An Enhanced Pairwise Search Approach for Generating Optimum Number of Test Data and Reduce Execution Time

In recent days testing considers the most important task for building software that is free from error. Since the resources and time is limited to produce software, hence, it is not possible of performing exhaustive tests (i.e. to test all possible combinations of input data.) An alternative to get ride from this type exhaustive numbers and as well to reduce cost, an approach called Pairwise (2 way) test data generation approach will be effective. Most of the software faults in pairwise approach caused by unusual combination of input data.  Hence, the demand for the optimization of number of generated test-cases and reducing the execution time is growing in software industries. This paper proposes an enhancement in pairwise search approach which generates optimum number of input values for testing purposes.  In this approach it searches the most coverable pairs by pairing parameters and adopts one-test-at-a-time strategy for constructing a final test-suite.  Compared to other existing strategies, Our proposed approach is effective in terms of number of generated test cases and of execution time.

Improvement opportunity in Agile Methodology and a survey on the adoption rate of the Improved Methodology

Agile method promotes an iterative process on software development. It is a lightweight process that employs short iterative cycles, actively involve users and developers to establish, prioritize, and verify requirements and rely on a team’s tacit knowledge as opposed to documentation. In this paper we describe the existing agile methodologies and improve its different parameters so that software development industries can adopt it more easily. It describes the improvement of overall understanding of the constituent parts of agile systems development methodologies and some improvement of different parameters. In our proposed method we design a Tool of adoption matrix which will help software development industries for adoption decision solution of the Improved Agile Methodology. We have described the result of different software workshop where the adoption assessment will be used to assess the existing agile system and the improved agile system. The result from this tool will help software industries to apply the improved agile methodologies. Keywords: Agile Methodology, Adoption decision, Adoption assess tool, Improvement of Agile

An Improved & Adaptive Software Development Methodology

The methods of software development have increased a lot from the beginning. From the first waterfall to current agile methodology there still have some drawbacks. For this reason, the software delivery is still a very challenging and heavy-duty work. In this paper, we proposed a new software development methodology which is easy to implement and will help software development companies a secure and robust software releases. The proposed SDLC process is known as 4A. The empirical result shows that the proposed methodology is more adaptive and flexible for developers and project managers

Maternal HealthCare Using IoT-Based Integrated Medical Device: Bangladesh Perspective

Purpose: The main purpose of this study is to develop a low-cost integrated medical device. This device will help investigate the risk levels of maternal patients as well will reduce the cost involved in medical diagnosis for poor countries like Bangladesh, where maternal healthcare is a great concern. Methodology: We proposed and developed an integrated medical device that includes all possible sensors to collect raw data from maternal patients. As soon as the data is collected it will be sent to the cloud for processing. In the cloud, there are a set of algorithms (software) for processing raw data received from the device. After processing and analyzing our system will automatically identify the risk levels of those patients. The software is developed in open source code so that in the future it can be updated by researchers. Results: We developed the system and practically collected raw data from patients and uploaded those data to our cloud system. In the cloud, it was processed and the resultant data were presented in the form of graphs. From these graphs, the risk levels were identified. Limitations: The proposed system is developed for maternal patients only. This system needs to be authorized by the health regulatory authority. To make it cost-effective some expensive sensors were not used. Contribution: The main contribution of this study is to minimize the cost involved in maternal healthcare in poor countries like Bangladesh. This, in turn, controls the death of mother and child by improving maternal healthcare facilities
