Is TestNG better than JUnit?
The debate of whether to use TestNG vs. JUnit has been going on for a long time, and new technologies tend to lead to further questions about which one is better.
JUnit is an open source framework that allows its users to create test cases in Java. It’s the standard testing framework for Java, and it’s been around since 2000. TestNG is a newer testing framework that was created in 2005. The main difference between the two is that JUnit runs tests sequentially while TestNG allows them to run in parallel. This means that TestNG can run tests much faster because they are executing at the same time as each other, whereas JUnit runs tests one by one (which can be very slow when there are hundreds of different tests).
TestNG actually has more features than JUnit. Some of those features include:
-
A nicer test report with XML output
-
An ability to write test cases in multiple programming languages
-
An ability to set up test data using annotations
-
An ability to integrate with every available mock object framework
