you can specify the mehtod by:
Method->Oscillatory
other
Possible settings for Method are GaussKronrod, DoubleExponential, Trapezoidal,
Oscillatory, MultiDimensional, MonteCarlo, and QuasiMonteCarlo. GaussKronrod
and MultiDimensional are adaptive methods. MonteCarlo and QuasiMonteCarlo are
randomized methods, appropriate for high-dimensional integrals.
(it is in the help for nintegrate)
