Comment (by rws):
Replying to [comment:45 kcrisman]:
> > You can't just test integral(f(x), x), where f is an unevaluated
function (Function('f') in SymPy)? SymPy will always return an unevaluated
integral for that.

> Are you saying we ''should'' test the integrals that can't be solved to
properly test this? I don't think there is a test like this in the
current patch.
Contrary, the code of this ticket is only invoked when SymPy returns an
unevaluated integral. What he suggested was replacing `x` with `f(x)` (for
clarity I guess).
