TestNG 5.0 Smoothes Out Annotations


Test tool update reduces confusion when running thousands of tests

By Alex Handy
August 15, 2006 — 
TestNG’s ability to organize thousands of unit tests has improved with the release of version 5.0 in late July.

C?dric Beust, a software engineer at Google, explained that he began developing TestNG three years ago because he believed JUnit was too limited in scope for proper enterprise use. Beust acknowledged that JUnit is the more popular unit testing tool for Java, but that his own TestNG offers better options for handling large numbers of tests.

“The major feature [in this release] is not brand-new; it’s about more renaming and cleanup of annotation names to make them more intuitive. Our reports are easier to read and better organized now. As we have more and more users who have thousands of tests and dozens of groups, it becomes really important to make those reports easy to read,” said Beust, who is originally from France.

But despite being open-source, the project has remained primarily a two-man affair. Most of the third-party work has been done on making TestNG work with IDEs such as Eclipse, NetBeans and IntelliJ IDEA. But outside of those contributions, most of the work on the project has been done exclusively by Beust and Alexandru Popescu, who began contributing code soon after Beust created TestNG.

For the future, Beust would like to see more contributors to the TestNG project, but doesn’t expect many changes to its core functionality. “For the past year, there were less features requested in the core, and we were working on productivity around the core, which is good because it means the core is working and functional enough,” said Beust of the 600-strong mailing list for the tool.

“I think we’re going to see stronger integration with Web servers so we can drive TestNG from remote machines,” Beust added, saying that he’s also creating a version that can handle distributed tests. “The general message is going to be more about scaling. For people writing thousands of tests, we want to make it almost transparent for them to use as many machines and as much power as they have.”

Despite Beust’s employment at Google, the tool has little to do with the company. TestNG is a free and open-source tool. It can be downloaded at www.testng.org.
