Opis:
Context: Automated acceptance testing validates a product’s functionality from the customer’s perspective. Text-based automated acceptance tests (AATs) have gained popularity because they link requirements and testing. Objective: To propose and evaluate a cost-effective systematic reuse process for automated acceptance tests. Method: A systematic approach, method engineering, is used to construct a systematic reuse process for automated acceptance tests. The techniques to support searching, assessing, adapting the reusable tests are proposed and evaluated. The constructed process is evaluated using (i) qualitative feedback from software practitioners and (ii) a demonstration of the process in an industry setting. The process was evaluated for three constraints: performance expectancy, effort expectancy, and facilitating conditions. Results: The process consists of eleven activities that support development for reuse, development with reuse, and assessment of the costs and benefits of reuse. During the evaluation, practitioners found the process a useful method to support reuse. In the industrial demonstration, it was noted that the activities in the solution helped in developing an automated acceptance test with reuse faster than creating a test from scratch i.e., searching, assessment and adaptation parts. Conclusion: The process is found to be useful and relevant to the industry during the preliminary investigation.

Opis:
This paper presents a description of an agile testing process in a medium size software project that is developed using Scrum. The research methods used is the case study were as follows: surveys, quantifiable project data sources and qualitative project members opinions were used for data collection. Challenges related to the testing process regarding a complex project environment and unscheduled releases were identified. Based on the obtained results, we concluded that the described approach addresses well the aforementioned issues. Therefore, recommendations were made with regard to the employed principles of agility, specifically: continuous integration, responding to change, test automation and test driven development. Furthermore, an efficient testing environment that combines a number of test frameworks (e.g. JUnit, Selenium, Jersey Test) with custom-developed simulators is presented.

3TZ environment
Opis:
This paper presents the concepts and explores issues related to the 3 Time Zones (3TZ) model of software development in global workspace environment. The 3TZ model itself seeks to take advantages of differences in time zones between places around the world. By engaging software development teams in different regions separated by 8 hours each, it is possible for their combined working hours to cover the whole 24 hours period. Thus, while they each work their normal 8 hour days, together they are able to achieve in 1 day what a single team would achieve in 3 days. They are able to achieve this by passing on their work from one team to the next as one finishes their workday and the next team starts their workday. The 3TZ model of software development revolves around the employment of a software development team distributed in at least 3 different locations around the world in 3 different time zones. If work was passed on from one team to the next and adjacent teams were separated by 8 hours, then 24 hours continuous collaborative software development could be achieved. Though this poses many challenges, when dealt with there is great potential for software to be developed much faster than is possible for a single, collocated development team. In the global economy, we have seen a decrease in the barriers towards communication across the globe along with an increase of service availability to support this communication. Software development is one of the disciplines that is capable of effectively utilizing and benefiting from global collaboration prospect lent by ever increasing capability of information and communication technology. 24 hours continuous development is ideal for application towards tasks that have hard deadlines or require work completed as soon as possible. This article will mainly focus on introducing 24/7 global models that can be applied in cloud environment used in three different time zones.

Background: Python is a popular and easy-to-use programming language. It is constantly expanding, with new features and libraries being introduced daily for a broad range of applications. This dynamic expansion needs a robust support structure for developers to effectively utilise the language. Aim: In this study we conduct an in-depth analysis focusing on several research topics to understand the theme of Python questions and identify the challenges that developers encounter, using the questions posted on Stack Overflow. Method:We perform a quantitative and qualitative analysis of Python questions in Stack Overflow. Topic Modelling is also used to determine the most popular and difficult topics among developers. Results: The findings of this study revealed a recent surge in questions about scientific computing libraries pandas and TensorFlow. Also, we observed that the discussion of Data Structures and Formats is more popular in the Python community, whereas areas such as Installation, Deployment, and IDE are still challenging. Conclusion: This study can direct the research and development community to put more emphasis on tackling the actual issues that Python programmers are facing.

Opis:
The level of failure of IT projects is high and has not changed over many years despite improvement in software development processes. One of the obvious reasons for this is shortening the delivery time of information systems in the projects and rapidly changing technology. Quality assurance in software development process is a key issue in ensuring the proper operation of an IT system. In order to know the causes of the problems, it is important to know viewpoints of members of the teams developing software. These views were obtained by carrying out the survey. At the beginning categories of reasons are identified using Ishikawa diagram, a tool for quality management. In the next step an analysis was performed using the Pareto principle. The analysis allowed the identification of the most important causes of errors in the software development process. A detailed analysis of the observed results and appropriate conclusions of this analysis will help improve the processes of software development and collaboration between project management and software development processes.

In a modern urban organization, mobility is an important issue for society. Traffic congestion of urban roads undermines mobility is a real problem in major cities This article shows the development and implementation of a centralized traffic control system in the city of Cali Valle (Colombia) applied to control traffic lights located to the east of the city (Simon Bolivar and Ciudad de Cali highways), allowing the central operators directly influence the traffic flow, know and display the status of the lights and generate statistics about the events of the online equipment. Particular real benefits of proposed new system of traffic lights are reflected in green times at each intersection allocated in accordance with the present traffic volumes on the road network at any time of day and in every sector of the city in particular, which of course increases the efficiency of each light installed at each intersection. As demonstrated in this article case study, the congestion scheme has been improved, and the project has opened up vast opportunities for innovative network management strategies for the optimization of network performance. Many of these strategies are developed to give a coordinated high-level control across different traffic control platforms based on real time traffic condition and performance on site.

Opis:
Agile methods for project management are often treated as methods for mitigating risk. However, there is disagreement as to whether explicit methods of risk management should be used in projects which are executed according to Agile methodology or is the implicit risk management built into Agile methodologies sufficient. To contribute to the discussion, an attempt has been made to identify risks that are either caused by the introduction of an Agile methodology to a project or become more significant when such methodology is in use. If such risks exist, this would be evidence that explicit risk management is required, even in the case of Agile methodologies. The results of this research may be useful for any organization that is in the process of selecting a methodology for project management and is considering Agile methodologies.

Opis:
Research background: The twin pressures of economic downturn and climate change faced by countries around the world have become more pronounced over the past decade. A renewable energy transition is believed to play a central role in mitigating the economic-climate paradox. While the architectural and computational power of artificial intelligence is particularly well suited to address the challenges of massive data processing and demand forecasting during a renewable energy transition, there is very scant empirical assessment that takes a social science perspective and explores the effects of AI development on the energy transition. Purpose of the article: This paper aims to answer two key questions: One is, how does AI software development promote or inhibit the shift of energy consumption towards renewables? The other is, under what policy interventions does AI software development have a more positive effect on promoting renewable energy consumption? Methods: We employ a dataset of 62 economies covering the period 2011–2020 to analyze the impact of AI software development on the energy transition, where possible confounders, including political and economic characteristics and time-invariant elements, are controlled using fixed-effects estimation along with specified covariates. Findings & value added: AI software development can promote the energy transition towards renewables. There is suggestive evidence that the core mechanism linking such a positive relationship tends to lie in improving innovation performance in environmental monitoring rather than in green computing. Government support for R&D in renewable energy technologies is found to be significantly beneficial for harnessing the positive impact of AI software development on the energy transition. Compared to non-market-based environmental policies, market-based environmental policies have a more significant positive moderating effect on the relationship between AI software development and energy transition.
