    @class ETA_InterpolateGradient2DTest
    @brief Simple ETA to check the evaluation of a gradient interpolation and the use of SmallMatrix costants in expressions

    @author L. Pasquale <luca.pasquale@mail.polimi.it>

    This test integrates the trace of the gradient of \f$u=\left(\begin{array}{c} x \\ 2y \end{array}\right)\f$ on the domain (-1,1)x(-1,1) and compares it to its expected value (12)
