  We study two different methods to test Gaussianity in CMB maps. One of them
is based on the partition function and the other on the morphology of hot and
cold spots. The partition function contains information on all the moments and
scales, being a useful quantity to compress the large data sets expected from
future space missions like Planck. In particular, it contains much richer
information than the one available through the radiation power spectrum. The
second method utilizes morphological properties of hot and cold spots such as
the eccentricity and number of spots in CMB maps. We study the performance of
both methods in detecting non-Gaussian features in small scale CMB simulated
maps as those which will be provided by the Planck mission.
