What problem does it solve? Slow test suites waste developer time and delay feedback loops, but teams often lack a systematic way to measure baseline performance, audit runner configuration, and identify which fixes deliver the most speedup. ## Core Features & Use Cases - Baseline Measurement: Runs the test suite multiple times, computes median timing and stability, and saves a baseline JSON for later comparison. - TP1-TP17 Config Audit: Scores Vitest, Jest, or pytest configuration against a 17-item checklist covering transforms, workers, caching, coverage tools, and isolation. - Slow Test Classification: Identifies the slowest test files and classifies causes such as heavy setup, real timers, DOM-heavy rendering, and sequential async calls. - Use Case: A team with a 10-minute Jest suite runs a full audit, discovers the transform is not using @swc/jest and workers are misconfigured, applies the ranked config diffs, then verifies a 40% speedup against the saved baseline. ## Quick Start Run a full test suite performance audit on this project and produce an impact-ranked action plan.
