When I saw that the one put and ten take test had failed, I thought that this test should also have failed. I am thinking that perhaps it has to do with the threads dying after 5 inputs or outputs. So I can just go ahead and change the take threads so that they all stay alive during the whole test.

 public class T''''''wentyThreadsTogether extends Test {
    public BoundedBuffer buffer;
    public P''''''utThread putThreads [];
    public T''''''akeThread takeThreads [];
    
    public void setUp(){
        buffer = new BoundedBuffer();
        putThreads = new P''''''utThread [10];
        takeThreads = new T''''''akeThread [10];
        for (int each = 0; each < 10; each++) {
            putThreads[each] = new P''''''utThread(buffer);
            takeThreads[each] = new T''''''akeThread(buffer, 50);};}
        
    public void tearDown(){
        T''''''akeThread.dumpOutput();}
    
    public void runTest (){
        T''''''akeThread.resetOutput();
        for (int each = 0; each < 10; each++) {
            takeThreads[each].start();};
        for (int each = 0; each < 10; each++) {
            putThreads[each].start();};
        waitForPutToFinish();
        sleepHalfSecond();
        should(T''''''akeThread.outputLength() == 50, "output was too short");
        should(T''''''akeThread.doesOuputHaveTenOf("a"), "should get ten a");
        should(T''''''akeThread.doesOuputHaveTenOf("b"), "should get ten b");
        should(T''''''akeThread.doesOuputHaveTenOf("c"), "should get ten c");
        should(T''''''akeThread.doesOuputHaveTenOf("d"), "should get ten d");
        should(T''''''akeThread.doesOuputHaveTenOf("e"), "should get ten e");}
        
    public void waitForPutToFinish(){
        try {
            for (int each = 0; each < 10; each++) {
                putThreads[each].join(4000);}}
        catch (InterruptedException exception) {};}
        
  }
This test fails now.

Interesting thing though. Sometimes it fails in a different way. Every so often it completely deadlocks.

And every so often it will in fact pass.

What I can do for this is ExtendTheJavaTestFrameworkForNondeterminism.
