Recent advances in cosmology provide both the motivation and the data to probe gravity on the largest scales available
to observation. I will revise the landscape of gravitational theories, focusing on modern scalar-tensor theories and their
cosmological implications. Then I will present the ongoing effort to test gravity in novel regimes such as the early
universe and ultra-large scales, as well as using mildly non-linear effects. I will also introduce the hi_class code
(www.hiclass-code.net), which is central to this program.
