Log:
#10573: use actual/expected consistently in unittest methods.
Change was requested by M. Foord and R. Hettinger (and G.Brandl for b2).
IMHO, this should be reverted. The API currently doesn't treat these
arguments differently, so they should really be labeled "first" and
"second". Otherwise, the user will wrongly assume that the signature is
asymmetric and that they should be careful about which order they pass
the arguments in.
The error report on assert failure *is* often asymmetrical ;=).
From Michael's post:
"This is particularly relevant for the methods that produce 'diffed'
output on failure - as the order determines whether mismatched items are
missing from the expected or additional to the expected."
This change struck me as a nice bit of polishing.
