testNG出现noClassDefFound错误

Question

我尝试在eclipse中使用testNG运行下面的程序，得到如下所示的错误：

代码：

package TestNGPackage;

import org.testng.annotations.Test;
import org.testng.annotations.DataProvider;

public class ParameterizedClass {

    @Test(dataProvider = "Database")

  public void UserDetails(String n, String s) {
      System.out.println("ID and names are: "+ n + s);
  }

  @DataProvider
  public Object[][] Database() {
    Object[][] data= new Object[3][2];

    //rows- number of test to be repeated or number of test data set
    // cols- number of parameters in the test data

    //first row
    data[0][0]="Controls team";
    data[0][1]="Vandee";

   //second row
    data[1][0]="Risk team";
    data[1][1]="Raghu";

    //third row
    data[2][0]="Forecast team";
    data[2][1]="Surbhi";

    return data;
  }

}

错误：

虽然提供了类定义，但我还是得到了这个错误。当我使用TestNG运行时，其他程序运行得很好，所以我怀疑jar文件的问题。

Answer 1

如果它在不同的上下文中工作，这意味着您有不同的类路径。

您是否使用maven、gradle或手动添加库？

Answer 2

请下载maven jar并将其添加到testNG文件夹中，如果使用maven，请添加以下依赖项

 <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.9.10</version>
    </dependency>
