How to use getSupportUrl method of org.openqa.selenium.WebDriverException class

Select any element on IFrame which takes maximum time to load e.g. any button or image and the wait using the following code.

WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.visibilityOfElementLocated((By
                .name("element"))));

Or rather you can wait for for iFrame to appear and then switch to it and then use the above statement !

The error is being thrown by webdriver's get method that is navigating you to the url that you provided. Most probably your URL is missing a protocol. So a wild guess would be, that you are passing url as www.example.com, but what you want to give is http://www.example.com

Attribute validationMessage will return the message, that will be showing if validation fails:

WebElement username = driver.findElement(By.name("uname"));    
String validationMessage = username.getAttribute("validationMessage");

If element has required attribute, browser will show the message after submitting the form:

boolean required = Boolean.parseBoolean(username.getAttribute("required"));

You can check whether entered value is valid:

boolean valid = (Boolean)((JavascriptExecutor)driver).executeScript("return arguments[0].validity.valid;", username);

---

Not: message text and validation is customizable. If you want to test customized validation and message.

Here test code for custom validation(Java, TestNG):

Assert.assertTrue(Boolean.parseBoolean(username.getAttribute("required")), "Username is required and message should be showin");
Assert.assertEquals(username.getAttribute("validationMessage"), "My custom message", "Message text control");

username.sendKeys("@vasya ");
Assert.assertTrue((Boolean)((JavascriptExecutor)driver).executeScript("return arguments[0].validity.valid;", username), "Username has special characters");

The problem was with my IE settings. The problem was resolved when the security settings in IE was changed to "Enable Protected Mode" for "Internet", "Local Intranet", "Trusted Sites" and "Restricted Sites". You can change it by going to Internet Options security tab and enable check box "Enable Protected Mode" for all the zones. I was able to get these information from the link http://jimevansmusic.blogspot.in/2012/08/youre-doing-it-wrong-protected-mode-and.html

Create cookies using the Java API as follows:

Cookie ck = new Cookie("name", "value");
driver.manage().addCookie(ck);

Create cookies using the Python API as follows:

driver.add_cookie({'name': 'foo', 'value': 'bar'})

You can try creating a File instance and getting the absolute path from there.

File file = new File("src/test/resources/testData/twt_Pic.jpg");
yourElement.sendKeys(file.getAbsolutePath());

Just use //element[@someAttribute] for your XPath expression.

The lock screen will deactivate the other script of our program. So I tried open the emulator manually and disable the lock screen (Settings -> Security -> None). Then close the emulator. Now open the emulator automatically and run the script.

public void setUp(int p) throws MalformedURLException {
    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability(CapabilityType.BROWSER_NAME, "browser");
    capabilities.setCapability(CapabilityType.VERSION, "");
    capabilities.setCapability(CapabilityType.PLATFORM, "windows");
    capabilities.setCapability("platformName", "Android");
    capabilities.setCapability("udid", "emulator-" + p);
    capabilities.setCapability("devices", "Android");
    capabilities.setCapability("avd", "Nexus7");
    capabilities.setCapability("deviceName", "");
    capabilities.setCapability("appPackage", "com.android.browser");
    capabilities.setCapability("appActivity", "com.android.browser.BrowserActivity");
    driver = new RemoteWebDriver(new URL("http://127.0.0.1:" + this.port + "/wd/hub"), 
             capabilities);
}

I will provide you code in Python for this. I think it's easy to translate to Java:

def scroll_down(self):
    """A method for scrolling the page."""

    # Get scroll height.
    last_height = self.driver.execute_script("return document.body.scrollHeight")

    while True:

        # Scroll down to the bottom.
        self.driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")

        # Wait to load the page.
        time.sleep(2)

        # Calculate new scroll height and compare with last scroll height.
        new_height = self.driver.execute_script("return document.body.scrollHeight")

        if new_height == last_height:

            break

        last_height = new_height

Hope it helps you!
