TestNG run set of test cases in loop

Searched everywhere but could not find solution how to do following: As Example:

 for (int i = 0; i < 5; i++) {
@Test
public void test1(){
assertThat(assertvalue 1);
}

@Test
public void test2(){
assertThat(assertvalue 2);
}
@Test
public void test3(){
assertThat(assertvalue 3);
}
}

Of course I can use dataProvider or invocationCount and do all asserts in one test case, but if one assert will fail whole test case fail. I want kind of separate one big test case for 3 small test cases Any help appreciated
