JUnit4 now allows specifying a name attribute to the Parameterized annotation, such that you can specify a naming pattern from the index and toString methods of the arguments. E.g.:

@Parameters(name = "{index}: fib({0})={1}")
public static Iterable data() {
    return Arrays.asList(new Object[][] { { 0, 0 }, { 1, 1 }, { 2, 1 },
            { 3, 2 }, { 4, 3 }, { 5, 5 }, { 6, 8 } });
}
