![]() In the next blog post, I’ll dive deeper into the second of the four fundamental principles of object-oriented programming: inheritance. All this makes for a clean API for the page object class and better separation of concerns. The ‘user’ of such a Page Object class (typically a test method) can then interact with the elements defined in the class only through a public method, without having direct access to (and without the need to concern itself with) the page implementation details, such as the HTML structure and any synchronization with the state of the elements. Just to be clear I don't want to copy a text from screen like this: driver.findelement (by.xpath).sendKeys (Keys. Can somebody helps me of any questions in stack overflow would be very helpful. But I just couldn't find the right way to do it.

A very naive implementation of this class might look something like this: public class Account String text 'test' I want to paste the string text using selenium Keys.CONTROL+'v'. To illustrate the concept of encapsulation and its importance, let’s consider a class Account that represents a bank account, with two properties: the account type (modeled using an enum AccountType that can take the values CHECKING and SAVINGS) and the account balance, modeled as a double. Encapsulation is generally applied to prevent outside users from directly accessing and modifying properties of an object, often for reasons of security or to prevent corruption of data. What is encapsulation?Įncapsulation is the practice of hiding implementation details, or the inner state, of an object and selectively exposing access to these internals through public methods. We can create functions or reference variables that behave differently in a different programmatic context. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object. The examples I give will be mostly written in Java, but throughout these blog posts, I’ll mention how to implement these concepts, where possible, in C# and Python, too. Polymorphism is the ability of an object to take on many forms. Understanding these principles helps you better understand application code, make recommendations on how to improve the structure of that code and, of course, write better automation code, too. For Working on Selenium WebDriver with Java, you can focus on below Java concept and other related stuff, I am just giving you bigger picture. Learn Selenium WebDriver, TestNG, Maven, GitHub & Third Party Reporting. Why? Because I think they are essential knowledge not just for developers, but definitely also for testers working with, reading or writing code. Learn Java, OOPS concepts and Selenium programming from scratch by industry expert.
