我正在尝试对 react-native 项目进行一些测试，但是 jest 遇到了这个错误，我不知道原因：

 FAIL  __tests__/(tabs)/weather.test.tsx
   Test suite failed to run

    Jest encountered an unexpected token

    Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.

    Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.

    By default "node_modules" folder is ignored by transformers.

    Here's what you can do:
     • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it.
     • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/configuration
    For information about custom transformations, see:
    https://jestjs.io/docs/code-transformation

    Details:

    SyntaxError: Cannot use import statement outside a module

      at Object.require (test-utils.tsx:5:1)
      at Object.require (/Users/j/Downloads/tdd-expo/__tests__/(tabs)../../../../weather.test.tsx:2:1)

这似乎是失败的地方：

    Details:

    /Users/j/Downloads/tdd-expo/node_modules/react-redux/dist/react-redux.legacy-esm.js:34
    import * as React2 from "react";
    ^^^^^^

因此，无法将其导入文件 test-utils.tsx ：

// test-utils.tsx
import { DarkTheme, ThemeProvider } from "@react-navigation/native";
import "@testing-library/jest-native/extend-expect";
import { render } from "@testing-library/react-native";
import React, { PropsWithChildren } from "react";
import { Provider } from "react-redux"; // Is failing to import here

const AllTheProviders = ({ children }: PropsWithChildren) => {
  return (
    <Provider store={{} as any}>
      <ThemeProvider value={DarkTheme}>{children}</ThemeProvider>
    </Provider>
  );
};

const customRender = (ui: React.ReactElement, options: any) =>
  render(ui, { wrapper: AllTheProviders, ...options });

// re-export everything
export * from "@testing-library/react-native";

// override render method
export { customRender as render };

以下是 jest 的配置：

// package.json
{
// ...
  "jest": {
    "preset": "jest-expo",
    "transformIgnorePatterns": [
      "node_modules/(?!((jest-)?react-native|@react-native(-community)?)|expo(nent)?|@expo(nent)?/.*|@expo-google-fonts/.*|react-navigation|@react-navigation/.*|@unimodules/.*|unimodules|sentry-expo|native-base|react-native-svg)"
    ],
    "collectCoverage": true
  },

// ...
}

我遵循了以下指南： https://docs.expo.dev/develop/unit-testing/

并尝试了这个自定义渲染设置： https://testing-library.com/docs/react-testing-library/setup/#custom-render

我期望 jest 能够成功运行，但实际上它导致了“import”错误。

知道发生了什么吗？提前致谢
