SEMERU Android Developer Tools
Welcome to the home page for the SEMERU set of Android development tools. This site is a portal to research projects and tools created by the SEMERU Research group at the College of William & Mary and collaborators. Our goal is to build useful, practical tools for developers to help improve the process of software creation, maintenance, and testing for mobile applications (with a focus on Android) by leveraging emerging program analysis, information retrieval, and machine learning techniques. Our tools have been published at top research venues (including ICSE, FSE, and ICST), and we actively collaborate with industrial partners to apply solutions from academic research to problems faced by real world mobile developers.
Fusion - Improving Bug Reporting for Mobile Applications
Bug reporting systems have not changed significantly in recent years. Despite striking advancements in program analysis techniques, reporters typically enter textual information to describe a bug. However, this type of report has been shown to be woefully inadequate for developers looking to reproduce and fix reported bugs. The goal of the Fusion project is to leverage static and dynamic program analyses to improve the bug reporting process and produce higher quality reports with more detailed information, while requiring less effort from reporters.
ODBR - On Device Bug Reporting for Android Apps
Bugs that surface in mobile applications can be difficult to reproduce and fix due to several confounding factors such as varyiable contextual states, and device fragmentation. Developers need support in the form of automated tools that allow for more precise reporting of application defects in order to facilitate more efficient and effective bug fixes. The ODBR tool leverages the uiautomator framework and low-level event stream capture to offer support for recording and replaying a series of input gesture and sensor events that accuratley describe a bug in an Android application.
CrashScope- Effective Automated Testing for Android Applications
Automated testing techniques for Android exhibit notable shortcomings including: (i) A lack of expressive fault reports, (ii) lack of testing for contextual features (e.g. GPS, network), (iii) multiple input generation strategies. CrashScope aims to overcome these shortcomings by using static analysis to identify GUI-specific locations where contextual features exist and multiple input generation strategies to effectively test these locations and uncover crashes. When the tool crashes a target application, it generates an expressive report with the steps for reproduction and a repayable test script. Thus, CrashScope is an effective and practical automated testing tool for Android.
