Ness Digital Engineering Interview Questions, Process, and Tips

Page Object Model is a design pattern used in test automation to create an object repository for web UI elements.

• It helps in reducing code duplication and improves code maintainability.

• Each web page is represented as a separate class and the web elements on the page are defined as variables in the class.

• The methods in the class perform actions on the web elements.

• It separates the test logic from the page-specific logic...read more

Main function in Java is the entry point of any Java program.

• Relative XPath starts from the current node and selects the nodes based on the p

Polymorphism is the ability of an object to take on many forms. There are two types: compile-time and runtime.

• Compile-time polymorphism is achieved through function overloading and operator overloading.

• Runtime polymorphism is achieved through virtual functions and function overriding.

• Polymorphism allows for code reusability and flexibility in object-oriented programming.

• Example of compile-time polymorphism: function ov...read more

An interface is a contract between two entities defining the communication between them. In Selenium, interfaces are used to define the behavior of web elements.

• An interface defines a set of methods that a class implementing it must implement

• In Selenium, the WebElement interface is used to interact with web elements on a page

• Other interfaces in Selenium include WebDriver, TakesScreenshot, and JavascriptExecutor

Yes, I am familiar with API testing.

• API testing involves testing the functionality, reliability, performance, and security of APIs.

• It includes verifying the response data, status codes, headers, and error handling.

• Tools like Postman, SoapUI, or cURL can be used for API testing.

• Examples of API testing include testing RESTful APIs, web services, and microservices.

• Test cases can be created to validate input/output, authen
