Speed up Rails/Rspec test by parallelization + asset pre-precompile + Gitlab-CI/Coverage integration

Read Original

It explains steps to enable example status persistence, generate workload-balanced test groups, and configure CI runners to cut deployment times significantly (e.g., from 50 to under 20 minutes).
