9. How you are handling keyword driven and data-driven framework in your project?

Keyword driven framework : The Keyword-Driven framework is a technique to externalize keywords or actions that are used in the script in a separate Object Repository which will give positive outcomes like increased code-reusability, reduced script maintenance, and higher portability.

Data driven framework : Data Driven framework is focused on separating the test scripts logic and the test data from each other. Allows us to create test automation scripts by passing different sets of test data.

10. What is mean by hybrid framework?

Data-Driven and Keyword Driven frameworks both are mixed in hybrid frameworks. It is used in increased code reusability, higher portability, reduced cost of script maintenance, better code readability, etc.,

11. How can you upload file in webpage?

12. How you will handle popup in web driver?

You need to use below code,

String parentWindowHandler = driver.getWindowHandle(); // Store your parent window String subWindowHandler = null; Set<String> handles = driver.getWindowHandles(); // get all window handles Iterator<String> iterator = handles.iterator(); while (iterator.hasNext()){ subWindowHandler = iterator.next(); } driver.switchTo().window(subWindowHandler); // switch to popup window // Now you are in the popup window, perform necessary actions here driver.switchTo().window(parentWindowHandler);

13. What framework your are using?

Types of frameworks

Data Driven Automation Framework
Method Driven Automation Framework
Modular Automation Framework
Keyword Driven Automation Framework
Hybrid Automation Framework

You can explain which one you used in your project.

14. How can you handle pagination in Selenium Webdriver?

To Get the pagination size.
Check whether the pagination exist or not.
If pagination exist, make a loop and click until last pagination size.

15. What is Selenium Grid?

Selenium Grid is the one of the important feature in selenium. I can allows to run multiple use cases in multiple machines. Your local machine is running multiple applications, so you want to run your test cases in a remote machine. You need to configure the remote server so that the test cases can be executed there.

16. What are all locators?

Types of locators:

By CSS ID: find_element_by_id
By CSS class name: find_element_by_class_name
By name attribute: find_element_by_name
By DOM structure or xpath: find_element_by_xpath
By link text: find_element_by_link_text
By partial link text: find_element_by_partial_link_text
By HTML tag name: find_element_by_tag_name

17. Difference between findelements and findelement

findelements	findelement
It returns all the web elements which match with the locator.	For matching with the locators, it returns the first web element
if there are no matching web elements then returned NoSuchElementException	if there are no matching web elements then returned empty list.
Find element by XPath will only find one web element	It will find a collection of elements whose match the locator strategy.

18. How to handle Popup window?

The below two methods are used to handle popup window,

Driver. getWindowHandles() Driver. getWindowHandle()

19. How to handle alert?

The following methods are useful to handle alerts in selenium:

driver.switchTo().alert().dismiss(); – Cancel button clicked in alert box driver.switchTo().alert().accept(); – OK button alert driver.switchTo().alert().getText(); – Capture the alert message driver.switchTo().alert().sendKeys(“Text”); – Send data to the alert box

Final thoughts of deliverables and milestones

24. How you are using Testng with Webdriver?

To Create a new Java project in Eclipse to write your TestNG test case
Add the library to your Java project
Create packages for your project
Write test case script
Run the TestNG test case
Run the execution

25. Difference in Testnng over Junit

TestNG	Junit
TestNG can run parallel tests.	JUnit does not support to run parallel tests.
In TestNG Dependency tests are present	In Junit dependency tests are missed
TestNG can run parallel tests.	not support to run parallel tests.

26. Draw the architecture diagram of your selenium Framework of your project

27. Waterfall model

Waterfall model is a sequential model that divides software development into predefined phases. Also each phase must be completed before the next phase can begin with no overlap between the any phases. This model in every phase is designed for performing specific activity during the Software development life cycle phase.

28. Defect life cycle

Defect life cycle, also called as Bug Life cycle is the journey of a defect cycle, which a defect goes through during its lifetime. It is different from company to company and also every project. It can be varies from software testing process and also depends upon the tools used.

29. SDLC life cycle

Software Development Life Cycle is known as SDLC, it is used to produce high-quality software that meets customer expectations. SDLC have a detailed planof your project which explains how to plan, build, and maintain specific application. > It is the important part of project tracking and controlling.
