"""Mock service for testing Service integration
|
|
|
|
A JupyterHub service running a basic HTTP server.
|
|
Used by the mockservice fixtures.
|
|
|
|
Handlers allow:
|
|
|
|
- echoing proxied URLs back
|
|
- retrieving service's environment variables
|
|
- testing service's API access to the Hub retrieval of sys.argv.
