I\'m able to run TestNG unit tests in IntelliJ and see the pass/fail output in a window; this is without using any testng.xml file. I can also run the tests in
1.Go to Intellij>Preferences>Plugins>Verify that TestNG-J is enabled.
2.Configure the testNG xml file and provide it as an external source by going to edit configurations and selecting suite and providing the path of the testNG xml you created.
