Daniel Castillo developed foundational test automation for the RepoSemillerosCodeceptjs repository over a two-month period, focusing on end-to-end testing and maintainable test architecture. He implemented YouTube user flow tests and automated coverage validation for the Telcel website, using JavaScript, CodeceptJS, and the Page Object Model to ensure reliability and scalability. Daniel established project scaffolding and documentation to streamline onboarding and collaboration, while refactoring test structures and normalizing text for consistency. His work enabled earlier detection of UI regressions and improved test maintainability, resulting in faster feedback cycles and more robust validation of core user interactions across web applications.
October 2025: Delivered automated Cobertura Coverage Testing for Telcel website using CodeceptJS. Implemented test framework setup, Page Object Model for the Coverage section, and a scenario validating the interactive map visibility and section title. Refactored test structure and normalized text to improve reliability. Reorganized test assets by moving cobertura.feature to the features directory and aligning Gherkin steps, leading to reduced flakiness and clearer test narratives. Business impact includes earlier detection of UI regressions, more maintainable tests, and faster feedback in CI.
