What are TestNG and JUnit frameworks in Selenium

Question

I have started learning selenium through YouTube videos and online tutorial..

I now have knowledge on Creating Classes, Interfaces, Objects, Inheritance, Arrays, Loops in Java.

As far as Selenium is concerned, I am able automate directly in Selenium using Java language by identifying each elements using Firebug/Firepath tool.

But I constantly hear about TestNG and JUnit frameworks...

1. What are these?
2. How are they related to selenium?
3. Is it difficult to pick them up with the amount of knowledge I currently possess?

Answer 1

1. They are tools to help you organize your tests. You can define what you want to run before/after tests, you can group your tests, and reporting on them is made easier.

2. It is usually mentioned with Selenium because Selenium is a common testing tool. The two work together well, but they are completely separate. (Selenium connects you to your browser, TestNG/JUnit organizes the tests)

3. Yes. You should be able to pick them up. They are designed to be fairly easy to learn.

Answer 2

JUnit is shipped with most of the IDEs such as Eclipse and NetBeans. There are many testing frameworks being developed using JUnit.

TestNG is an open source framework. It supports parametrization, data driven testing, parallel execution. JUnit is not much flexible for these.

I prefer TestNG over JUnit. I have developed open source testing framework using TestNG for Selenium. You may want to have a look at it.
