TestNG Interview Questions and Answers

TestNG is a testing framework for the Java programming language created by Cédric Beust and inspired by JUnit and NUnit. The design goal of TestNG is to cover a wider range of test categories: unit, functional, end-to-end, integration, etc., with more powerful and easy-to-use functionalities. It is an open source automated testing framework; where NG of TestNG means Next Generation. TestNG is similar to JUnit but it is much more powerful than JUnit but still it’s inspired by JUnit. It is designed to be better than JUnit, especially when testing integrated classes. .
TestNG is a testing framework designed to simplify a broad range of testing needs, from unit testing (testing a class in isolation of the others) to integration testing (testing entire systems made of several classes, several packages and even several external frameworks, such as application servers).
Writing a test is typically a three-step process:
Write the business logic of your test and insert TestNG annotations in your code.
Add the information about your test (e.g. the class name, the groups you wish to run, etc…) in a testng.xml file or in build.xml.
Run TestNG.
