### Question:
ListUIModelMapperHelper { public static ListSection getSection(final int columnIndex) { switch (columnIndex) { case 0: return ListSection.ROW_INDEX; case 1: return ListSection.EXPRESSION; default: return ListSection.NONE; } }  static ListSection getSection(final int columnIndex); static final int ROW_COLUMN_INDEX; static final int EXPRESSION_COLUMN_INDEX; }### Answer:
@Test public void testGetSectionNoneLessThanMinimum() { assertEquals(ListSection.NONE, getSection(ListUIModelMapperHelper.ROW_COLUMN_INDEX - 1)); }
@Test public void testGetSectionNoneMoreThanMaximum() { assertEquals(ListSection.NONE, getSection(ListUIModelMapperHelper.EXPRESSION_COLUMN_INDEX + 1)); }
@Test public void testGetSectionRowNumberColumn() { assertEquals(ListSection.ROW_INDEX, getSection(ListUIModelMapperHelper.ROW_COLUMN_INDEX)); }
@Test public void testGetSectionExpressionColumn() { assertEquals(ListSection.EXPRESSION, getSection(ListUIModelMapperHelper.EXPRESSION_COLUMN_INDEX)); }
