Test ideals are a measure of singularities in positive characteristic, and are analogs of multiplier ideals from characteristic zero. In this talk, I will describe some recent joint work with Karl Schwede on the test ideals of non-principal ideals. In particular, time permitting I will discuss a description of test ideals using regular alterations, as well as positive characteristic global division theorem for test ideals.
