Model-based GUI testing provides an effective mechanism for automated testing of applications with a GUI. However, most existing model-based GUI test generation techniques produce many infeasible (i.e., Broken) event sequences which are used as test cases. This happens primarily because they ignore behavioral specifications of the GUI under test. In this paper, we present an automated black box framework that reveals an important set of GUI invariants as state-based event constraints. GUIDiVa, an iterative algorithm at the core of our framework, enumerates all possible constraint violations as potential reasons of a test case failure, on the failed event of the infeasible test case. It further selects and adds the most promising constraints of each iteration to a final set based on our notion of constraint Validity Weight. The results of empirical studies on both seeded and nine non-trivial study subjects show that our framework is capable of capturing important aspects of GUI behavior, while considerably reducing the number of insfeasible test cases. Additionally, a human oracle is used to further validate the accuracy of the discovered constraints.","PeriodicalId":106871,"journal":{"name":"2014 IEEE 38th Annual Computer Software and Applications Conference","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116578558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At that time, they try to obtain information on the smart phones. In order to search the information of the attractive phrases on web pages, they have to manipulate the smart phones to search on the small screen. It causes stresses because of situations such as manipulation errors. Such stresses could be eliminated if the attractive phrases can be identified and be input automatically in order to recommend the web pages with the information of the attractive phrases. Because of the small screens of smart phones, users move the news article area displayed on the screens with touch gestures such as swipe. The history of touch gestures during browsing an article implies the position and the timing users have focused on in the article. This paper proposes a method to identify the areas where attractive phrases have appeared on news articles, in order to enable automatic identification of attractive phrases. We have achieved real-time identification by utilizing the history of touch gestures during a web news browsing. The proposed method shows the history of touch gestures by a gesture trail. It is a graph showing the time series of the vertical coordinate of the displayed article area. When users encounter attractive phrases, they take certain patterns of touch gestures to confirm or read carefully the neighborhood of the attractive phrases. Thus, in the proposed method, the news article area including an attractive phrase is detected by matching the gesture trail in a sliding time window with a pattern obtained by pre-training. We use slow-down and resting patterns approximated by quadratic functions with the parameters defined for individual users. Experiments to identify time windows of attractive phrases on gesture trails has revealed that the highest and the lowest precision ratios are 0.579 and 0.278, respectively.","PeriodicalId":106871,"journal":{"name":"2014 IEEE 38th Annual Computer Software and Applications Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133518772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, transmission speed through a wireless network often slows down in comparison with that through a wired network since packets of wireless networks frequently drop due to the influence of surrounding environment such as electromagnetic noise. In this paper, we propose a method to mitigate the impacts caused by packet loss by virtue of SCTP bicasting in lossy multihoming environment with two or more wireless networks. This method bicasts not all packets but only important packets concerning retransmission for efficiency since bicasting all packets would cause congestion. We also implemented a prototype system based on the proposed method. According to the result of performance evaluation experiment, we confirmed the effectiveness of the proposed method by the fact that the prototype system performed faster transmission than normal SCTP transmission even in high packet loss rate environment.","PeriodicalId":106871,"journal":{"name":"2014 IEEE 38th Annual Computer Software and Applications Conference","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131073911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inam","doi":"10.1109/COMPSAC.2014.42","DOIUrl":"https://doi.org/10.1109/COMPSAC.2014.42","url":null,"abstract":"In real-time embedded systems the components and components integration must satisfy both functional correctness and extra-functional correctness, such as satisfying timing properties. Deploying multiple real-time components on a physical node poses timing problems in components's integration. These timing problems during integration further effect predictability and reusability of real-time components. We propose a novel concept of runnable virtual node (RVN) whose interaction with the environment is bounded both by a functional and a temporal interface, and the validity of its internal temporal behaviour is preserved when integrated with other components or when reused in a new environment. Our realization of RVN exploits the latest techniques for hierarchical scheduling framework to achieve temporal isolation, and the principles from component-based software-engineering to achieve functional isolation. Proof-of-concept case studies executed on an AVR based 32-bit micro-controller demonstrates the preserving of real-time properties within components for predictable integration and reusability in a new environment without altering its temporal behaviour in both hierarchical scheduling and RVN contexts. We also take a step ahead towards expanding the performance preserving servers' concept for multicore platform on which the scheduling of real-time tasks is inherently unpredictable due to the contention for shared physical memory and caches. It results in proposing and implementation of a novel type of server, called Multi-Resource Server (MRS) which controls the access to both CPU and memory bandwidth resources such that the execution of real-time tasks become predictable. The MRS provides temporal isolation both between tasks running on the same core, as well as, between tasks running on different cores. Further, we provide the schedulability analysis for MRS to provide predictable performance when composing multiple components on a shared multi-core platform.","PeriodicalId":106871,"journal":{"name":"2014 IEEE 38th Annual Computer Software and Applications Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123909918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When new bugs are submitted, triagers have to find and assign appropriate developers to fix the bugs. However, if the bugs are at first assigned to inappropriate developers, they may later have to be reassigned to other developers. That increases the time and cost for fixing bugs. Therefore, finding appropriate developers becomes a key to bug resolution. When triagers assign a new bug report, it is necessary to decide how quickly the bug report should be addressed. Thus, the bug severity is an important factor in bug fixing. In this paper, we propose a novel method for the bug triage and bug severity prediction. First, we extract topic(s) from historical bug reports in the bug repository and find bug reports related to each topic. When a new bug report arrives, we decide the topic(s) to which the report belongs. Then we utilize multi-feature to identify corresponding reports that have the same multi-feature (e.g., Component, product, priority and severity) with the new bug report. Thus, given a new bug report, we are able to recommend the most appropriate developer to fix each bug and predict its severity. To evaluate our approach, we not only measured the effectiveness of our study by using about 30,000 golden bug reports extracted from three open source projects (Eclipse, Mozilla, and Net beans), but also compared some related studies. The results show that our approach is likely to effectively recommend the appropriate developer to fix the given bug and predict its severity.","PeriodicalId":106871,"journal":{"name":"2014 IEEE 38th Annual Computer Software and Applications Conference","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122516058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
