Environment key "jest/globals" is unknown

[nickserv]

I couldn't use { "jest/globals": true } as recommended in the readme, so I'm using the built in Jest env with { "jest": true }.

Config

{
  "env": { 
    "jest/globals": true
  },
  "extends": [
    "plugin:jest/recommended"
  ]
}

I believe ESLint processes the configuration file as it reads it, so try declaring the env block after the extends block.

I'm still seeing this error after swapping the order.

I completely misread your code, sorry. If you're extending from the recommended jest plugin (instead of just using the plugin), you shouldn't need to explicitly declare jest/globals, since it is already declared by the recommended configuration:

I didn't notice that, thanks! Removing the Jest env fixed it.

Note that I have the same error and I cannot use the "extends" solution, see #128

The extends in overrides is working great lately. F.e., I have the following in my eslintrc just for test files:

  overrides: [
    {
      files: ['**/*.test.js'],
      extends: ['plugin:jest/recommended', 'plugin:jest/style'],
    },
  ],

I have also faced this issue and solved by following steps:

Update Package.json(Remove "react-app/jest" from extends array

"eslintConfig": { "extends": [ "react-app" ] },
Run npm install and check again It works It works fine for me
