A concrete starting point
Enumerate nonattacking queen placements on boards of size zero through eight. Check the empty placement and unsatisfiable small boards, rejecting invalid sizes and testing every row, column and diagonal of returned solutions.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
