Though, not exactly what you are asking for - There is a
getTuplesFromConstantTupleStrings function in
test//org/apache/pig/test/Util.java that converts string representation
of tuples to tuple objects. It is an easier way and more maintainable
way of creating tuples in test cases.
For example - List<Tuple> expectedRes =
Util.getTuplesFromConstantTupleStrings(
new String[] {
"(10,20,30,40L)",
"(11,21,31,41L)",
});
But not exposed as public interface right now. It make sense to make it
part of a public interface.

Thanks for your response. Yes I am using those in my udf eval function.
Actually my quesiton was around how do I build the tuple? Is there a
utility method that would let me build my tuple with the following record
type. I need to populate the tuple in below format so that I can pass it in
the unit test. It's tab delimited and also has bags.

Something like this (not tested):
List<Tuple> bagtuples = Lists.newArrayList();
// populate inner tuples, then...
DataBag myBag = BagFactory.getInstance().newBag(bagtuples);
Tuple t = TupleFactory.getInstance().newTuple(myBag);

Thanks! I am trying to figure out how to create a Tuble object that also
has bags in it. I have a record like this that I want to pass to UDF as a
tuple. Any info would be very helpful.

Hi Mohit,
We just write standard Java unit tests for pig UDFs. You can see a ton
of them here:
https://github.com/apache/pig/blob/trunk/test/org/apache/pig/test/TestStringUDFs.java
Does that help?

Is there a way I can just unit test my pig UDF? What's the best way to
unit
test in pig. I saw pigunittest but couldn't find a way to unit test
udf.
