if you were writing 1 or 2 slides on designing software so that it's easy (or at least not impossible) to test, what would you list besides what's on this slide?

* Key interfaces are exposed programmatically

* Code is modular: Each part of the code does a small
number of things

* Non-deterministic parts can be determinized

* Eliminate extraneous configuration logic

* Key subsystems can be reinitialized

* Tricky optimizations can be disabled
