Have you tried spring https://github.com/rails/spring ? Designed to do that kind of hot reloading in development.

I've created a knapsack ruby gem for CI parallelisation that has over 122 million downloads. Primarily due to the fact, Gitlab is using it.

I spin off https://knapsackpro.com from the knapsack gem and we are helping our customers run fast CI builds.

One, the interesting out-of-the-box solution is Knapsack Pro. It helps run your tests in a parallel efficient way.
