Testing as you may know is the process of validating and verifying that a piece of software or hardware is working according to the way it’s expected to work.
Test automation, as the name suggests, refers to automating the testing process.
Test automation gives an advantage of running tests in numerous ways such as at regular intervals or as part of the application build.
This helps in identifying bugs at the initial phase of development itself, hence reducing the product timeline and improving the product quality.
It also helps in reducing the repetitive manual testing effort and allows manual testing teams to focus on testing new features and complex scenarios.
Test NG, where NG stands for “next generation” is a test automation framework inspired by JUnit (in Java) and NUnit (in C#).
It can be used for unit, functional, integration, and end-to-end testing.
Test NG has gained a lot of popularity within a short time and is one of the most widely used testing frameworks among Java developers.
It mainly uses Java annotations to configure and write test methods.
A few of the features that Test NG has over JUnit 4 are: It is written in Java and can be used with Java as well as with Java-related languages such as Groovy.
