Question

I am a beginner in selenium webdrive and try to make a code for gmail login and logout but not able to logout via "Id", it would be helpful for me if anyone suggest that how to logout it. Below are the code which I did please check and suggest:
public class seleniumExample {
public static WebDriver driver;
public static WebElement element, element1;
public static void main(String[] args) {
// TODO Auto-generated method stub
// Intialize chrome driver
driver = new FirefoxDriver();
driver.get("http://www.gmail.com");
element = driver.findElement(By.id("Email"));
element.sendKeys("xyz#gmail.com");
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
element1 = driver.findElement(By.id("Passwd"));
element1.sendKeys("xyz");
element.submit();
driver.findElement(By.id("gbi4m1")).click();
driver.findElement(By.id("gb_71")).click();
}
}

Answer 1

The following id :gbi4m1 does not point to anything. This is causing your test case to fail. As i said before google is not a right place to learn selenium, the page is complex and dynamic id's are hard to deal with if you are beginner.
Normally in browsers you can use development tools to check if a selector can be used to locate an element. So before you actually use a particular selector in your code, you can verify if it works. This will save a lot of time.
One more advantage of using this would be to check the uniqueness of a selector. If there are multiple elements with the same selector,findElement() returns the first one. In this
case the selector would be valid but it won't be unique, which in turn causes your test case to fail.
If a selector is unique, console displays only one element.
Let me explain with a simple example :
To click on Ask Question button on the top right of this page, following selector would work.
css = #nav-askquestion
So now you can confirm this by using the dev tools of your browser.
Just type $('selector_to_check') on the console and it displays all elements related with this selector.
I have used Chrome :
If the selector entered is invalid,an empty array is displayed.

Answer 2

First, id that you are taking doesn't exists. So that won't work. Secondly, once you correctly identify the logout button,it would be a bit more easy for us to identify exact nature of your problem

Answer 3

I'm not sure where did you get "gbi4m1"? anyhow why not use By.className
driver.findElement(By.className("gb_O")).click();
driver.findElement(By.id("gb_71")).click();
Seems to work for me

Answer 4

use cssSelector, Following code work for me
//Click on the profile image present in the right top corner
driver.findElement(By.cssSelector("span.gb_3a.gbii")).click();
//Click on 'Sign Out' button
driver.findElement(By.id("gb_71")).click(); //Close the browser
window driver.close();

Answer 5

this is awesome code for gmail logout in selenium webdriver
driver.findElement(
By.xpath("//*[#id='gb']/div[1]/div[1]/div[2]/div[5]/div[1]/a/span"))
.click();
driver.findElement(By.id("gb_71")).click();

Answer 6

The following code is working for me :-
driver.findElement(
By.xpath("//*[#id='gb']/div[1]/div[1]/div[2]/div[5]/div[1]/a/span"))
.click();
driver.findElement(By.id("gb_71")).click();
I used xpath for finding the account icon and it is working fine for me.
