java - TestNG dataproviders with a @BeforeClass -

i trying run class multiple tests under 2 different conditions. have bunch of tests related search. adding new functionality of new search strategy, , in meantime want run written tests under both configurations. have multiple classes each multiple tests want streamline process as possible. ideally it'd great setup in @beforeclass data provider tests in class run twice under different configurations, doesn't possible.

right have:

public class searchtest1 {     @test(dataprovider = "searchtype")     public void test1(searchtype searchtype) {         setsearchtype(searchtype);         //do test1 logic     }      @test(dataprovider = "searchtype")     public void test2(searchtype searchtype) {         setsearchtype(searchtype);         //do test2 logic     }      @dataprovider(name = "searchtype")     public object[][] createdata() {         return new object[][]{             new object[] {searchtype.scheme1, searchtype.scheme2}         }     } } 

is there better way this?

if want avoid having annotate each , every method data provider, can use factory instead.

public class searchtest1 {     private final searchtype searchtype;      public searchtest1( searchtype searchtype ) {        this.searchtype = searchtype;     }      @test     public void test2() {         //do test2 logic     }     ... } 

and factory class be:

public class searchtestfactory {    @factory    public object [] createinstances() {       return new object[] { new seartchtest1( searchtype.one ), new searchtest1( searchtype.two ) };    } } 

see more on here.

then can either have 1 factory enumerates every test class or separate factory each, first 1 less flexible, second 1 means more code.
