Introduction to TestNG

Introduction:

TestNG is a testing framework inspired from JUnit and NUnit but introducing some new functionalists that make it more powerful and easier to use.

TestNG is a testing framework designed to simply a broad range of testing needs, from unit testing (testing a class in isolation of the others) to in integration testing (testing entire systems made of several classes, several packages and even several external frameworks, such as application servers)
