Test Four Threads Running

This is part of JavaUnitTestChallengeSolved. -- DonWells

Now lets try four threads together:


        public class FourThreadsTogether extends Test {

        public BoundedBuffer buffer;

        public PutThread firstPutThread;

        public PutThread secondPutThread;

        public TakeThread firstTakeThread;

        public TakeThread secondTakeThread;


        public void setUp(){

        buffer = new BoundedBuffer();

        firstPutThread = new PutThread(buffer);

        secondPutThread = new PutThread(buffer);

        firstTakeThread = new TakeThread(buffer);

        secondTakeThread = new TakeThread(buffer);}


        public void runTest (){

        TakeThread.resetOutput();

        firstTakeThread.start();

        secondTakeThread.start();

        firstPutThread.start();

        secondPutThread.start();

        waitForTakeToFinish();

        should(TakeThread.doesOuputHaveTwoOf("a"), "should get two a");

        should(TakeThread.doesOuputHaveTwoOf("b"), "should get two b");

        should(TakeThread.doesOuputHaveTwoOf("c"), "should get two c");

        should(TakeThread.doesOuputHaveTwoOf("d"), "should get two d");

        should(TakeThread.doesOuputHaveTwoOf("e"), "should get two e");}


        public void waitForTakeToFinish(){

        try {

        firstTakeThread.join(1000);

        secondTakeThread.join(1000);}

        catch (InterruptedException exception) {};}

        }

I was expecting problems of some sort with this one, but it runs just fine.
