Commencez par les opérateurs conditionnels et arithmétiques : ils révèlent les failles de couverture les plus courantes. Pour un projet complexe, activez le mode « incremental » de Stryker ou l’option `--skip-covered` de mutmut afin d’éviter les mutants redondants. Un score < 70 % indique des tests trop génériques : ciblez les mutants survivants dans les `if` et les boucles pour ajouter des cas limites précis.
