示例2: testProgram

@Override
protected void testProgram() throws Exception {

* This test checks the interplay between the monitor and the reader
* and also the failExternally() functionality. To test the latter we
* set the parallelism to 1 so that we have the chaining between the sink,
* which throws the SuccessException to signal the end of the test, and the
* reader.
