web application tests. In addition, we successfully developed a new test input generation techniques named Feedback-controlled Random Test Generation and a new extraction method for Web pages as application studies.
