Worked on the wazuh/wazuh repository to enhance reliability by developing unit tests for Agcom command handling, focusing on verifying correct responses across a range of input scenarios. Applied C programming and CMake to implement and integrate these tests, emphasizing robust test-driven development and clear commit practices. The effort targeted improved test coverage for critical command paths, aiming to detect regressions early and support maintainable code. No major bugs were addressed during this period, with the primary contribution centered on quality assurance and faster iteration cycles. This work contributed to greater confidence in releases and streamlined future development within the project.
