I have one actual crochet pattern up for download on Ravelry (it's free because it's for dolls of the South Park characters, hurray copyright!). I didn't have a pattern tester, but I did make three dolls with an identical pattern so it was sort of tested? I just read it over myself for typos and then put it up with a warning that it wasn't tested and to message me if there were problems.

A lot like what I typically do with fanfic, actually....
