Abstract
We verify numerically that in the context of general relativity (GR), flat models which have the same and CMB shift parameter but different and also have very similar (within less than 8%) growth of perturbations even though the dark energy density evolution is quite different. This provides a direct connection between geometrical and dynamical tests of dark energy and may be used as a cosmological test of general relativity.
