TDD is a development methodology that brings us closer to better implementation and testing by repeating a series of steps: test design, implementation that satisfies the tests, and refactoring. This paper proposes a framework aimed at supporting the implementation steps in TDD. The proposed framework generates source code that passes tests while retaining refactoring by the developer. The prototyped framework reduced the time required for the implementation process by 94.22% and the generation time by 66.17% compared to manual work.

It is difficult to understand the structure of large and complex mobile applications. To support iOS app development, we proposed SwiftDiagram, a visualization of the static structure of Swift source code and confirmed its high usefulness. However, manually drawing SwiftDiagram is labor-intensive. This paper implemented a prototype of RAGESS (Real-time Automatic Generation of SwiftDiagram System), a tool that automatically generates SwiftDiagram by performing static analysis on Swift source code every time an iOS app build is successful.

Generating test cases from the formal specification description VDM++, which is a method for disambiguating specifications, is time-consuming and labor intensive. Therefore, our laboratory has developed BWDM, a tool that automatically generates test cases from VDM++ specifications. However, existing BWDM has problems that it only supports integer types and cannot generate test cases for operation and function definitions including recursive structure. Therefore, in order to improve the usefulness of BWDM, this paper extends BWDM to solve the above problems. Consequently, it has confirmed that the use of extended BWDM can reduce the test case generation time compared to manual test case generation.

This paper proposes a prototype of ASLA, segmentation and labeling tool for document images based on deep learning, to reduce the time required for region segmentation and label generation. To evaluate the usefulness of ASLA, we have compared the time required for region segmentation and label generation using ASLA and by hand, and then confirmed the reduction in time. We also have confirmed that the rule-based region redividing method achieves a high recall and precision.

The outbreak of the COVID-19 pandemic changed the model of the learning process. Online learning became one of the best solutions for many educational institutions, including the University, especially the Faculty of Computer Science, Brawijaya University. The continuance intention factor for using an online learning management system is important to ensure learning sustainability. To understand students' continuance intention this study proposes self determination model as a research model to find the factors affecting students' continuance intention toward online learning management systems. The proposed model is useful for investigating continuance intention factors. The study finds that intrinsic regulation, external regulation, identified regulation, and introjected regulation significantly positive impact on continuance intention in learning management systems. Finally, this study provides suggestions for the Faculty to improve the continuance intention of the student in using an online learning management system.

Generating test cases from the VDM++ specification to eliminate ambiguity in the specification is labor-intensive and time-consuming. Therefore, our laboratory developed BWDM, which is an automatic test case generation tool for VDM++ specifications. However, BWDM is not very useful because it has three problems about its narrow scope of application. This paper extends BWDM to solve three problems. In addition, we conducted a comparison experiment with manual test case generation and confirmed a time saving of about 17 minutes.

This paper proposes Gamma, which is a new distributed MQTT system, to improve the usefulness of distributed MQTT systems for sharing spatial data. In the experiment, it has been found that Gamma can process more messages than a single MQTT broker. It is confirmed that Gamma achieves scalability by increasing the number of Gateways and distributed MQTT brokers. Furthermore, it is confirmed that the efficiency of the distributed MQTT system can be improved by setting the responsibility area of Gateways.

Writing VDM++ specifications is difficult. The existing method can automatically generate type and constant definitions in VDM++ specification from natural language specification using machine learning. This paper proposes a method to generate classes and instance variable definitions in the VDM++ specification from natural language specification to improve the usefulness of the existing method. From the evaluation experiment by using F-values, it has been confirmed that the proposed method can improve the usefulness of the existing method.
