org.testng.TestNGException Cannot find class in classpath

Question

I have a maven project where the following classes are present:

src/main/java/App.java

src/test/java/AppTest.java

The testng.xml is under the project root. I want to trigger tests from the App.java main method using the testng.xml:

public static void main(String[] args) {
        TestNG testng = new TestNG();
        List<String> suites = Lists.newArrayList();
        suites.add("testng.xml");
        testng.setTestSuites(suites);
        testng.run();
    }

Maven project is built still I am getting errors:

Exception in thread "main" org.testng.TestNGException: Cannot find class in classpath.

Quite similar to https://stackoverflow.com/questions/16465695/how-to-run-testng-tests-from-main-in-an-executable-jar — Saikat, Dec 20 '18 at 09:20

You can't execute java files from below main folder using testNG xml file.

src/main/java

You should include all your test files in

src/test/java

Then you can give the class name in testNG.xml file which is present in test folder. Then you would not get above error.

My test class is under src/test/java – Saikat Dec 20 '18 at 09:03
@Saikat You should trigger tests from AppTest.java, not from App.java as you have told in question – Chintamani Manjare Dec 20 '18 at 09:04
The test is in AppTest.java, I am trying to call it from main method, so that an executable jar can be used to run the tests. – Saikat Dec 20 '18 at 09:19

1) Steps to trace issues:

Create demo Test with following syntax and check execution:

class demo{    
  @Test
  public void testDemo(){
  System.out.println("Hello World");
  }     
}

If this has been work successfully, You have problem in your Test build structure.
