![]() Otherwise the PageObject class will end up with hundreds of object methods. Exposure to Selenium WebDriver using Java and C. So the point is it is not useful to create object methods till the time test makes use of it. Good with Java 8 features and OOPS concepts with realtime examples. The test call the LoginToApplication() method to do the thing. The reason is, so far in the LogInTest, we have not used Username & Password directly. Although all the properties have been changed to private now. Notice that in above LogInPage class, we have not created any Accessor or Mutator for Username & Password field. With the above assumption in our Framework, we should make all the Page Objects as Private. A class can change the data type of a field and users of the class do not need to change any of their code. The users of a class do not know how the class stores its data. /rebates/2fcourse2fjava-oops-concepts-in-selenium-automation-framework2f&.A class can have total control over what is stored in it's fields.The fields of a class can be made read-only or write-only.Mutators are commonly another portion of the property discussed above, except this time it's the set method that lets the caller modify the member data behind the scenes. Mutators are public methods that are used to modify the state of an object, while hiding the implementation of exactly how the data gets modified. In OOP, these are usually in the form of properties, which have, under normal conditions, a get method, which is an accessor method. However, accessor methods are not restricted to properties and can be any public method that gives information about the state of the object. Provide public setter and getter methods to modify and view the variables values.Īn accessor is a method that is used to ask an object about itself.Declare the variables of a class as private.In encapsulation the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class, therefore it is also known as data hiding. Encapsulation - OOPs PrincipleĮncapsulation in Java is a mechanism of wrapping the data ( variables) and code acting on the data ( methods) together as a single unit. It helps to make the code more secure, readable and maintainable. It very is necessary for us to implement the same principle in the Test Framework as well. In terms of Selenium with Java, it’s ideal for you to learn the Java topics which are necessary to write better Selenium Scripts. I don’t say there is no need to learn complete Java. ![]() Before jumping into the details of this chapter of Encapsulate Selenium Page Objects, let's just understand what is the most important Object Oriented Programming Principle. Selenium with Java is widely used and preferred language by automation testers compared to other languages.
