I get the following error every time I try to run test.


  ● Test suite failed to run

    src/repositories/list_contacts/ListContactRepository.test.ts:4:37 - error TS2307: Cannot find module './ListContactRepository' or its corresponding type declarations.

    4 import {ListContactRepository} from './ListContactRepository';
                                          ~~~~~~~~~~~~~~~~~~~~~~~~~

Earlier everything worked fine but this happened after I rename
src/repositories/quick_contacts/QuickListContactRepository.test.ts to

src/repositories/list_contacts/ListContactRepository.test.ts

And run git checkout -b list. After some changes I committed there and come back to previous branch by git checkout dev now I face this error whenever I try to run test.

This file src/repositories/list_contacts/ListContactRepository.test.ts doesn't even exist on my current branch. But jest keep complaining. Any suggestion to solve this will be appreciated.

by default jest doesn't import files correctly so you have to configure jest to do so

in jest config file jest-e2e.json you have to add a moduleNameMapper json object and specify the importing setting to start from root:

"moduleNameMapper": {
    "~src/(.*)": "<rootDir>/src/$1"
  }

after that you need to make sure that jest is applying you modification on jest by clearing the jest cashe

npx jest --clearCache

finally, rerun your test and it should work
