[Question] about process.env

[ericcheunghk01]

Dear vladgolubev,

I'm new into Jest

I would like to ask any reason behind to use a persistent json file to get mongo db_name mongo_url, etc.

As I saw this line of code. Why don't we just return process.env.something instead of save into a new json file?

I'm using process.env in my project:

Is there a way to customize the name of the variable? in my case I use MONGODB_URL because that's the name Now.sh set on deploy, and Heroku use MONGODB_URI

@leosuncin you can make little pr to set variable name from the configuration ;)
