### Question:
ColumnMappingSupport implements EnvSupport { @Override public List<DataElement> getRecords(DataTypeInfo type) { return myElementProvider.getDataElements(type); } ColumnMappingSupport(DataElementLookupUtils elementProvider, ColumnMappingController mappingController); @Override String columnMatch(Col column1, Col column2); @Override List<DataElement> getRecords(DataTypeInfo type);  }### Answer:
@Test public void testGetRecords() { EasyMockSupport support = new EasyMockSupport(); ColumnMappingController mapper = support.createMock(ColumnMappingController.class); DataTypeInfo type = support.createMock(DataTypeInfo.class); List<DataElement> elements = createElements(support); DataElementLookupUtils lookup = createLookup(support, type, elements); support.replayAll(); ColumnMappingSupport mappingSupport = new ColumnMappingSupport(lookup, mapper); assertEquals(elements, mappingSupport.getRecords(type)); support.verifyAll(); }
