The secret sauce
Instructions
Profiles a test sample, checks fixes in batches, stops on guardrails. Runs cheap and unattended in CI.
Index
The usual reasons Rails tests are slow and how to spot each one, so the agent gets to the fixes faster.
Docs
The TestProf docs, written with agents in mind. Which profiler to run, and how to read its report.
Playbooks
How to land the big wins, like let_it_be and FactoryDefault, without breaking a single spec.
Examples
Best practices from real Rails apps. Tests that got faster and stayed beautiful.
TestProf
The battle-tested profilers. They show where the time goes and prove the speedup is real.
Sneak peek
Measured, not promised
Mastodon: 7.5k specs, ~10min test run. Make model and request specs at least 2x faster (in three steps). Work in progress.
Score
Known issues fixed, plus best practices.
