E. Sammer commented on MRUNIT-12:
---------------------------------
Jen:
I haven't yet looked at the patch (on purpose) because you haven't granted the
ASF a license. This would prevent us from including the code in mrunit. If
you'd like to contribute the code, please reupload the patch(es) with the
checkbox labeled "Grant license to ASF for inclusion in ASF works (as per the
Apache License ยง5)" checked.
Thanks!

> Some time we need to test reduce/mapreduce which used MultipleOutputs to
> output,mrunit not support this yet.so, I writed some code support this;
> improvement which make mrunit nicer to use:load test dataset from text and
> some usefull annotation
> example:
> public void testReduce () {
> List<TimeInfo> values = new ArrayList<TimeInfo>();
> values.add(new TimeInfo(1, 3));
> values.add(new TimeInfo(2, 5));
> values.add(new TimeInfo(3, 7));
> reduceDriver.withReducer(reducer)
> .withInput(new Text("444"), values)
> . withMutiOutput ("somePrefix"+444%8,new Text("444"),new
> LongWritable(2))
> .runTest();
> }
>
> load test data from text and use annotation:
>
> @RunWith(MRUnitJunit4TestClassRunner.class)
> public class XXXMRUseAnnotationTest {
> @MapInputSet
> @MapReduce(mapper = Map.class, reducer = Reduce.class)
> private MapReduceDriver<LongWritable, Text, Text, TimeInfo, Text,
> LongWritable> mrDriver;
> @Test
> @MapInputSet("ConsignTimeMRUseAnnotationTest.txt")
> public void testMapReduce_3record_1user() {
> mrDriver. withMutiOutput ("somePrefix"+444%8,new Text("444"),new
> LongWritable(2))
> .runTest();
> }
> }
