Error: Could not find or load main class org.testng.remote.RemoteTestNG

Question

I have written a test suite using TestNG. I have included only one test.java file for my service. I have created the testng.xml file as well. When I run the testng.xml file, I'm getting below error:

 Error: Could not find or load main class org.testng.remote.RemoteTestNG

Please let me know how to fix this. Created the test suite using this link. I ran the suite using this link.

Edits: My testng.xml looks like:

<suite name="TestAll">
  <test name="testService">
    <classes>
       <class name="com.ui.business.service.impl.myservice.test.MyServiceTest"/>
   </classes>
 </test>
 </suite>

I have kept the testng.xml in the root folder. The project compiles with Maven. My service class is in com.ui.business.service.impl.myservice package. When I run the testng.xml with "TestNG Suite", I get this error. Please suggest what to do for resolving this classpath issue.

Answer 1

This worked for me:

• Right click on your project
• Click on Properties
• Click on TestNG
• Uncheck Use Project TestNG jar box
• Click on Apply and Close

Answer 2

I saw this problem when I run testNG in eclipse. I found that it's because the testng jar I included in my build was upgraded from 6.9.9 to 6.9.11. In testng 6.9.11 the class RemoteTestNG is gone. I upgraded by eclipse testng plugin from 6.9.9 to 6.9.11 and the problem is gone.
