### Question:
LedgersSpiPaymentMapperHelper { static int mapPisDayOfExecution(PisDayOfExecution dayOfExecution) { if (dayOfExecution == null) { return DEFAULT_DAY_OF_EXECUTION; } return Integer.parseInt(dayOfExecution.getValue()); } private  LedgersSpiPaymentMapperHelper();   }### Answer:
@Test void mapPisDayOfExecution() { assertEquals(1, LedgersSpiPaymentMapperHelper.mapPisDayOfExecution(null)); for (PisDayOfExecution execution : PisDayOfExecution.values()) { assertEquals(Integer.parseInt(execution.getValue()), LedgersSpiPaymentMapperHelper.mapPisDayOfExecution(execution)); } }
