Jest Config

Factory functions for creating preset Jest configurations. Primarily used in unison with the Lumos CLI.

Extending config

Update package.json:

{
  "lumos": {
    "jest": {
      "setupFilesAfterEnv": ["@testing-library/jest-dom/extend-expect"]
    }
  }
}

Create file in configs folder:

configs/eslint.js

modules.exports = {
  setupFilesAfterEnv: ['@testing-library/jest-dom/extend-expect'],
};
