Desarrollo de un sistema web para automatizar el proceso de compra y venta en la microempresa raza utilizando la tecnología Laravel y Vue.js bajo un enfoque de desarrollo dirigido por pruebas (TDD).

Abstract

The objective of this degree work was to develop a web system to automate the buying and selling process in the commercial microenterprise "Raza" applying a test-guided development approach (TDD). In the system requirement phase, 29 user stories and 8 technical stories were obtained, which were planned and developed with the SCRUM methodology, it allowed to get a greater productivity and software quality, especially since it facilitated to do the tasks independently. In order to facilitate the maintainability and scalability of the system, the Model Controller View Pattern was used; Free license tools such as PHP programming language, the MySQL database manager were used, and the application server was XAMP for system development; due to its extensive documentation and with the objective of lowering costs. As a final result, the purchase and sale system was obtained, which requires minimum resources from the client for its operation; On the other hand, two studies were carried out to verify a reduction in time in relation to the manual and automated process, respectively. Within the analyzed processes a reduction in time was obtained from 25% to 91%. Because the studies show normal distributions with statistically significant differences, it is concluded that there is a real reduction of the time in the execution of the processes after the implementation of the web system. Finally, it is recommended to use the TDD technique because it uses a framework focusing on the system design and the business logic, which helps minimize the number of errors, provides confidence and prepares the software for any modification.
