When we try to run TestNG tests, we get the following exception. Unable to initialize main class org.testng.remote.RemoteTestNG
Error Trace
Error: Unable to initialize main class
org.testng.remote.RemoteTestNG
Caused by: java.lang.NoClassDefFoundError: org/testng/TestNGException
Root cause
TestNG library is not found in the classpath. The fix for the error depends on the environment on how the tests are run. If the error occurs while running tests in Eclipse IDE, add the TestNG library to the project build path.
Right-click on the Package explorer choose, Build Path >> Configure Build Path…
In the Java Build Path screen, Select the Libraries tab, click on the Add Library… button.
Choose TestNG and click on the Next button.
Click on the Finish button and Apply the action to save the setting.
This will add the TestNG to the project. Run the TestNG tests. This will solve the exception and tests would run successfully.
