Can I get working code for Facebook logout? - facebook

Question

I am not able to find the correct XPath for clicking on Logout in Facebook.
I have been trying for so long to take XPath to click on Logout.
Can anyone please help me out to click on Logout using selenium webdriver with java.
Code trials:
//clicking on navigation bar
driver.findElement(By.id("userNavigationLabel")).click();
System.out.println("Successfully clicked");
//Clicking on logout
driver.findElement(By.xpath("//span[contains(text(),'Log out')]")).click();
//closing the current tab
driver.close();

Answer 1

Are you getting any exception ? like NosuchElement exception or element not found error something like that.
If so, you could wait until the element is visible and then you have to perform the operation.
public void test_01_Logout()
{
WebDriver driver = new FirefoxDriver();
driver.navigate().to("www.facebook.com");
//Add login code here.
waitForElementInDOM(driver, "//div[#id='userNavigationLabel' and
contains(text(),'Account Settings')]", 15);
driver.findElement(By.xpath("//div[#id='userNavigationLabel' and
contains(text(),'Account Settings')]")).click();
waitForElementInDOM(driver, "//span[#class='54nh' and contains(text(),'Log Out')]",
15);
driver.findElement(By.xpath("//span[#class='54nh' and contains(text(),'Log
Out')]")).click();
}
-------------------------------------------------------------------------------------
public void waitForElementInDOM(WebDriver driver,String elementIdentifier, long
timeOutInSeconds)
{
WebDriverWait wait = new WebDriverWait(driver, timeOutInSeconds );
try
{
//this will wait for element to be visible for 15 seconds
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath
(elementIdentifier)));
}
catch(NoSuchElementException e)
{
e.printStackTrace();
}
}

To click on the element with text as Logout you need to use WebDriverWait for the element to be clickable and you can use the following lines of code:
driver.findElement(By.cssSelector("div#userNavigationLabel")).click();
new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("//a[contains(#data-gt, 'menu_logout')]/span/span[normalize-space()='Log Out']"))).click();
