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.load (node_modules/@storybook/addon-storyshots/dist/frameworks/react-native/loader.js:23:29)       at Object.loadFramework [as default] (node_modules/@storybook/addon-storyshots/dist/frameworks/frameworkLoader.js:26:19)       at testStorySnapshots (node_modules/@storybook/addon-storyshots/dist/api/index.js:48:14)       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.
