AJAX allows the Web page to retrieve small amounts of data from the server without reloading the entire page.
To test Ajax application, different wait methods should be applied
ThreadSleep
Implicit Wait
Explicit Wait
WebdriverWait
Fluent Wait
How do you execute your framework from command prompt?
Home-directory > java org,testng.TestNG testng.xml testng2.xml testng2.xml and hit enter
Difference between WebDriver Listener and TestNG listener.
TestNG and Web driver Listener have different interfaces to implement and call them.
WebDriver Event Listener is to listen the events triggered by web driver like beforeClickOn, afterClickOn, beforeFindBy, afterFindBy, etc. and take actions. It is mainly used to write log file for selenium test execution.
TestNG listener mainly used to generate the report for the test. Also, you can capture screenshot when there is test failure. TestNG events are like onTestFailure, onTestSkipped, onTestSuccess, etc.

When will you get element not clickable exception in Selenium?
The reason for the element is not clickable at point(x,y) exception.
Some of my observation was
It mostly happens in Chrome so if you are mostly working with Firefox or IE then you will not be getting this exception.
Chrome does not calculate the exact location of element
Chrome always click in the middle of Element.
Sometimes you will get this exception due to Sync issue also.
How to solve Not connected Exception – unable to connect to host in selenium webdriver?
Scripts that worked earlier may be till yesterday are NOW not working because of Firefox browser upgraded to new version.
Most of them have faced the similar problem when the browser has updated to version. This is the first issue user notices when there is an update in the Firefox browser and may not support selenium with the older version of jars.
If you already have the latest version of selenium, then you have to degrade your browser until there is an update from selenium.
Problem :
Webdriver will just initiate the browser, prompting for a search or address and that ends there with an exception:
org.openqa.selenium.firefox.NotConnectedException:
What is Selenium?
Selenium is a Suite (group) of tools i.e., Selenium IDE, Selenium WebDriver and Selenium Grid to automate web browsers across many platforms.
What is Selenium IDE, WebDriver, and Grid?
Selenium IDE: It is a Firefox plugin which is used to Record and Play the Test Scripts.
Selenium WebDriver: It is a tool which provides an API (that can be understood easily) to automate web browsers with the help of programming languages like Java, Csharp, Python, PHP, Perl, Ruby, and JavaScript.
Selenium Grid: It transparently distributes tests into Remote machines. That is, running multiple tests at the same time against different machines running different browsers and operating systems.
What are the locators available in WebDriver?
Locators: Locators are used to identifying or locate an element (text box, radio buttons, links, check boxes, drop downs, images, text etc. ) in the web page.
Webdriver supports 8 locators i.e., Id, Name, Class Name, Link Text, Partial Link Text, XPath, CSS and Tag Name.
Note: Id is the fastest locator among this 8 locators.
How to launch Firefox, Chrome, IE browser using WebDriver?
The following syntax can be used to launch Browser:
WebDriver driver = new FirefoxDriver();
WebDriver driver = new ChromeDriver();
WebDriver driver = new InternetExplorerDriver();
How to switch between frames?
WebDriver’s driver.switchTo().frame() method takes one of the three possible arguments:
A number.
Select a frame by its (zero-based) index. That is, if a page has three frames, the first frame would be at index “0”, the second at index “1” and the third at index “2”. Once the frame has been selected, all subsequent calls on the WebDriver interface are made to that frame.
A name or ID.
Select a frame by its name or ID. Frames located by matching name attributes are always given precedence over those matched by ID.
A previously found WebElement.
Select a frame using its previously located WebElement. Get the frame by it’s id/name or locate it by driver.findElement() and you’ll be good.

In TestNG I have some test’s Test1-Test2-Test3-Test4-Test5I want to run my execution order is Test5-Test1-Test3-Test2-Test4.How do you set the execution order can you explain for that?
Use priority parameter in @test annotation or TestNG annotations.
public class testngexecution { @Test(priority=2)public void test1(){System.out.print(“Inside Test1”); }@Test(priority=4)public void test2(){System.out.print(“Inside Test2”); }@Test(priority=3)public void test3(){System.out.print(“Inside Test3”); }@Test(priority=5)public void test4(){System.out.print(“Inside Test4”); }@Test(priority=1)public void test5(){System.out.print(“Inside Test5”); }

jxl has not been maintained properly while ApachePOI is more up to date.
Sample code on Apache POI is easily available as compare to jxl.
How to ZIP files in Selenium with an Example?
// Sample Function to make zip of reports

String files[] = inputFolder.list();
for (int j=0; j<files.length; i++)
{
in = new BufferedInputStream(new FileInputStream
(inputFolder.getPath() + “/” + files[j]), 1000);
out.putNextEntry(new ZipEntry(files[j]));
int totalcount;
while((totalcount= in.read(data,0,1000)) != -1)
{
out.write(data, 0, totalcount);
}
out.closeEntry();
}
