Context: The popularity of microservices architecture has grown due to its ability to address monolithic architecture issues, such as limited scalability, hard maintenance, and technological dependence. Nonetheless, the migration of monolith systems to microservices is complex. Therefore, methodologies and techniques are needed to facilitate migration and support practitioners and software architects. Objective: The objective of this study is to investigate cases of application migration, microservices identification techniques, tools used during migration, factors that promote migration, as well as issues and benefits of the migration. Method: We have conducted this SMS following the guidelines established by Kitchenham and Petersen. The research objective was defined using part of the Goal-Question-Metric model and the Population, Intervention, and Outcome criteria. From 1546 studies that were retrieved from the search execution , 114 were selected and analyzed to answer the research questions. Results: This SMS contributes with (i) a migration process proposal based on migration cases, (ii) a characterization of migration techniques based on different criteria, (iii) an analysis of tools to support migration, (iv) the identification of migration drivers, and (v) an exploration of migration issues as well as benefits. Conclusion: This SMS sheds light on the complexity and variability of migrating monolithic systems to microservices, as well as the limited number of migration tools. While scalability and maintenance drive migration, few studies assess them. Key challenges include microservices communication and database migration , with most research focusing primarily on monolith decomposition. Despite these difficulties, migration offers benefits, particularly in scalability and maintainability .

A demonstration of the application and contribution of Test-Driven Development (TDD) and Behavior-Driven Development (BDD) in the student learning experience in the context of a Software Engineering course. Background: Software testing is an activity for ensuring software quality. Although teaching testing rigorously to students is a priority in academia, undergraduate students often encounter difficulties performing testing tasks effectively. Intended Outcomes: To increase satisfaction rate and course grades, and reduce delivery time. Application Design: We experimented with the Software Engineering Laboratory (LES) course of a Private University in the Bachelor of Computer Science and Information Systems courses. This experiment corroborated the learning difficulties of students. Collected data were assessed both quantitatively and qualitatively. Findings: Backed up with statistical tests, the results showed a reduction in student absences, higher student satisfaction rate, and higher grades in the courses. Furthermore, our approach allowed students to deliver a product in a short period, representing a possibility of adoption of BDD due to their successful learning experience. Finally, we aim to foster a discussion of appropriate teaching methods of software testing.

Context: Socioeconomic development has accelerated the urbanization process and the advance of Information and Communication Technologies (ICT). In this context, population growth in urban centers manifested challenges in the economic and cultural aspects of society. Issues such as mobility and sustainability come up. ICT plays an important role in this scenario, as it enables innovative services to citizens to improve their quality of life. Objective: To identify and analyze technological solutions (tools, services, applications or products) of urban public monitoring in order to characterize them, with respect to smart cities and ubiquitous devices, from the point of view of researchers and public agents in the field. context of theoretical and applied research in the literature. Method: A Systematic Literature Mapping (SLM) was performed to characterize the research in the area. Results: It was found that most studies treat as important and global trend urban public monitoring through ubiquitous devices in the context of smart cities. Conclusion: Urban public monitoring can be performed through appropriate ICT infrastructures, using devices such as sensors to capture and transmit data in real-time. This communication takes place without the use of wires and it is necessary to worry about the energy efficiency and accuracy of these ubiquitous devices. This way, the city can become more efficient and attractive to its citizens.
