Question 25:

What are the different types of waits available in WebDriver?

Selenium WebDriver provides the two types of wait:

  1. Implicit Wait
  2. Explicit Wait

Implicit Wait: Implicit provides the facility to poll the DOM for a certain amount of time when trying to find the element if they are not immediatlely. Default time setting is 0.


WebDriver driver = new FirefoxDriver();

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


WebElement element = driver.findElement("Element_Id"));

Explicit Wait: An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. The worst case of this is time.sleep(), which sets the condition to an exact time period to wait.


WebDriver driver = new FirefoxDriver();
WebElement myDynamicElement = (new WebDriverWait(driver, 10)).until(ExpectedConditions.presenceOfElementLocated("myDynamicElement")));

Question 26:

What is difference between driver.close() and driver.quit()?


It is used to close the browser or page currently which is having the focus.


It is used to shut down the web driver instance or destroy the web driver instance means close all the browser windows. Basically it calls the driver.dispose method which in turn close s all the browser windows and ends the web driver session gracefully.

Question 27:

What is the TextNG?

TextNG is a testing framework for Java programing language and designed to simplify a broad range of testing needs, from unit testing to integration testing(testing entire system made of several classes and packages). In other words, TextNG is designed to cover all categories of testing like unit, end-to-end, functional, integration etc. where NG means Next Generation.  It is an open source framework and inspired by JUnit. It is similar to Junit and designed to be better than Junit.
