Next, you are extending all of your Classes from the same Lib class. I have a question here, as all the methods are implemented in remotewebdriver class, why cant we directly call methods from remote webdriver class itself??. That is why, in the first code example, we could not create the WebDriver object. This is a very unwieldy design pattern. Eugene S 3

Hi Kavya, There is java concept called Runtime polymorphism which is achieved when you upcast to WebDriver. Because WebDriver is an interface and not a class. Post as a guest Name. XYZ Collage student details. I also faced the same issue when I was creating custom config xml file module.

Below is the sample code I have added in my di. Next post Inheritance In Java: This is a very unwieldy design pattern. It can perform all functions or methods on the Firefox browser as defined in the interface WebDriver. Add a public getDriverInstance method in the class where the wevdriver is created that will just return the driver instance. Next, you are extending all of your Classes from the same Lib class. In order to initialize featOptionthe initialization tries to call driver. Cannot instantiate class TestCases.
Why do you need both the WebDriver and FirefoxDriver classes?
Given that you’re currently launching a new driver for each TestNG test confusingly, in TestNG a “test” is not at all the same thing as a test method, even though test methods are annotated with Testthat may or may not be what you want. Let me know if you get a point here.
Is it the driver for Firefox, Chrome, Internet Explorer?
There are a few problems here. It specifies what fields and methods the class should have but without providing more details. Please log in using one of these methods to post your comment: Having clarified the difference between WebDriver, FirefoxDriver and ChromeDriver, we can finalize the sample project code: So in the above statement, we are actually telling FirefoxDriver class that “hey you can automate the various methods that you want on the Firefox browser but you need to stick to the contract defined in WebDriver”.
If we upcast to RemoteWebDriver its a fully implemented class which has access to all methods that are there even at WebDriver level. Get my posts in your inbox. Give any name to Interface Example: So, we can replace the WebDriver type with another type, for example, FirefoxDriver. Post was not instantiwte – check your email addresses!
