How to fix the error org.testng.eclipse.maven.MavenTestNGLaunchConfigurationProvider.getClasspath(Lorg/eclipse/debug/core/ILaunchConfiguration;)

Question

I have written a code which just opens an webpage and validates whether the page's title matches with the expected string or not.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.annotations.Test;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.AfterTest;

public class NewTest {
     public String website = "https://opensource-demo.orangehrmlive.com/";
     WebDriver driver = new ChromeDriver();
  @Test
  public void f() {
      String actual = driver.getTitle();
      String expected = "OrangeHRM";
      Assert.assertEquals(actual, expected);
  }
  @BeforeTest
  public void beforeTest() {
      driver.get(website);
  }

  @AfterTest
  public void afterTest() {
      driver.close();
  }

}

Now while running the code there is popup window stating an internal error { An internal error occurred during: "Launching NewTest". org.testng.eclipse.maven.MavenTestNGLaunchConfigurationProvider.getClasspath(Lorg/eclipse/debug/core/ILaunchConfiguration;)Ljava/util/List; }

Answer 1

This error message...

An internal error occurred during: "Launching NewTest"
org.testng.eclipse.maven.MavenTestNGLaunchConfigurationProvider.getClasspath(Lorg/eclipse/debug/core/ILaunchConfiguration;)Ljava/util/List;

...implies that there was incompatibility between TestNG and Maven related classfiles.

Historically, this error would occur if while installing testng you have kept the checkbox for M2E Maven as checked .

The easiest approach to address this issue would be to reinstall the TestNG ensuring that the checkbox for M2E Maven is kept unchecked .

Answer 2

1. Open eclipse -> Click on Help -> Click on Installation details -> Search for TestNg M2E(optional) -> Select that and click on Uninstall.
2. Restart your eclipse and rerun your testNg file.

Answer 3
