- 12. www.edureka.co/testing-with-selenium-webdriverEDUREKA’S SELENIUM CERTIFICATION TRAINING What Is TestNG? TestNG is an open source testing framework inspired by JUnit. It stands for Test Next Generation TestNG is more flexible & powerful than JUnit because of below functionalities: T e s t S c r i p t s T E S T R E P O R T S Prioritization Method Dependency Parallel Testing Assertions Disabling Test Cases GroupingAnnotations Report Generation
- 13. www.edureka.co/testing-with-selenium-webdriverEDUREKA’S SELENIUM CERTIFICATION TRAINING Advantages Of Using TestNG • HTML reports can be generated • Supports parallel testing • Test cases can be grouped & prioritized easily • Uses annotations for executing methods • Supports parameterization Note: Java is a pre-requisite for TestNG 1. Write the business logic of the test and insert TestNG annotations in the code 2. Add the information about your test (e.g. the class names, methods names, groups names etc.) in a testng.xml file or build.xml file 3. Run TestNG Steps for writing TestNG tests Advantages of using TestNG
- 14. www.edureka.co/testing-with-selenium-webdriverEDUREKA’S SELENIUM CERTIFICATION TRAINING Annotations In TestNG Annotations in TestNG are used to control the next method to be executed in the program TestNG programs will not have ‘main’ method. However, all methods will be annotated with ‘@’ Test methods – Primary methods to be executed Will be executed before both test method Will be executed after both test method A n n o t a t i o n s P r i o r i t i z a t i o n R e p o r t G e n e ra t i o n P a r a l l e l Te s t i n g A s s e r t i o n sG r o u p i n g M e t h o d D e p e n d e n c y D i s a b l i n g Te s t C a s e s

Add the following code to the said file This xml file contains only one test inside a suite. This contains the groups section defined by using the groups tag as shown in the code. The run tag represents the group that needs to be run. The include tag represents the name of the group that needs to be executed.

Radha Muthian says, “I learned Selenium WebDriver and the course was very helpful to automate the Web Applications. The lifetime access of classes helps a lot to refer back and download the codes.” Vijay Krishnan says, “I have attended Selenium Web driver Certification with Edureka. The trainer has explained all the concepts of the course in detail manner which was very easy to understand. Worth for the money spent!!!!” Tom Tully says, “I wanted to learn Selenium Webdriver in a live, real course, not self paced, so there would be pressure on me to finish. Edureka accomplished this at a price far lower than an in-person class, and as far as I know they are the only internet class that has live lectures on this subject. Teacher was very knowledgeable. I learned basic use of Selenium. No problem with me being in US and teacher in India. They have US 800 number.” Suhas Kashyap says, “The online Course(Selenium Webdriver), which I took from Edureka was interactive and also helped me to improve my knowledge on selenium. Further helped me in changing the job as well. Thanks Edureka Team... :).”
