Comment(by SimonKing):
{{{make ptestlong}}} is not done yet. But at least I can confirm that the
original problem is fixed:
{{{
sage: W = PolynomialRing(InfinitePolynomialRing(QQ,'a'),2,'x,y')
sage: W.is_integral_domain()
True
sage: W = PowerSeriesRing(InfinitePolynomialRing(QQ,'a'),'x')
sage: W
Power Series Ring in x over Infinite polynomial ring in a over Rational
Field
}}}
