PROFILE
Sandra María Castro
Worked on the casangi/xradio repository, focusing on enhancing testing infrastructure, data validation, and code quality for astronomy software workflows. Over five months, delivered new features and bug fixes by expanding schema validation coverage, modernizing the testing framework, and improving test reliability. Applied Python and pytest to implement robust unit tests, modularize testing utilities, and ensure data integrity through schema validation and error handling. Refactored code for maintainability, standardized formatting with Black, and consolidated documentation to streamline onboarding. These efforts improved CI reliability, reduced maintenance overhead, and enabled safer, faster iteration cycles for future development and scientific data processing tasks.

Feb 1, 2026Month: 2026-02 — casangi/xradio 1) Key features delivered - Schema Validation Testing Coverage Expansion: Added 61 new test cases to improve schema validation robustness, covering dimension validation, dataset registration, and error handling for invalid inputs, increasing test coverage and confidence for future changes. 2) Major bugs fixed - Schema Validation Robustness: Type and Return Value Handling (Bug Fix): Corrects wrong type usage, incorrect annotation key, and wrong variable in check.py; ensures validated types align with the schema and return values are properly checked. Accompanied by targeted tests. 3) Overall impact and accomplishments - Improved data integrity and reliability of schema validation, reducing risk of invalid data propagating through the pipeline. - Strengthened test suite with substantial coverage expansion, enabling safer refactors and faster iterations for future schema-related work. - Clear traceability to commits enabling quick review and rollback if needed. 4) Technologies/skills demonstrated - Python, robust schema validation patterns, and type handling. - Test-driven development with extensive pytest-based coverage. - Debugging, code quality improvements, and reinforcing CI readiness for casangi/xradio.

Dec 1, 2025December 2025 monthly summary for casangi/xradio focusing on testing infrastructure and modularity improvements. Delivered a dedicated XRADIO Testing Module with casacore dependencies to improve modularity and usability, along with expanded fixtures and examples for unit tests and ASV benchmarks. Reorganized testing utilities, consolidating test code into a single testing module and moving test/_utils into the new module. Updated core test harness (conftest.py, __init__.py) and aligned test_conversion to use the new structure. Documentation updates were performed to reflect the new testing module and consolidated docs across test and testing README files. These changes improve test coverage, maintainability, and onboarding for new contributors while laying groundwork for CI/testing improvements.

May 1, 2025May 2025 focused on strengthening test coverage and data integrity for casangi/xradio ProcessingSetXdt ephemeris handling. Expanded unit tests for ephemeris data, including empty datasets, axis querying (summary/dimension/frequency), and interpolation of ephemeris fields. Added a dedicated test for get_combined_field_and_source_xds and updated the input ephemeris Measurement Set to richer fields. A Black formatting fix was applied to align with CI standards, along with minor test-formatting improvements to reduce CI noise. No production defects reported; work improves reliability, maintainability, and confidence in ephemeris data workflows.
