The days the OR was put to test, a couple weeks ago, artisan was available for testing, in fact is what I did (along with plant some factories and harvesters). You can be sure you will be able to test all crafting professions. I've got the feeling OR is quite polished about these professions, though I only tested artisan since I couldn't get to higher levels because of the short time OR was tested and the daily wipes. As soon as OR will be 24/7 online we will have the chance to test thoroughly crafters and any other profession.
