TypeScript testing

The cross-cutting testing.md applies — test-driven development is required, and you never widen a package's exports just to reach something from a test. This page covers the TypeScript-specific conventions.

  • Use the repo's internal test configuration; a package generated with pnpm create-pyth-package comes wired for it.
  • Locate tests next to the code they exercise, with a *.test.ts filename (*.test.tsx for a React component). Import from the module's own source rather than from the package's public entry point, so a test can reach an internal without it being added to src/index.ts.
  • Test the behaviour a real caller would observe, not the implementation details.
