DartUnit: ferramenta para teste de arquitetura em aplicativos Dart e Flutter

Abstract

The development of cross-platform systems has grown significantly due to the demand for applications capable of supporting different platforms from a single codebase. In this context, Flutter, a framework developed by Google and combined with the Dart language, stands out for its productivity, performance, and ease of maintenance in the development of mobile, web, and desktop applications. Despite the growing adoption of Flutter in cross-platform application development, there is a lack of specific solutions for automated architectural compliance verification within this ecosystem, making it difficult to maintain the structural consistency of systems and contributing to the increase of technical debt, improper coupling between components, and maintenance costs, a scenario further aggravated by the growing use of artificial intelligence tools for automatic code generation. In this context, the objective of this work is to develop DartUnit, a software architecture testing tool for Flutter and Dart applications, capable of automatically verifying the architectural compliance of projects through automated tests. To achieve this, a qualitative, applied, and exploratory research approach was adopted, conducted in stages involving the analysis of consolidated architectural testing tools, the iterative development of the tool, and its evaluation in real Flutter projects. As a result, a tool capable of automating the validation of architectural rules related to package organization, layer dependencies, and structural conventions was obtained, enabling the early detection of architectural violations and contributing to the improvement of the maintainability, scalability, and sustainability of cross-platform applications.
