VistasHow to mock all files in a folder in jest
I have files as follows
widgets
|
--tabs
|
-- __mocks_
|
-- index.ts
-- index.ts
--button
|
-- __mocks_
|
-- index.ts
-- index.ts
Its imported/used in files as
import { Button } from 'common/widgets/button';
I can individually mock each of these.
jest.mock('common/widgets/tabs');
jest.mock('common/widgets/button');
But is there a way to mock them all like add all these to file and import them or do like below with a common mock folder and an index file.
jest.mock('common/widgets');

You can do it this way (P.S. All functions and function calls are just for demonstration:
Folder structure
widgets/button/index.js
// demonstration
const someFunction = () => {
console.log("widgets/button")
}
export default someFunction;
widgets/tabs/index.js
// demonstration
const someFunction = () => {
console.log("widgets/tabs")
}
export default someFunction;
widgets/index.js
export { default as Button } from './button/index';
export { default as Tabs } from './tabs/index';
-- Usage You can import the functions as named import in any file. E.G.: /any/file.js
import { Button, Tabs } from 'common/widgets'
...
So, you should be able to import them into a single mock file.
mock/index.js
jest.mock('common/widgets');

When we import any module in the test file then jest checks whether there is an mock implementation of that module is present in the ./__mocks__ directory or not. If jest founds it then jest will simple mock that module.
Here in your case, you already have mock modules in your ./__mocks__ directories. You don't need jest.mock() api to mock your modules.
Jest mock is meant to mock modules not directories which contains modules.
