the class KafkaSerdeFactoryTest method shouldHandle.

private static void shouldHandle(final SqlType fieldSchema, final Object value) {
    // Given:
    final PersistenceSchema schema = schemaWithFieldOfType(fieldSchema);
    final Serde<List<?>> serde = KafkaSerdeFactory.createSerde(schema);
    final List<Object> values = Collections.singletonList(value);
    // When:
    final byte[] bytes = serde.serializer().serialize("topic", values);
    final Object result = serde.deserializer().deserialize("topic", bytes);
    // Then:
    assertThat(result, is(values));
}
