When an “assert” fails, the test will be aborted. Assert is best used when the check value has to pass for the test to be able to continue to run log in.
Where if a “verify” fails, the test will continue executing and logging the failure. Verify is best used to check non critical things. Like the presence of a headline element.

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.
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.
