You can use the dataProviderClass attribute of @Test:

public class StaticProvider {
  @DataProvider(name = "create")
  public static Object[][] createData() {
    return new Object[][] {
      new Object[] { new Integer(42) }
    };
  }
}

public class MyTest {
  @Test(dataProvider = "create", dataProviderClass = StaticProvider.class)
  public void test(Integer n) {
    // ...
  }
}

Check the documentation for more details.

The only thing worth extra mentioning is that: "If you want to put your data provider in a different class, it needs to be a static method or a class with a non-arg constructor(...)", so it does not have to be static. – Grzegorz Górkiewicz May 01 '17 at 08:06
@juherr: what happens if there are more than one dataproviders in the same class? – Kushal Bhalaik May 02 '17 at 07:16
I suppose in your answer you mean `dataProvider = "createData"` – Kushal Bhalaik May 02 '17 at 07:17
A data provider is defined by its name. Here, "create". – juherr May 02 '17 at 18:32
@kushal - Not required. It can be "create" alone – smilyface Mar 21 '18 at 09:44

If you have unique dataProvider method name (createData), and if you choose not to give name after DataProvider annotation as below,

@DataProvider    
public Object[][] createData(){

}

Then you can use the method name as below,

@Test(dataProvider = "createData", dataProviderClass = StaticProvider.class)
