jest-resolve fail to resolve json files

[stephenlautier]

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

What is the current behavior?
Currently when there are any dependencies which require .json files, and not explicitly specifying the type .json (not sure if it matters), jest-resolve is throwing an error as following:

 FAIL  src\lint\lint-sass\lint-sass.spec.ts
  ● Test suite failed to run

    Cannot find module './data/all' from 'index.js'

      at Resolver.resolveModule (node_modules\jest-resolve\build\index.js:169:17)
      at Object.<anonymous> (node_modules\known-css-properties\index.js:1:111)

This is the library which throws the error
https://github.com/betit/known-css-properties/blob/master/index.js#L1 (and the import is from a json file), also was getting the same issue from normalize-package-data

I'm currently switching a library from using jasmine (also as a runner) to jest. This has happened in 2 libraries (dependency of a dependency)

What is the expected behavior?
I believe that such an import should work correctly since it works in node and also in jasmine runner.
personally i wouldn't use json files in the first place but that's another story :)

Please provide your exact Jest configuration and mention your Jest, node, yarn/npm version and operating system.

• Jest: 19.0.2
• Node: 7.8.0
• NPM: 4.4.4
• Windows 7

@thymikee precisely, that fixed it!

I had searched quite a bit and didn't find that :(
Not sure if it's documented anywhere but it took me quite some time to figure what was going wrong in the first place.

@thymikee many thanks, especially for the super fast reply :+1:
