如何配置jest来处理SvelteKit的`$lib`别名？

module.exports = {
  moduleNameMapper: {
    '^\\$lib/(.*)$': '<rootDir>/src/lib/$1'
  },
  testPathIgnorePatterns: ['<rootDir>/node_modules/', '<rootDir>/cypress/'],
  transform: {
    '^.+\\.js$': 'babel-jest',
    '^.+\\.svelte$': [
      'svelte-jester',
      {
        preprocess: true
      }
    ]
  },
  setupFilesAfterEnv: ['@testing-library/jest-dom/extend-expect']
};

npm install --save-dev jest babel-jest svelte-jester @testing-library/jest-dom
