electron mocha temp dir locked; unlink error

[grantfree035]

Environment:

• electron-mocha: 3.0.4
• electron-prebuilt: 1.3.3
• OS: Windows 7 x64

I am receiving and unlink error as the test is exiting.
$ electron-mocha ./build/mocha.js --renderer

Here is the output at the end of the test:

{ Error: EBUSY: resource busy or locked, unlink 'C:\Users\ADMINI~1\AppData\Local\Temp\electron-mocha-FINsw6\Cookies'

I previously was using electron-mocha 2.1.0 without errors so I'm not sure which version is the culprit (unless the culprit is me being a gumby)

I've seen this unlink issue was before and remembered that it was resolved in 1.2.0 but it seemed to have popped up again.
I know for main processes you have to explicitly exit but I'm under the assumption the renderer processes will exit on their own.

Are you testing any code that might be opening windows (even when they're not visible)?

We had to change force closing windows for multiple reasons (e.g., see #60 for context); open windows are the main reason I've seen for Windows failing when removing the temp dir.

@inukshuk I found the culprit. I am using a module called app-root-path,, which lets me require from the root directory.

After skimming through their commits I found they have to adjust their search method by using an electron remote object. Commit Reference

After reading through electron API, I'm thinking that the modules code this is causing binding issues with the main process.
