@epugh I recall about ~2 months ago, you wrote a test but it didn't work with SSL. Did I share a tip/trick to run tests with SSL that merely involved a setting at the CLI? I forget. If there is no such way to do it, then this PR would be useful.

One thing this PR doesn't do but maybe should is explicitly run with SSL randomization disabled. It only does the inverse right now.

I am trying to remember which one it was, but yeah.. I know we have a lot of SuppressSSL littered about...
