__mocks__
(no-mocks-import
)When using jest.mock
, your tests (just like the code being tested) should
import from ./x
, not ./__mocks__/x
. Not following this rule can lead to
confusion, because you will have multiple instances of the mocked module:
jest.mock('./x');
const x1 = require('./x');
const x2 = require('./__mocks__/x');
test('x', () => {
expect(x1).toBe(x2); // fails! They are both instances of `./__mocks__/x`, but not referentially equal
});
This rule reports imports from a path containing a __mocks__
component.
Example violations:
import thing from './__mocks__/index';
require('./__mocks__/index');
require('__mocks__');
