Hello,
Just started looking at SWTBot which looks great. I wondered though why
there didn't seem to be JUnit 4 test runner support? I couldn't see anything
in the source so I created a runner (see patch below) which means you can
start a test like below.
@RunWith(SWTBotRunner.class)
public class FooTest {
private final SWTBot bot = new SWTBot();
@BeforeClass
public static void startTheApplication() throws TimeoutException,
InterruptedException {
new Thread(new Runnable() {
public void run() {
Main.main();
}
}).start();
waitForDisplay(5, SECONDS);
}
@Test
public void rightClickStartsConfiguration() throws Exception {
bot.button("click me").click();
bot.button("you just clicked me!").click();
}
private static void waitForDisplay(long timeout, TimeUnit unit) throws
TimeoutException, InterruptedException {
long endTime = System.currentTimeMillis() + unit.toMillis(timeout);
while (System.currentTimeMillis() < endTime) {
try {
Display display = SWTUtils.display();
if (display != null)
return;
} catch (Exception e) {
}
Thread.sleep(100);
}
throw new TimeoutException("timed out");
}
}
Seems to work for me, does it look about right to you guys?
Cheers,
Toby
