How can I write a test to test what happens when iframeresizer onMessage is invoked? #1173

Is there a way to simulate onMessage being invoked in react-testing-library? I've tried:

      const iframe = screen.getByTitle('iframe') as HTMLIFrameElement
      const TEST_MESSAGE = 'test-message'
      iframe.contentWindow?.postMessage(TEST_MESSAGE, window.location.origin)

but that doesn't seem to work.

Good question, I think that is more for Stack Overflow
