@Test
    public void shouldGetEngineByName() throws Exception {
        final GremlinScriptEngine scriptEngine = manager.getEngineByName(ENGINE_TO_TEST);
        assertEquals(ENGINE_TO_TEST, scriptEngine.getFactory().getEngineName());
    }
This is an important test case in that it validates that core features of {@code ScriptEngine} instances that claim
to be "Gremlin-enabled" work in the expected fashion.
