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

Use the Arguments.of() factory from org.junit.jupiter.params.provider.Arguments to wrap your arguments:

static Stream stringArrayProvider() {
    return Stream.of(
            Arguments.of((Object) new String[]{"1", "2"}),
            Arguments.of((Object) new String[]{"1", "2", "3"})
    );
}
