Mocking Java InputStream

Question

Please provide pointers to help me mock that java InputStream object. This is the line of code that I would wish to Mock:

InputStreamReader inputData = new InputStreamReader(System.in);
bufferdReader = new BufferedReader(inputData);
bufferdReader.readLine();

You could use commons-io to create some stub input streams:

InputStream stubInputStream = 
     IOUtils.toInputStream("some test data for my input stream", "UTF-8");
