A concrete starting point
Reduce a fraction of two integers to a positive denominator and coprime terms. Check a negative denominator and a zero numerator, rejecting a zero denominator and non-integer operands before reduction.
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.
