If you want to quickly add this behavior to ALL your tests in the run you can use the RunListener interface to listen for test failures.

public class ScreenshotListener extends RunListener {

    private TakesScreenshot screenshotTaker;

    @Override
    public void testFailure(Failure failure) throws Exception {
        File file = screenshotTaker.getScreenshotAs(OutputType.File);
        // do something with your file
    }

}

Add the listener to your test runner like this...

JUnitCore junit = new JUnitCore();
junit.addListener(new ScreenshotListener((TakesScreenShots) webDriver));

// then run your test...

Result result = junit.run(Request.classes(FullTestSuite.class));
