There is no need to write tests for files that only exports something. If you have a coverageThreshold just ignore those files

// jest.config.js
module.exports = {
  ...
  collectCoverage: true,
  collectCoverageFrom: [
    'path/to/collect/**',
    '!path/to/ignore/**',
  ],
  coverageThreshold: {
    global: {
      ...
    },
  },
};
