If we are busy nitpicking, why are we saying "found Y"? Nothing was *found* by the callee, it just *got* an argument. So it should be "expected X, but got Y". Personally, I think the "but" is superfluous: the contradiction is already implied, so "expected X, got Y" is terser and conveys the meaning just as well.
