39. How to create a new thread in a Java API-conforming test case

Question

I have a test program looks like this:

public class test {
	public static void main(String args[]) {
	new testThread().start();
	}
}

class testThread extends Thread {
	public void run()
	{
	// the test program is here.
	}
}

Answer

When you create a new thread in a program that uses the TETware Java API, instead of saying

class testThread extends Thread

class testThread extends TetThread

import java.lang.*;
import TET.*;

/* * Test case for threads. */ public class ThrTest extends SimpleTestCase { public static final int SLEEP_TIME = 5;

public static void main(String[] args) { main("ThrTest", args, new ThrTest()); }

public void i1t1(TestSession ts) { TestThread thread;

thread = new TestThread(ts, 1, SLEEP_TIME); thread.start(); ts.tet_infoline("This is the parent thread: " + Thread.currentThread()); ts.tet_infoline("Parent printing child thread: " + thread);

try { thread.join(2 * SLEEP_TIME); } catch (InterruptedException e) { ts.tet_infoline("Caught exception \ while joining child thread:"); ts.tet_infoline(e.toString()); ts.tet_result(ts.TET_UNRESOLVED); }

ts.tet_infoline("parent thread returns"); ts.tet_result(ts.TET_PASS); }

}

class TestThread extends TetThread { private TestSession ts; private int sleepTime;

TestThread(TestSession ts, int id, int sleepTime) { super(ts, "TestThread() #" + id, sleepTime * 1000L); this.ts = ts; this.sleepTime = sleepTime; }

public void run() { ts.tet_infoline("Child thread (" + Thread.currentThread() + "): starting to run");

try { sleep(sleepTime * 1000L); } catch (InterruptedException e) { ts.tet_infoline("Child thread (" + Thread.currentThread() + ") caught exception while sleeping: "); ts.tet_infoline(" " + e); ts.tet_result(ts.TET_UNRESOLVED); }

ts.tet_infoline("Child thread (" + Thread.currentThread() + ") exits"); } }
