Edward Capriolo commented on HIVE-5423:
---------------------------------------
Actually I was able to hide away the boiler plate of setting up the operators
in a base class. Users supply
* sourceTable
* expectedResults
* Expression List
Any easier and it would be harder :)
{code}
public class ExtendedConcatTest extends BaseScalarUdfTest {
@Override
public InspectableObject[] getBaseTable() {
DataBuilder db = new DataBuilder();
db.setColumnNames("a", "b", "c");
db.setColumnTypes(
PrimitiveObjectInspectorFactory.javaStringObjectInspector,
PrimitiveObjectInspectorFactory.javaStringObjectInspector,
PrimitiveObjectInspectorFactory.javaStringObjectInspector);
db.addRow("one", "two", "three");
db.addRow("four","two", "three");
db.addRow( null, "two", "three");
return db.createRows();
}
@Override
public InspectableObject[] getExpectedResult() {
DataBuilder db = new DataBuilder();
db.setColumnNames("_col1", "_col2");
db.setColumnTypes(PrimitiveObjectInspectorFactory.javaStringObjectInspector,
PrimitiveObjectInspectorFactory.javaStringObjectInspector);
db.addRow("one", "onetwo");
db.addRow("four", "fourtwo");
db.addRow(null, null);
return db.createRows();
}
@Override
public List<ExprNodeDesc> getExpressionList() throws UDFArgumentException {
ExprNodeDesc expr1 = OperatorTestUtils.getStringColumn("a");
ExprNodeDesc expr2 = OperatorTestUtils.getStringColumn("b");
ExprNodeDesc exprDesc2 =
TypeCheckProcFactory.DefaultExprProcessor.getFuncExprNodeDesc("concat", expr1,
expr2);
List<ExprNodeDesc> earr = new ArrayList<ExprNodeDesc>();
earr.add(expr1);
earr.add(exprDesc2);
return earr;
}
}
