In the case of step-i, we are really trying to assert that we step just one
instruction. That's actually not all that hard to test exactly. Just add some
simple arithmetic computation to the test, so it won't have branches, and then
stop at the beginning of the computation, run your step-i plan, and assert that
you did get to the NEXT instruction on the instruction list.
