reactjs - Change react-script test to run with .env.development instead of .env.test

Question

I have tried

dotenv_config_path=./.env.development react-scripts test

But it still doesn't use .env.development

how can I force react-scripts test to run with content from .env.development

As suggested in the documentation, NODE_ENV in Jest defaults to test but can be changed with environment variable.

create-react-app provides an opinionated Jest setup. As can be seen here, NODE_ENV is forced to be test. Possible options are to eject, or reinitialize dotenv in Jest global setup or test file, or make process.env.NODE_ENV read-only so it couldn't be redefined by react-scripts, e.g.:

node -r ./test-dev-env.js ./node_modules/react-scripts/scripts/test.js

Where test-dev-env.js is:

Object.defineProperty(process.env, 'NODE_ENV', { value: 'development', writable: false });
