title: Environment Variables

|
|
Jest sets the following environment variables:
|
|
|
|
### `NODE_ENV`
|
|
|
|
Set to `'test'` if it's not already set to something else.
|
|
|
|
### `JEST_WORKER_ID`
|
|
|
|
Each worker process is assigned a unique id (index-based that starts with `1`). This is set to `1` for all tests when [`runInBand`](CLI.md#--runinband) is set to true.
