Julien Le Dem updated PIG-2650:
-------------------------------
Description:
A test would look as follows:
{code}
PigServer pigServer = new PigServer(ExecType.LOCAL);
TupleFactory tf = TupleFactory.getInstance();
Data data = Storage.resetData(pigServer.getPigContext());
data.set("foo", Arrays.asList(
tf.newTuple("a"),
tf.newTuple("b"),
tf.newTuple("c")
));
pigServer.registerQuery("A = LOAD 'foo' USING mock.Storage();");
// some complex script to test
pigServer.registerQuery("STORE A INTO 'bar' USING mock.Storage();");
Iterator<Tuple> out = data.get("bar").iterator();
assertEquals("a", out.next().get(0));
assertEquals("b", out.next().get(0));
assertEquals("c", out.next().get(0));
{code}
