exceptions in selenium and code to resolve it

Name 5 different exceptions you had in selenium web driver and mention .What instance you got it and how do you resolve it?

·           WebDriverException

·           NoAlertPresentException

·           NoSuchWindowException

·           NoSuchElementException

·           TimeoutException

 • WebDriverException

 WebDriver Exception comes when we try to perform any action on the non-existing

driver.

WebDriver driver = new InternetExplorerDriver();

driver.get("http://google.com");

driver.close();

driver.quit();

• NoAlertPresentException

When we try to perform an action i.e., either accept() or dismiss() which is not required

at a required place; gives us this exception.

try{

driver.switchTo().alert().accept();

}

catch (NoAlertPresentException E){

E.printStackTrace();

}

• NoSuchWindowException

 When we try to switch to an window which is not present gives us this exception:

WebDriver driver = new InternetExplorerDriver();

driver.get("http://google.com");

driver.switchTo().window("Yup_Fail");

driver.close();

In the above snippet, line 3 throws us an exception, as we are trying to switch to an

window that is not present.• NoSuchFrameException

• Similar to Window exception, Frame exception mainly comes during switching between

the frames.

WebDriver driver = new InternetExplorerDriver();

driver.get("http://google.com");

driver.switchTo().frame("F_fail");

driver.close();

In the above snippet, line 3 throws us an exception, as we are trying to switch to an

frame that is not present.

• NoSuchElementException

 This exception is thrown when we WebDriver doesn’t find the web-element in the DOM.

WebDriver driver = new InternetExplorerDriver();

driver.get("http://google.com");

driver.findElement(By.name("fake")).click();

• TimeoutException

 Thrown when a command does not complete in enough time.

All the above exceptions were handled using try catch exceptions.
