  • add a snapshot test for the input spec in integration.spec.ts
  • verify that the snapshot is actually the wanted test output before commiting the updated snapshot.

Alternavely, you can:

  • run npm link
  • run npm run build:dev
  • run jest-test-gen <option> in your project of choice

Release

run npm run build run npm publish
