And these will implement the abstract methods of WebDriver interface in their way. That’s where you have separate class files for FirefoxDriver, ChromeDriver etc. So if I write an Interface with abstract methods I can send a message to all the browser companies i.e the third party companies to provide their implementation classes for my Interface. Even though I am successful in writing the code for all the browsers, by the time I release it to the market a new version of the same browser will come rendering all my efforts futile So if I want to write WebDriver code to work with Firefox then I will write code for Firefox, similarly I will have to write many class files for all the browsers. In almost all the tutorials, we give working examples of real problems. Time to time, we also post advanced Selenium Webdriver tutorials on this blog. We need to remember one thing, Selenium WebDriver’s architecture is designed in a way that it talks to browser in its native language. of Selenium Webdriver tutorials covering the basics of Selenium Webdriver, Selenium RC, Selenium IDE, and Selenium Webdriver commands. Is it a waste of time? Its better to write classes for different browsers isn’t it? Obvious question is then why do we need an Interface which does not have any method body. The classes which implement the abstract methods of interface are known as implementation classes. So we cant create an object to interface but we can create classes where we can implement the abstract methods of the interface. This is how it lookedĪn Interface which looks like a class will contain Abstract methods (body less methods). So we downloaded the Selenium jar file and decompiled it to see all the class files. One of the useful points about open source software like Selenium is that we can see the source code. Rather the syntax WebDriver driver = new FirefoxDriver() is an syntax of an interface. Since Java is based on Oops(Object oriented programming) concept we can clearly say that we have not created an object of WebDriver class. We never write WebDriver driver = new WebDriver() 6- String class, Wrapper classes, Array (2 D arrays) 7- Exception handling. WebDriver driver = new FirefoxDriver() or WebDriver driver = new ChromeDriver() 1- OOPS Concept You should know the basic concept of Oops like Class, Object, Inheritance, Polymorphism, Abstraction 2- List of keywords, Interface in Java. Tutorial designed for complete beginners in Selenium testing and automation 4. So if we want to launch a Firefox browser we will write the following syntax in Java Selenium WebDriver with Java for beginners Selenium WebDriver with Java and TestNG. Obviously we need to understand the difference between what is a class and how is it different than an interface.įor all Selenium users if they reckon The initial block of code involves telling Selenium which browser it should launch. In our free Java bootcamp (part of #testerbhicoder initiative) while we talk about interface, an often asked query is about what exactly is Selenium WebDriver. The Selenium – Java combination is the most popular among automation testers. This article was first published in Agile Testing Alliance BlogĪs many of you know Selenium is the most popular open source tool for automating web applications.
