Worked on the root-project/root repository to enhance the reliability of multi-file data processing in C++ using the ROOT framework. Focused on developing regression tests for the RNTupleProcessor, specifically targeting friendship and join logic across multiple input files to ensure consistent behavior with TTree friendship. Emphasized rigorous unit testing and data processing validation, expanding test coverage to reduce regression risk before releases. The approach improved continuous integration confidence and stability for workflows involving complex file joins. No major bugs were addressed during this period, with efforts concentrated on building robust test infrastructure and verifying cross-file data relationships within the RNTuple framework.
