11.What is the difference between WebDriver and RemoteWebDriver in Selenium?
- Remote Web Driver requires the selenium-server-standalone to be running (the others do not). This could be running on the same machine or a “remote” one.
- If we want to use the browser on the machine that is running the automation, then we can use everything but RemoteWebDriver.
- The major difference is that RemoteWebDriver sends that request to open and control a web browser to a server, so you normally wouldn’t see the browser open and do it’s thing.
- If we are using Selenium Grid then it is mandatory to use Selenium Webdriver.
12.What are the best practices for maintaining the testing framework using Selenium webdriver using Java?
- Using page object model with PageFactory : In page Object model we create an class of each page of our application. The goal is to encapsulate the functions of each page in a page object, and to use these objects in the test our Test scripts.
- Keeping test scripts separate from Java implementation code : Keep it in a separate directory for clarity. Test scripts should be readable by a product manager or other non-programmer. It’s a good practice to keep test scripts separate and creating packages module wise. If they are getting unmanageable, consider them refactoring.
- Use Maven for managing jar dependencies : Maven is very good build management tool and you can easily manage you dependencies from POM.xml
- Use TestNG instead of Junit : In TestNG you get lots of options such as grouping test cases Assertions , Paraller execution , You can easily execute group of test cases with help of TestNG.xml file.
- Use drivers instantiation such as new FireFoxDriver, new ChromeDriver in Before Annotations: As your script use @BeforeClass or @BeforeTest or any other @Before annotation of create an instance of your browser. To avoid the repetition of this code as it is very basic and needed scipt will be get used everywhere.
- Using Good Reporting tool – You can keep you managers and stack holders happy with beautiful reports such as extent reports like Allure Reports , ReportNG and these will collate your results into something readable and Presentable.
- If possible Use Jenkins : May be you are at early stage of your Automation framework development and environment is not stable yet but whenever possible use Jenkins for scheduling jobs and sending mails in case of build failure.
