I am trying to test my standalone application with SWTBot. I can start an Eclipse workbench (using the plugin example), but there is nothing in it. I thought about loading my application, but decided there must be an easier way. Please let me know if I am wrong. I can run junit4 tests, but I can not get an SWTBot to see my applicaiton. So what do I need to do to get the junit tests and SWTBot together? I am using Eclipse Helios 3.6, version 2.0.0.595-dev-e36 of SWTBot, and junit4.

When I uncomment the bot in PPSOpen.beforeClass, I get
java.lang.IllegalStateException: Could not find a display

I run the following as a junit test
I have AllTests.java

package test;

import org.junit.runner.RunWith;
import org.junit.runners.Suite;

@RunWith(Suite.class)
@Suite.SuiteClasses({
PPSOpen.class,
OtherTests.class,
PPSClose.class,
})
public class AllTests {

} // AllTests

PPSOpen.java

package test;

import static org.eclipse.swtbot.swt.finder.waits.Conditions.shellIsActive ;


public class PPSOpen
{
private static SWTWorkbenchBot bot = null;

public static SWTWorkbenchBot getBot()
{
return bot;
}

@Before
public void beforeClass() throws Exception {
// bot = new SWTWorkbenchBot();
}

@Test(timeout=6000)
public void initPPS()
{
try
{
PPS.main(new String[] { });
}
catch (Exception e)
{
e.printStackTrace();
fail("initialize PPS failed");
}

//ICondition waitForWidget = shellIsActive("PPS");
// bot.waitUntilWidgetAppears(waitForWidget);
}

@Test
public void getPPS()
{
PPS pps = Setup.getPps();
assertNotNull("PPS is null", pps);
}
}

and PPSClose.java

package test;

import org.junit.* ;


public class PPSClose
{
@Test
public void closePPS()
{
PPS.getDisplay().syncExec(new Runnable() {
@Override
public void run()
{
PPS pps = Setup.getPps();
assertTrue(pps != null);
pps.close();
}

});
}
}

See SWTBotApplicationLauncherClassRunner: http://goo.gl/g4ae

Also you'd need to use SWTBot class and not SWTWorkbenchBot for SWT only
tests. SWTWorkbenchBot is for eclipse based tests.

Thank you very much for your help. I was confused about what to do because I develop in Eclipse, so SWTWorkbenchBot seemed like the right thing to use. The example code for SWTBotApplicationLauncher should be updated to:

import org.eclipse.swtbot.swt.finder.junit.SWTBotApplicationLaunche rClassRunner;

public class FooApplicationTestClassRunner extends SWTBotApplicationLauncherClassRunner
{
public FooApplicationTestClassRunner(Class<?> klass) throws Exception
{
super(klass);
}


@Override
public void startApplication()
{
Foo.main(new String[] { "arguments", "to", "your application" });
}
}
