@Test public void testToValidationMessageFromDataModelerError() { ArrayList<DataModelerError> dataModelerErrors = new ArrayList<>(); DataModelerError dataModelerError; Level level; for(int i = 0; i < 10; i++) { level = Level.values()[i % 3]; dataModelerError = new DataModelerError(i, "message"+i,level, mock(Path.class), i, i); dataModelerErrors.add(dataModelerError); } List<ValidationMessage> result = serviceHelper.toValidationMessage(dataModelerErrors); assertEquals(dataModelerErrors.size(), result.size()); for (int i = 0; i < dataModelerErrors.size(); i++) { assertErrorEquals(dataModelerErrors.get(i), result.get(i)); } }
