Worked on stabilizing the test infrastructure for the avocado-framework/avocado-vt repository by addressing log file management during virtual machine login attempts. Applied Python scripting and system testing skills to implement a targeted fix that removes session log files when login failures occur, ensuring that only successful login sessions generate logs. This approach reduced unnecessary disk usage and mitigated privacy concerns associated with lingering log files. The update improved test reliability and developer productivity by preventing stale logs from affecting results. The work demonstrated a focus on code hygiene and maintainability within the virtualization testing environment, emphasizing robust and predictable continuous integration behavior.
