Worked on the sktime/sktime repository to modularize test configuration for the RandomIntervalSegmenter estimator, focusing on improving test management and maintainability. The approach involved relocating test skip settings from a centralized configuration file to estimator-level tags, which enhanced modularity and reduced the risk of misconfiguration. By aligning test configuration with a tagging-based design, the changes contributed to more predictable and reliable continuous integration runs. This work, implemented in Python and involving software maintenance and testing skills, also improved onboarding for new contributors by clarifying test logic. All modifications were linked to issue #8515, ensuring traceability and collaborative development practices.
