The large scale structure formation in the standard Einstein gravity at later time is uniquely determined by the expansion history H(z) measured by the geometrical factor. A possible departure from the expected standard structure formation is detectable by growth structure test. We design new deviation parameters to test standard gravity at large scales and estimate the expected errors by weak lensing experiment. The effective Newtonian constant GN at the present time can be constrained around 10% accuracy by measuring the difference curvature perturbations (Φ-Ψ)/2 within 2% accuracy.
