We proposed a new method testing different gravitational potential models for galaxies with the Jeans equations. It is a universal one compared with the traditional two-integral velocity dispersion test. By using both rotation curve, velocity dispersion, and escape velocity data, we tested QUMOND vs. CDM in the Milky Way and the M31.
