Go to mvnrepository.com and search for testng .

In the "Files" row, click on the jar link to start the download.

The most efficient way to use TestNG with Maven is to add a dependency to your pom.xml file. This allows Maven to automatically download the JAR and its required transitive dependencies (like JCommander).

org.testng testng 7.12.0 test Use code with caution. JDK 11 and above: Use version 7.9.0 or later. JDK 8: Use version 7.5.1 for maximum compatibility. 3. Configuring Maven to Run TestNG Tests

org.apache.maven.plugins maven-surefire-plugin 3.5.5 testng.xml Use code with caution.

If you are not using a build tool and need the raw .jar file, you can download it directly from the Maven Repository .
