Answer 1

You have to edit your testng.xml file. See this example:

<test name="Smoke Test"> 
<classes>
 <class name="packagename.classname"> </class>
 </classes>
 </test>

In , you must enter your tests package name before name of class that you want to run.

Please go through the below link and you can ask query here.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=558495 

The above link didn't work it means you need a higher version of TestNG for the eclipse. Before that check TestNG is installed or not in order to know that press CTRL+N in the wizard you can see TestNG class file name.

If it is not displaying then try installing TestNG In Eclipse IDE Via Offline Jar Files:

1)Download the latest TestNG Jar files from the link TestNg Jars ("https://github.com/cbeust/testng-eclipse") 2)Download TestNG 6.11, Clicking on the link will download the “site_assembly.zip” file for the TestNG version 6.11. This file contains two folders named as “features” and “plugins“.Go to the eclipse installation directory and look for the “dropins” folder there. 3)Create a folder inside the dropins folder and name it as “testng-eclipse-6.11“ 4)Extract the “site_assembly.zip” file and copy its contents to the newly created “testng-eclipse-6.11” directory. 5)Restart Eclipse

OR

Go click on Help> Install new Software> Under Available software> Work with textbox paste this "2019-06 - http://download.eclipse.org/releases/2019-06" and then click on ADD. You will now see the files like TestNG and a lot of many others. Select TestNG click on Next> Next> Accept the condtions> Finish. It will restart the eclipse. Inorder to know the installation is successful Press CTRL+N.
