3. Explain your framework architecture?

It a lot of process, you can explain each and every process of your framework architecture. You have to explain each component of your project and test plan, Test-Base class.

4. Webdriver is interface or class?

It is Interface. All the methods which are declared in Webdriver interface are implemented by respective driver class.

6. List some methods in webdriver?

Following are the some important methods in webdriver

get() Syntax: get(url)
getCurrentUrl() Syntax: getCurrentUrl()
getTitle() Syntax: getTitle()
findElements() Syntax: findElements(By by)
findElement()
getPageSource()
close()

7. What is Webelement?

Everything that is present on the web page is a WebElement such as text box, button, etc. WebElement represents an HTML element.

Types of webelements

Edit box
Link
Button
Image, image link, an image button
Text area
Checkbox
Radio button
Dropdown list

8. List some methods in webelements?

Top 10 methods in web elements:

clear
click
findElement
findElements
getAttribute
getCssValue
getLocation
getRect
getSize
getTagName
getText

9. What are the locators?

Locators are defined as an address that identifies a web element uniquely within the webpage. It is a command that tells Selenium IDE which GUI elements like – Text Box, Buttons, Check Boxes etc, it needs to operate on.

10. Which locator you prefer?

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

11. How to configure selenium web driver in eclipse?

It’s easy to get up and running with Selenium-WebDriver using Eclipse and the Java bindings on Windows.

Install Java
Install Eclipse
Download the Selenium Java Client Driver
Configure Eclipse IDE with WebDriver.

12. What is an Object repository?

Object Repository is defined by a collection of object and properties with which QTP will be able to recognize the objects and act on it. While testing the records, the objects and properties are captured by default. Without understanding objects and its properties, QTP will NOT be able to play back the scripts.

13. What is difference between assert and verify commands?

Assert	Verify commands
It is Verifies if the specified condition is true and false.	Verifies if the specified condition is true and false.
In case of false condition, the next text case of the suite will be executed.	In case of false condition, the next test step of the same text case will continue.

14. What is a fundamental difference between XPath and css selector?

XPath	css selector
XPath stands for XML Path. It’s a query language that helps identify elements from an XML document.	Most HTML pages are styled using cascading style sheet classes, also known as CSS
Creating in XPath is more flexible than in CSS Selector.	It’s much easier to learn and implement.
XPath allows you to navigate up the DOM when looking for elements to test or scrape.	The CSS selectors identify the various elements in the DOM, and they affect or connect to these parts of the interface.

15. What is a data-driven framework?

Data Driven framework is used to drive test cases and suites from an external data feed. The data feed can be data sheets like xls, xlsx, and csv files.

Developing Data Driven framework in Selenium using POI helps reduce maintenance, improve test coverage thus providing a good return on investment.

24. Overloading vs Overriding?

Overloading	Overriding
Method overloading is performed within class.	Method overriding occurs in two classes that have IS-A (inheritance) relationship.
In this, methods must have same name and different signature.	While in this, methods must have same name and same signature.
Method overloading may or may not require inheritance.	While method overriding always needs inheritance.
