What is polymorphism real time example in selenium?

Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. We can create functions or reference variables that behave differently in a different programmatic context.

What is an abstract class and have you used it in your Selenium project?

When superclass just defines the structure of the methods without providing complete implementation of every method and the subclass overrides the abstract methods in superclass and implements them, then the superclass is called as abstract class.

What is real time example of abstract class?

That has a plethora of benefits, such as reducing bugs and making coding faster. A concrete example of an abstract class would be a class called Animal. You see many animals in real life, but there are only kinds of animals.

Where we can use abstract class in selenium?

Example of Abstract vs Concrete Class: If you have complete requirements then you will go for a concrete class, but if you have a partial requirements in hand then you can go for Abstract Class. Use this class as base class, if you want to implement a WebDriverEventListener and are only interested in some events.

Where you have used polymorphism in your project?

The reason why you use polymorphism is when you build generic frameworks that take a whole bunch of different objects with the same interface. When you create a new type of object, you don’t need to change the framework to accommodate the new object type, as long as it follows the “rules” of the object.

Why do we need abstract class in selenium?

If you do know something but still need help of others, use an Abstract class. “. Usage of Interfaces and Abstract classes is needed for better architectural design for better scalability, maintainability and less painful to make a bigger change.

Where did you use abstract class in your project?

When we have the requirement of a class that contains some common properties or methods with some common properties whose implementation is different for different classes, in that situation, it’s better to use Abstract Class then Interface.

What is an abstract class and why do we use it?

The short answer: An abstract class allows you to create functionality that subclasses can implement or override. An interface only allows you to define functionality, not implement it. And whereas a class can extend only one abstract class, it can take advantage of multiple interfaces.

What is abstraction and give a real life example?

Abstraction means displaying only essential information and hiding the details. Data abstraction refers to providing only essential information about the data to the outside world, hiding the background details or implementation. Consider a real life example of a man driving a car.

Why are abstract classes needed over interface explained with real life example?

Abstract classes provide you the flexibility to have certain concrete methods and some other methods that the derived classes should implement. On the other hand, if you use interfaces, you would need to implement all the methods in the class that extends the interface.

Is WebDriver abstract class?

Because here WebDriver (JavaDocs)is an interface and all the methods implemented in FirefoxDriver and ChromeDriver . Selenium’s AbstractWebDriverEventListener is an abstract class, where we can implement definition for only required methods.

What is polymorphism example?

A real-life example of polymorphism, a person at the same time can have different characteristics. Like a man at the same time is a father, a husband, an employee. So the same person posses different behavior in different situations. This is called polymorphism.

What is polymorphism in selenium Java?

Polymorphism in Java/selenium Polymorphism is the ability of an object to take on many forms.

We can create functions or reference variables that behave differently in a different programmatic context.

What is the use of abstract class in selenium?

Abstract class plays a major role in framework. All the reusable methods that you will use across all page classes are written in this abstract class say Reusable library and reusable methods for click, sendkeys, fetchTooltip etc. Where you have used interface in your selenium project?

What is the difference between abstract class and polymorphism?

This is how we use Abstract class in real projects. Just to cite an example in Selenium itself; By class is an abstract class. Polymorphism is of types – Overloading and Overriding. One example where Overloading can be used is in Logger design.

What is an example of polymorphism in testing?

Example of Polymorphism: There would be a common access class which have the framwork object access and all testcase class have to inherit (extent) it and make use of test framework objects in their own testcase class.
