Support Dynamic Routes with Next v12 (Cannot find module 'next/dist/server/normalize-page-path')

hello, i have this error :

Test suite failed to run

    Cannot find module 'next/dist/server/normalize-page-path' from 'node_modules/next-router-mock/dist/dynamic-routes/extensions-11.1.js'

My version of next.js : “12.1.6”

I published this as a prerelease! Can you test this out, and lmk if it works?

Version 0.6.8-next12.0

As @scottrippey correctly spotted, this file has been moved to the other path in the v12. The provided temporary workaround is almost fine and we have to mark this mock as a virtual like below:

jest.mock(
  'next/dist/server/normalize-page-path',
  () => require('next/dist/shared/lib/page-path/normalize-page-path'),
  { virtual: true } // this is crucial
);

The jest docs about this argument: https://jestjs.io/docs/jest-object#jestmockmodulename-factory-options

The third argument can be used to create virtual mocks – mocks of modules that don’t exist anywhere in the system
