In fact we already have parallelization, but it doesn’t work on Travis because we only have one core in our machines.
To run railties tests in parallel you only need to specify the CORES environment variable. CORES=4 rake test I don’t think it is worth to split this build, it doesn’t fail often, and even if it does we don’t take in consideration before merging. We prefer to fix the build after merging than wait the build to run and ask contributors to fix the build.
