/**
|
||
* Tests de las fórmulas "Ahorro esperado" y "Eficiencia" de ComparisonTable (Sprint 5, Etapa 5).
|
||
* expectedSavings = savings × executionProbability
|
||
* efficiency = expectedSavings / executionTimeMinutes
|
||
* Reglas de null: no automatable → null; savings <= 0 → null; efficiency además requiere
|
||
* executionTimeMinutes > 0.
|
||
*
|
||
* Las fórmulas viven inline en el useMemo de ComparisonTable.tsx (no hay función pura
|
||
* exportada — por scope de la etapa no se modifica el dominio). Estos tests replican
|
||
* exactamente esa lógica para verificar las fórmulas y las reglas de null/ranking.
