MyRelayComponent.spec.tsx

import rtl from 'react-test-renderer'
import { createMockEnvironment, MockPayloadGenerator } from 'relay-test-utils'

import MyRelayComponent from './MyRelayComponent'

test('Data Render', () => {
  const environment = createMockEnvironment()
  const renderer = rtl.create(<MyRelayComponent environment={environment} />)

  environment.mock.resolveMostRecentOperation(operation => MockPayloadGenerator.generate(operation))

  expect(renderer.root.find(node => node.props['data-testid'] === 'myButton')).toBeDefined()
})
