Data Provider in TestNG gives a class not found exception

M

Posted on 04/08/2016

I am using the same code as in the tutorials, I have a sample script for data providers as below :

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

public class Sample_data_provider {

public class DP {

@Test(dataProvider = "DPER")
public void some1(String b) {
System.out.println("check"+b);
}

@DataProvider
public String DPER() {
String a = "ABCD" ;
return a ;
}
}

}

The above code gives class not found exception. However, when I checked on internet, I found that I need to use attribute @Guice on my public class. However, when I use it, I get error as The type com.google.inject.Module cannot be resolved. It is indirectly referenced from required .class files.

Below is my current code ,

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

public class Sample_data_provider {

@Guice
public class DP {

@Test(dataProvider = "DPER")
public void some1(String b) {
System.out.println("dvjdns"+b);
}

@DataProvider
public String DPER() {
String a = "ABCD" ;
return a ;
}
}

}

Please help to get my data providers fixed.
