During November 2025, Duarte Ich worked on the tuist/tuist repository, focusing on enhancing the reliability of command-line interface workflows through improved testing infrastructure. Duarte added SnapshottingTests to the XCTest dependencies, which expanded the test coverage for CLI features and reduced the occurrence of flaky tests. This update, implemented in Swift and leveraging XCTest for test orchestration, aimed to strengthen continuous integration confidence and support more robust release cycles. While no production bugs were addressed during this period, Duarte’s work demonstrated skills in CLI development, dependency management, and collaborative version control, contributing depth to the project’s overall testing strategy.
