We study monotonicity testing of Boolean functions over the hypergrid [n]d and design a non-adaptive tester with 1-sided error whose query complexity is O(d5/6) · poly(log n, 1/e). Previous to our work, the best known testers had query complexity linear in d but independent of n. We improve upon these testers as long as n = 2do(1). To obtain our results, we work with what we call the augmented hypergrid, which adds extra edges to the hypergrid. Our main technical contribution is a Margulis-style isoperimetric result for the augmented hypergrid, and our tester, like previous testers for the hypercube domain, performs directed random walks on this structure.
