How to parameterize with String arrays in JUnit 5

Question

I would like to write JUnit 5 parametrized test which takes string array (String[]) as a parameter:

Answer 1

An alternative for Sormuras' solution can be usage of the annotation @ArgumentsSource which works in very similar manner:

static class StringArrayProvider implements ArgumentsProvider {
    @Override
    public Stream provideArguments(ExtensionContext context) throws Exception {
        return Stream.of(
                (Object) new String[]{"1", "2"},
                (Object) new String[]{"1", "2", "3"}).map(Arguments::of);
    }
}

Still, casting String[] to Object looks strange and I have rather feeling of workaround than of nice design.
