An Empirical Analysis of Android Apps Bug and Automated Testing Approach for Android Apps
Yi Bie,Sheng Bin,Gengxin Sun,Xicheng Zhou 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.9
Android platforms and its applications (apps) have gained tremendous popularity recently, hence the reliability of Android apps is becoming increasingly important. Due to the novelty of the Android platform, apps are prone to errors, which would affect user experience and requires frequent bug fixes. In this paper, an empirical study on bugs in some widely-used open-source Android apps from diverse categories such as media, tools and communication were performed. Based on the findings of the empirical study, an approach for automating the testing process for detecting Android apps GUI bugs was presented. We show how the approach helped to re-discover existing bugs and find new bugs, and how it could be used to prevent certain bug categories. Our empirical study and automated testing approach have the potential to help developers increase the quality of Android apps.

Background/Aims: To evaluate the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) for the treatment of symptomatic pancreas divisum (PD) and to discuss whether ERCP procedures and outcomes in younger patients differ from those of adults. Methods: Symptomatic patients with PD were included in the study and divided into underaged (age ≤17 years) and adult (age ≥18 years) group. The clinical information of each patient was reviewed, and then the patients were contacted by telephone or their medical records were reviewed to determine their long-term followup outcomes. Results: A total of 141 procedures were performed in 82 patients (17 underaged and 65 adult patients). The ERCP indications included abdominal pain (39.02%), pancreatitis (12.20%), recurrent pancreatitis (36.59%), and other discomfort (12.20%). The endoscopic interventions included endoscopic pancreatic sphincterotomy in 44.68% of the patients, bouginage in 26.95%, pancreatic ductal stone extraction in 19.15%, endoscopic nasopancreatic drainage in 21.99%, and endoscopic retrograde pancreatic drainage in 56.74%. After a median follow-up of 41 months, the overall response rate was 62.32%. Between the underaged group and the adult group, significant differences were not observed in the ERCP procedures, complications and longterm follow-up results. Conclusions: ERCP is a safe and effective treatment for symptomatic PD. Based on the details, complications, and follow-up results, the ERCP procedure did not present differences between the underaged and adult groups. (Gut Liver 2016;10:476-482)
