    The English Proficiency Index results from 2024 show that the Spanish-speaking population has limited English proficiency. This deficiency has an impact on the population's academic training, as well as on job opportunities. Promoting early English language learning in Spanish-speaking children is essential to ensure comprehensive development at this crucial stage. The methodology proposed in this study focuses on creating an attractive and friendly user experience using design principles based on usability engineering to maximize learning effectiveness. This research aims to solve the problem related to information retention and friendly interaction for Spanish-speaking children aged six to eight years with an educational video game for learning English. The application aims to promote English learning from an early age, taking advantage of children's innate abilities to absorb a language effectively during this development phase. In this research work, an educational video game was designed to ensure that it is usable at all stages of development, from requirements specification to design, coding, and usability testing. Additionally, usability tests were conducted to evaluate the interface and the level of information retention. The results show that the video game developed using the proposed methodology complies with the usability principles.

    In the last decade, both the mobile market and app development have seen exponential growth, with millions of apps in online stores and billions of downloads recorded. Several development processes are used for app development, with agile approaches being the best fit for the market model. However, there is a weakness in testing activities and tasks. To provide a tool to improve software quality, we present a proposal for a framework for software testing in apps. Our proposal combines a series of tools used to evaluate an application in key areas such as consistency, security, compatibility, stress, among others, the development activities that provide a deliverable, and Mobile Ilities. To evaluate the feasibility of using the proposal, a toy app was used. The results reflect situations where the app’s behavior is not desired and its relationship with mobile ilities. The main contribution of the paper is to guide app developers in evaluating apps and contributing to improving app quality.
