We actually have two versions of this test. One does 100% totally random actions. The other tries to simulate an actual user (i.e. maintains the state of their cursor, which sheet they are looking at, etc), but still quite random.

So the former finds crazy obscure edges, but the combinatorics make it less likely to hit any particular combination. The latter is the opposite. They pair really well.
