How to handle Javascript Alerts or web-based pop-ups?
To handle Javascript Alerts, WebDriver provides an Interface called Alert.
First, we need to switch the driver focus to alerts.
Syntax:
Alert alert=driver.switchTo().alerts();
alert.getText() – The getText() method retrieves the text displayed on the alert box.
alert.accept() – The accept() method clicks on the “Ok” button as soon as the pop-up window appears.
alert.dismiss() – The accept() method clicks on the “Cancel” button as soon as the pop-up window appears.
alert.sendKeys(String stringToSend) – The sendKeys() method enters the specified string pattern into the alert box.

What are the different types of Waits or Synchrinization commands in WebDriver?
Usually, the time delay between two webdriver elements is 0 milliseconds but the application speed varies based on different factors:
Internet speed
Server response time
System configuration
To avoid the timing errors(Synchronization errors) between the tool (webdriver) and application, we take the help of Synchronization commands.
Implicit Wait: It is used to define wait for all the elements of WebDriver.
Syntax:
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
Explicit Wait: It is used to define wait for specific element of WebDriver.
Syntax:
WebDriverWait wait=new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.elementToBeClickable(By.linkText(“Gmail”)));

What is the difference between Assert and Verify in Selenium?
There is no difference between Assert and Verify in a positive scenario.

Verify: If the verify condition is true then the program control will execute the next test step but if the condition is false, the execution of the current step will be skipped and further test step will be executed.

Can you explain Junit Annotation? If there are 1000 test cases. 500 test cases are executed. How will you execute the rest of the test cases by using annotation?
The annotations generated with JUnit 4 tests in Selenium are:
@Before public void method() – Will perform the method() before each test. This method can prepare the test
@Test public void method() – Annotation @Test identifies that this method is a test method.environment,e.g. read input data, initialize the class)
@After public void method() – Test method must start with test@Before – this annotation is used for executing a method before
Difference between assert and verify in selenium web driver.
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.
