# Global Test Environment

You might want to make environment variables that are shared across all of your
tests, you can specify these env vars in the Metlo Config tab on the settings
page:

```yaml YAML theme={null}
globalTestEnv:
  - name: CREDENTIALS
    value: ...
  - name: foo
    value: bar
```

These values can then be accessed in a test like normal environment variables
but with `global` prefix before the name:

```yaml YAML theme={null}
id: 065be84b-818f-4dd0-bb0e-6dc788697060

meta:
  name: /user Test

test:
  - request:
      method: GET
      url: "https://test-user-service.metlo.com/user/{{global.foo}}"
      headers:
        - name: Content-Type
          value: application/json
        - name: x-api-key
          value: "{{global.CREDENTIALS}}"
    assert:
      - resp.status < 300
```
