TestNG

Features

TestNG features include:

• Flexible test configuration.
• Support for data-driven testing (with @DataProvider).
• Support for multiple instances of the same test class (with @Factory)
• Support for parameters.
• Allows distribution of tests on slave machines.
• Powerful execution model (no more TestSuite).
• Embeds BeanShell for further flexibility.
• Default JDK functions for runtime and logging (no dependencies).
• Dependent methods for application server testing.

Tool Support

TestNG is supported, out-of-the-box or via plug-ins, by each of the three major Java IDEs - Eclipse, IntelliJ IDEA, and NetBeans. It also comes with a custom task for Apache Ant and is supported by the Maven build system. The Hudson continuous integration server has built-in support for TestNG and is able to track and chart test results over time. Most Java code coverage tools, such as Cobertura, work seamlessly with TestNG.

Reporting

TestNG generates test reports in HTML and XML formats. The XML output can be transformed by the Ant JUnitReport task to generate reports similar to those obtained when using JUnit. Since version 4.6, TestNG also provides a reporter API that permits third-party report generators, such as ReportNG and TestNG-XSLT, to be used.
