Windows only - Jest testing files are included and try to run in the codebase

[timothyjoh]

Description

I'm not having trouble running the tests per-se, but rather the test files show up in my browser when the code is all compiled together. I'm not specifically including them anywhere. This is giving me errors like "undefined function beforeEach, and function test"

Seems related to #7655 but maybe the opposite?

Steps to reproduce

Using the latest Gatsby: 2.0.63, babel core is at 7.2.0

Expected result

It should ignore the test.js files, as I am not directly including them

Actual result

I get an error page in the browser with ReferenceError: beforeEach is not defined
this also happens with test if i remove the beforeEach statements
The whole site runs normally if I comment out all the tests or delete the files.
This only happens on windows, I'm successful on the mac

@timothyjoh did you manage to solve the issue?

I'm getting the same issue here on windows. However, I do not own a mac machine so can't determine if this is a Windows issue.

I'm currently running windows 10

I've followed the tutorials from the docs. I'm currently only running 1 test on the 404 page just to play around.

this is the link to my github repo here
Cloning and npm install should get you up and running

i'm getting the following compilation error if that helps

i ｢wdm｣: Compiling...

I'll try my best to provide more info if required. I'm currently about to head out for a short vacation so i may not reply so often
