hm, seems like an old conversation, but maybe even more relevant now -- with the current "microservice" craze, I found myself writing silly little one-off servers a lot just to provide integration testing in dev environments. I finally got sick of it and made

which allows you to mock out servers quickly without having to write actual code.
