Jest Snapshot serializer to ensure React Helmet side effects are included in component snapshots.

Install preset using npm:

npm install --save-dev jest-serializer-react-helmet

or yarn:

yarn add --dev jest-serializer-react-helmet

Configure Jest to use the serializer in jest.config.js:

module.exports = {
  snapshotSerializers: ["jest-serializer-react-helmet"]
};

or package.json:

{
  "jest": {
    "snapshotSerializers": ["jest-serializer-react-helmet"]
  }
}
