Real Clipboard Event using Storybook Interaction Testing?

Question

I did some research on how to test real onPaste Clipboard event with Jest and React-Testing-Library and realized that it is a challenge:

• How to paste clipboard data using React Testing Library?
• How to mock onPast event with React and Jest?
• How to fire and test a real paste event (not simulated by calling the prop) in Jest and Enzyme

Now that Storybook Interactive Testing runs in a real browser, I am hoping it should be possible.

But my test was unsuccessful.

await userEvent.paste(inputEl, 'some text')

Not able to access clipboard data from my handlePaste function:

  const handlePaste = (event: ClipboardEvent<HTMLInputElement>) => {
    event.preventDefault()
    const pasted = event.clipboardData.getData('text/plain')
    ...
  }

TypeError
Cannot read properties of null (reading 'getData')

Thank you!
