@Hypnosphi any ideas here?

there is a reference to window in

storybook/lib/addons/src/hooks.ts

Line 147 in b41b3ab

const prevContext = window.STORYBOOK_HOOKS_CONTEXT;

but window does not exist in react native

[loic-lopez]

As a temporary workaround you can do:

import initStoryshots from "@storybook/addon-storyshots"
import { merge } from "lodash-es"

jest.mock("global", () => merge(global, { window: { STORYBOOK_HOOKS_CONTEXT: "" } }));

describe("storybook tests", () => {
  initStoryshots({
    configPath: "./storybook",
    framework: "react-native"
  })
})

@loic-lopez when I tried your code(to solve this problem) I got this error message in console:

babel-plugin-jest-hoist: The module factory of `jest.mock()` is not allowed to reference any out-of-scope variables.

Note: This is a precaution to guard against uninitialized mock variables. If it is ensured that the mock is required lazily, variable names prefixed with `mock` (case insensitive) are permitted.

Could you please help me, what I did wrong?

@vladstart1 I have imported merge function from lodash

Your error:

Invalid variable access: merge

You can do:

jest.mock("global", () => Object.assign(global, { window: { STORYBOOK_HOOKS_CONTEXT: "" } }));
