ReferenceError: expect is not defined

When I add import '@testing-library/jest-native/extend-expect'; inside my setup.js which is referenced in setupFiles inside my jest-config.json, I get this error on every test:

ReferenceError: expect is not defined

When I reference it in setupFilesAfterEnv instead, it’s all working fine.

I’d be happy to push a PR to add that gotcha in the README if the maintainers thing it makes sense.

• react-native: 0.63.2
• @testing-library/react-native: 7.0.2
• jest: 26.5.2
• node version: 10.16.3

Relevant code or config:

{
  "preset": "react-native",
  "globals": {
    "__TEST__": true,
    "window": {}
  },
  "rootDir": "../",
  "setupFiles": [
    "./jest/setup.js",
    "./node_modules/react-native-gesture-handler/jestSetup.js"
  ],
  "setupFilesAfterEnv": [
    "./jest/setupAfterEnv.js"
  ],
...
}
