Testes automatizados em APIs REST: proposta de arquitetura e melhores práticas de projeto

Abstract

With the widespread adoption of agile development practices, test automation has become a cornerstone to the quality assurance process inmodern systems. Particularly in the context of the growing use of REST APIs in distributed and microservices-based architectures, test automation stands out as a fundamental practice to ensure the quality of these systems. This study aimed to analyze and implement automated testing practices in REST APIs through a modular, flexible and scalable architecture proposal. Themethodology includes a practical case study using a recipe manage ment API as the object of analysis. Additionally, the study seeks to provide an overview of automated testing in EST APIs, addressing challenges, best practices, the importance of well-defined requirements, and the use of quantitativemetrics for result evaluation. The results showed a 93.33% success rate in the implemented tests, with 85.96% of the functional requirements validated. The quantitativemetrics highlight the effectiveness of test automation in defect detection, as well as its applicability in regression and confirmation tests. Finally, it is concluded that the proposed architecture is effective and test automation in REST APIs is indispensable, especially in projects with high frequency ofmodifications.
