I may be unique, but I fear there is no great answer. On the one hand I almost always code it as e.g. assertEqual(actual, expected), which matches my preference for e.g. "if x =3D=3D 5:" rather than "if 5 =3D=3D x:= ". On the other hand in those assert* functions that show a nice diff of two lists, when reading such a diff my expectation is that "old, new" corresponds to "expected, actual". Which then freaks me out until I realize that I coded it as "actual, expected"... And yet "expected, actual" still looks weird to me. :-(

You aren't unique, I feel the same way. But it seems to me that the most important thing is to be consistent, so that I don't freak out for long.
