Do you want to request a feature or report a bug? Bug

What is the current behavior?

Given a file tree:

src/app/modules
├── module1
│   ├── index.js
│   ├── __tests__/
├── module2
│   ├── index.js
│   ├── __tests__/

I use the modules outside of the modules directory by importing them by directory name:

import Module1 from '../modules/module1';
import Module2 from '../modules/module2';

I'd like to be able to mock module1 and module2. However, if I create src/app/modules/module1/__mocks__/index.js and src/app/modules/module2/__mocks__/index.js, I'm given the duplicate manual mock found error from jest-haste-map.

If, however, I try to create src/app/modules/__mocks__/{module1.js,module2.js}, the mocked files are not used.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal repository on GitHub that we can npm install and npm test.

See above behavior.

What is the expected behavior?

I would expect either approach to work, given that the first case uses different paths and the second case uses the pathname of the module.

Run Jest again with --debug and provide the full configuration it prints. Please mention your node and npm version and operating system.

node v6.2.0
npm v3.8.9
OS X 10.11.6

> NODE_ENV=test jest --env jsdom "--debug" "src/app/redux/modules/devices"

jest-haste-map: duplicate manual mock found:
  Module name: index
  Duplicate Mock path: /Users/paul/dev/src/app/modules/push-notification-manager/__mocks__/index.js
This warning is caused by two manual mock files with the same file name.
Jest will use the mock file found in:
/Users/paul/dev/src/app/modules/push-notification-manager/__mocks__/index.js
 Please delete one of the following two files:
 /Users/paul/dev/src/app/modules/image-file/__mocks__/index.js
/Users/paul/dev/src/app/modules/push-notification-manager/__mocks__/index.js
