Back in 2014 I work on a project where we had ~15min test suite running on CI and this was painful so I started working on open source solution knapsack for CI parallelisation for Ruby tests. Later on developed more advanced way with dynamic tests allocation across parallel CI nodes not only for Ruby to get CI build as fast as possible. To give you some idea how it works check https://docs.knapsackpro.com/2017/auto-balancing-7-hours-tests-between-100-parallel-jobs-on-ci-buildkite-example https://docs.knapsackpro.com/2017/auto-balancing-7-hours-tes... or watch video https://www.youtube.com/watch?v=hUEB1XDKEFY https://www.youtube.com/watch?v=hUEB1XDKEFY
