TypeError: require.requireActual is not a function

Question

I'm getting an error on my Jest tests:

 FAIL  test/storyshots.test.ts
  ● Test suite failed to run

    TypeError: require.requireActual is not a function

      1 | import initStoryshots from "@storybook/addon-storyshots"
      2 | 
    > 3 | initStoryshots({
        | ^
      4 |   configPath: "./storybook",
      5 |   framework: "react-native",
      6 | })

      at Object.<anonymous> (test/storyshots.test.ts:3:1)

I'm not using requireActual anywhere in my code. It looks like Storybook does, though.

A Google search turned up only one (since deleted) Stackoverflow question with no answer.

Answer 1

Jest deprecated require.requireActual a while back and recently removed it in version 26.

Downgrade to Jest 25 to fix it, or find what package is using require.requireActual and have them use jest.requireActual instead.

EDIT: Storybook v6.0.0-beta.3 includes an update that adds Jest v26 support.
