close(): This method is used to close the current active window of the browser.
quit(): This method is used to close all the associated windows of the browser that are opened.
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”)));

By using moveToElement() method in Actions class
//Create an object to Actions class
Actions action = new Actions(driver);
action.moveToElement(element);

What is the difference between “/” and “//”
Single Slash “/” – Single slash is used to create XPath with absolute path i.e. it locates the element from the root node.
Example:
/html/body/div[2]/div[4]/table/tbody/tr[4]/td/span
Double Slash “//” – Double slash is used to create XPath with relative path i.e. it locates the element from the current node.
Example:
//input[@name=’email’]
What is the difference between Assert and Verify in Selenium?
There is no difference between Assert and Verify in a positive scenario.
Assert: If the assert condition is true then the program control will execute the next test step but if the condition is false, the execution will stop and further test step will not be executed.
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.
What is the super interface of WebDriver?
SearchContext is the super interface of WebDriver
How many ways can we load a web page?
We can load a webpage(url) in two ways:
driver.get(“URL”);
driver.navigatr().to(“URL”);
Can we run group of test cases using TestNG?
Test cases in group in Selenium using TestNG will be executed with the below options.
If you want to execute the test cases based on one of the group like regression test or smoke test
@Test(groups = {“regressiontest”, “smoketest”})
In what all case we have to go for “JavaScript executor”.
Consider FB main page after you login. When u scrolls down, the updates get loaded. To
handle this activity, there is no selenium command. So you can go for javascript to set
the scroll down value like driver.executeScript(“window.scrollBy(0,200)”, “”);
What are the test types supported by Selenium?
Selenium supports UI and functional testing. As well it can support performance testing
for reasonable load using selenium grid.
What are the different assertions in SIDE?
Assertions are like Assessors, but they verify that the state of the application conforms to what is expected. Examples include “make sure the page title is X” and “verify that this check box is checked”.
Assertions are like Accessors, but they verify that the state of the application conforms to what is expected. Examples include “make sure the page title is X” and “verify that this checkbox is checked”.
All Selenium Assertions can be used in 3 modes: “assert”, “verify”, and “waitFor”.
For example, you can “assertText”, “verifyText” and “waitForText”. When an “assert” fails, the test is aborted. When a “verify” fails, the test will continue execution, logging the failure. This allows a single “assert” to ensure that the application is on the correct page, followed by a bunch of “verify” assertions to test form field values, labels, etc.
“waitFor” commands wait for some condition to become true (which can be useful for testing Ajax applications). They will succeed immediately if the condition is already true. However, they will fail and halt the test if the condition does not become true within the current timeout setting (see the setTimeout action below).
How to store a value which is text box using web driver?

How to handle alerts and confirmation boxes.
Confirmation boxes and Alerts are handled in same way in selenium.
var alert = driver.switchTo().alert();
alert.dismiss(); //Click Cancel or Close window operation
alert.accept(); //Click OK
Handle Confirmation boxes via JavaScript,
driver.executeScript(“window.confirm = function(message){return true;};”);

action.moveToElement(we).moveToElement(webdriver.findElement(By.xpath(“/expression-here”))).click().build().perform();
