WebDriverSessionHandler { public WebDriverSessionHandler(RemoteWebDriver driver) { if (driver == null) { throw new IllegalArgumentException("RemoteWebDriver instance is null"); } this.driver = driver; webDriverCaller = new WebDriverCaller(); } WebDriverSessionHandler(RemoteWebDriver driver); void start(); void stop();  }### Answer:
@Test(groups = "functional") @WebTest public void testWebDriverSessionHandler() throws ExecutionException, InterruptedException, IOException { Grid.driver().get(TestServerUtils.getTestEditableURL()); TextField normalTextField = new TextField(TestObjectRepository.TEXT_AREA_LOCATOR.getValue()); String sTest = "Testing multi line text for TextArea object"; WebDriverSessionHandler m = new WebDriverSessionHandler(Grid.driver()); m.start(); Thread.sleep(1000 * 60 * 3); m.stop(); normalTextField.type(sTest); assertTrue(normalTextField.getText().contains(sTest), "Validate GetText method"); }
