JUnit

If you are using JUnit to execute, you can extend the TestWatcher class:

public class TestRules extends TestWatcher {

    @Override
    protected void failed(Throwable e, Description description) {
        // This will be called whenever a test fails.
    }

So in your test class you can simply call it:

public class testClass{

@Rule
public TestRules testRules = new TestRules();

@Test
public void doTestSomething() throws Exception{
    // If the test fails for any reason, it will be caught be testrules.
}

EventFiringWebDriver

Using the EventFiringWebDriver. You can attach WebDriverEventListener to it and override methodes, ie the onException method:

EventFiringWebDriver driver = new EventFiringWebDriver(new FirefoxDriver());
WebDriverEventListener listener = new AbstractWebDriverEventListener() {
    @Override
    public void onException(Throwable t, WebDriver driver) {
        // Take action
    }
};
driver.register(listener);
