Weak gravitational lensing is a promising probe of modified gravity. In this talk I will first describe our approach to test gravity with the Dark Energy Survey weak lensing and clustering measurements. I will then present a new approach I proposed to classify modified gravity theories using Self-Organizing Maps in order to efficiently test gravity with future surveys like Euclid or LSST. I will end the talk by summarizing my future research projects aiming at testing gravity using weak lensing measurements from the large surveys of the 2020s.
