I found the goal interresting, but as the example requires "user" validation (in the sake of simplicity) I think the examples are not realistic enough... I changed the tests and did something like: > public void testHelloWorld() { > ByteArrayOutputStream stream = new > ByteArrayOutputStream(); > PrintStream pStream = > new PrintStream(stream); > System.setOut(pStream); > > System.out.print("Hello, World!"); > > assertEquals("Hello, World!", > stream.toString()); > } The threaded example: > public void testHelloWorld() throws > Throwable { > ByteArrayOutputStream stream = > new ByteArrayOutputStream(); > PrintStream pStream = > new PrintStream(stream); > System.setOut(pStream); > > TestRunnable[] tr = { > new DelayedHello(5000)}; > > MultiThreadedTestRunner mtRunner = > new MultiThreadedTestRunner(tr); > > mtRunner.runTestRunnables(); > > assertEquals("Hello, World!", > stream.toString()); > } The bad one is: > public void testHelloWorld() { > ByteArrayOutputStream stream = > new ByteArrayOutputStream(); > PrintStream pStream = > new PrintStream(stream); > System.setOut(pStream); > > new DelayedHello(5000); > > assertEquals("Hello, World!", > stream.toString()); > }
