PlanetScale Rails test suite runs in 1 minute on Buildkite
3 min read
PlanetScale's Rails test suite runs in 1 minute on Buildkite using 64-core machines. The team parallelizes tests with minitest, running 64 workers only on CI. Local serial execution takes 12 minutes. FactoryBot test data setup was the main bottleneck after parallelization.
