# Disallow importing Jest(no-jest-import) The `jest` object is automatically in scope within every test file. The methods in the `jest` object help create mocks and let you control Jest's overall behavior. It is therefore completely unnecessary to import in `jest`, as Jest doesn't export anything in the first place. ### Rule details This rule reports on any importing of Jest. To name a few: `var jest = require('jest');` `const jest = require('jest');` `import jest from 'jest';` `import {jest as test} from 'jest';` There is no correct usage of this code, other than to not import `jest` in the first place. ## Further Reading \*[The Jest Object](https://facebook.github.io/jest/docs/en/jest-object.html)
