Each case is a small workspace and the outcome a user would see. All six

tools run the same 984 cases, each in a sandbox.

vx 747b26f · Turborepo 2.11.10 · Nx 24.0.2 · Vite Task 1.4.0 · moon 2.6.5 · Nix 2.34.6 · 2026-11-07 · every case

The cases come from every tool's own tests

The cases are compiled from the test suites of Nx, Turborepo, Vite

Task, moon, Nix and vx. A case names no tool's config. It says which

projects exist, what each task runs, and what must hold afterwards.

A thin adapter turns the case into each tool's own config. The harness

marks each command as it starts and ends, so "ran" means it ran.
