I can give you lots of test statistics, for none of which do
I know even the asymptotic distribution.
In n dimensions, let the sample {X_j} have mean vector m
and sample standard covariance matrix C = A*A'. Then
consider the sample averages of exp(i*t'*A^{-1}(X_j-m))
as a function of t. The maximum of the differences of
these averages from exp(-.5*t'*t) for |t| <= 1 is such
a test statistic.
