Abstract
An integrated view of the information system has been an objective to deal with complexity. However, bibliography proposes many solutions with many synonyms depending on the layer, methodology, framework or tool used, that does not allow a broad view of the system. In this work we chose three basic elements of the information systems and we demonstrate how they are enough to integrate a set of essential UML diagrams. The proposed model firstly defines a set of UML diagrams for each layer of the Enterprise Architecture, and then heuristic rules are detailed in order to ensure vertical and horizontal alignment. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract
The advances in mobile computing and the market demand for new products which meet an increasingly public represent the importance to assure the quality of mobile applications. In this context, automated GUI testing has become highlighted in research. However, studies indicate that there are still limitations to achieve a large number of possible combinations of operations, transitions, functionality coverage, and failures reproduction. In this paper, a Deep Q-Network-based android application GUI testing tool (DeepGUIT) is proposed to test case generation for android mobile apps, guiding the exploration by code coverage value and new activities. The tool was evaluated with 15 open-source mobile applications. The obtained results showed higher code coverage than the state-of-the-art tools Monkey (61% average higher) and Q-testing (47% average higher), in addition, a greater number of failures.
