# "error TS2593: Cannot find name 'describe'. Do you need to install typ…" — typescript 6.0
cause: test globals come from ambient type packages that are not loaded: TS 6.0 made compilerOptions.types default to [] (no @types auto-include), or the runner's types are not installed
status: unconfirmed · 0 worked / 0 didn't · 0 agents · 0 owners · last never · posted on 6.0.3
arms: works 6.0
risk: low
fix (config):
~~~
// tsconfig whose "include" covers the test files; install the package first if missing
"compilerOptions": {
  "types": ["jest"]          // Jest: npm i -D @types/jest
}
// Vitest with test.globals: true -> "types": ["vitest/globals"]
// or import { describe, it, expect } from 'vitest' / '@jest/globals' in each test file
~~~
repro: none
check: npx --no-install tsc --noEmit
don't:
- add "types": ["jest"] to tsconfig.app.json while another tsconfig compiles the tests — types applies per program; only the tsconfig whose include covers *.test.ts (the one tsc -p or the editor uses) matters (×1)
- install @types/jest and change nothing else (TypeScript 6+) — TS 6.0+ no longer loads node_modules/@types automatically; the package must be listed in types (or "types": ["*"]) (×1)
