graphql-easy-mocks --port 9000 -f schema.graphql -m mocks.js

// mocks.js

const faker = require('faker')

module.exports = {
    String: () => 'works!',
    Int: () => faker.random.number(100),
}

Then start the server with the app

"scripts": {
    "start": "REACT_APP_TESTING=1 concurrently 'npm:mock-server' 'react-scripts start'",
    "mock-server": "graphql-easy-mocks -p 9000 -f schema.graphql -m mocks.js",
}

Then use it as your server url inside your app.

import ApolloClient from 'apollo-boost'

const uri = process.env.REACT_APP_TESTING
    ? 'http://localhost:9000'
    : 'https://countries.trevorblades.com'
export default new ApolloClient({
    uri,
})
