Ques 2) How do you read data from excel ?

FileInputStream fis = new FileInputStream(“path of excel file”);

 Workbook wb = WorkbookFactory.create(fis);

 Sheet s = wb.getSheet(“sheetName”);

 String value = s.getRow(rowNum).getCell(cellNum).getStringCellValue();

Ques 3) What is the use of xpath ?

Ans- it is used to find the WebElement in web page. It is very useful to identify the dynamic web elements.

Ques 4) What are different types of locators ?

Ans- There are 8 types of locators and all are the static methods of the By class.,, By.tagName(), By.className(), By.linkText(), By.partialLinkText(), By.xpath, By.cssSelector().

Ques 5) What is the difference between Assert and Verify?

Ans- Assert- it is used to verify the result. If the test case fail then it will stop the execution of the test case there itself and move the control to other test case.

Verify- it is also used to verify the result. If the test case fail then it will not stop the execution of that test case.

Ques 6) What is the alternate way to click on login button?

Ans- use submit() method but it can be used only when attribute type=submit.

Ques 7) How do you verify if the checkbox/radio is checked or not ?

Ans- We can use isSelected() method.

Syntax –

driver.findElement(By.xpath("xpath of the checkbox/radio button")).isSelected();

If the return value of this method is true then it is checked else it is not.

Ques 8) How do you handle alert pop-up ?

Ans- To handle alert pop-ups, we need to 1st switch control to alert pop-ups then click on ok or cancle then move control back to main page.


String mainPage = driver.getWindowHandle();

 Alert alt = driver.switchTo().alert(); // to move control to alert popup

 alt.accept(); // to click on ok.

 alt.dismiss(); // to click on cancel.

 //Then move the control back to main web page-

 driver.switchTo().window(mainPage); → to switch back to main page.

Ques 9) How do you launch IE/chrome browser?

Ans- Before launching IE or Chrome browser we need to set the System property.

//To open IE browser

System.setProperty(“”,”path of the iedriver.exe file ”);

 WebDriver driver = new InternetExplorerDriver();
//To open Chrome browser → System.setProperty(“”,”path of the chromeDriver.exe file ”);

 WebDriver driver = new ChromeDriver();

Ques 10) How to perform right click using WebDriver?

Ans- Use Actions class

Actions act = new Actions(driver); // where driver is WebDriver type



Ques 11) How do perform drag and drop using WebDriver?

Ans- Use Action class

Actions act = new Actions(driver);

 WebElement source = driver.findElement(By.xpath(“ -----”)); //source ele which you want to drag

 WebElement target = driver.findElement(By.xpath(“ -----”)); //target where you want to drop


Ques 12) Give the example for method overload in WebDriver.

Ans- frame(string), frame(int), frame(WebElement).

Ques 13) How do you upload a file?

Ans- To upload a file we can use sendKeys() method.

driver.findElement(By.xpath(“input field”)).sendKeys(“path of the file which u want to upload”);

Ques 14) How do you click on a menu item in a drop down menu?

Ans- If that menu has been created by using select tag then we can use the methods selectByValue() or selectByIndex() or selectByVisibleText(). These are the methods of the Select class.

If the menu has not been created by using the select tag then we can simply find the xpath of that element and click on that to select.

findElement() - it used to find the one web element. It return only one WebElement type.

findElements()- it used to find more than one web element. It return List of WebElements.

Ques 19) How do you achieve synchronization in WebDriver ?

Ans- We can use implicit wait.

Syntax- driver.manage().timeouts().implicitlyWait(10,TimeUnit.SECONDS);

Here it will wait for 10sec if while execution driver did not find the element in the page immediately. This code will attach with each and every line of the script automatically. It is not required to write every time. Just write it once after opening the browser.

Ques 20) Write the code for Reading and Writing to Excel through Selenium ?

FileInputStream fis = new FileInputStream(“path of excel file”);

 Workbook wb = WorkbookFactory.create(fis);

 Sheet s = wb.getSheet("sheetName");

 String value = s.getRow(rowNum).getCell(cellNum).getStringCellValue(); // read data

 s.getRow(rowNum).getCell(cellNum).setCellValue("value to be set"); //write data

 FileOutputStream fos = new FileOutputStream(“path of file”);

 wb.write(fos); //save file

Ques 37) How to check if a text is highlighted on the page ?

Ans- To identify weather color for a field is different or not-

String color = driver.findElement(By.xpath("//a[text()='Shop']")).getCssValue("color");

 String backcolor = driver.findElement(By.xpath("//a[text()='Shop']")).getCssValue("background-color");



Here if both color and back color different then that means that element is in different color.
