### Question:
SegmentProperties { public int[] getDimColumnsCardinality() { return dimColumnsCardinality; } SegmentProperties(List<ColumnSchema> columnsInTable, int[] columnCardinality); int[] getDimensionColumnsValueSize(); KeyGenerator getDimensionKeyGenerator(); List<CarbonDimension> getDimensions(); List<CarbonDimension> getComplexDimensions(); List<CarbonMeasure> getMeasures(); int[] getDimColumnsCardinality(); int[] getComplexDimColumnCardinality(); Map<Integer, Integer> getDimensionOrdinalToBlockMapping(); Map<Integer, Integer> getMeasuresOrdinalToBlockMapping(); int[] getEachDimColumnValueSize(); int[] getEachComplexDimColumnValueSize(); ColumnarSplitter getFixedLengthKeySplitter(); Map<Integer, KeyGenerator> getColumnGroupAndItsKeygenartor(); int getNumberOfNoDictionaryDimension(); int[][] getColumnGroups(); ColumnGroupModel getColumnGroupModel(); int getColumnGroupMdKeyOrdinal(int colGrpId, int ordinal); int getNoOfColumnsInColumnGroup(int colGrpId); Set<Integer> getDimensionOrdinalForBlock(int blockIndex);  }### Answer:
@Test public void testBlockMetadataHasProperDimensionCardinality() { int[] cardinality = { 100, 102, 103, 105, 106, 107 }; boolean isProper = true; for (int i = 0; i < cardinality.length; i++) { isProper = cardinality[i] == blockMetadataInfos.getDimColumnsCardinality()[i]; if (!isProper) { assertTrue(false); } } assertTrue(true); }
