Loose server is a simple configurable server. It can be used to create temporary servers, dynamically add or remove endpoints and set responses for them from an application.

Usage

Loose server has 2 variations:

• Standalone server with API to manage rules via HTTP.
• Flask application that can be used as a configurable mock in unit-tests.

Standalone server

A server can be started by the command::

$ python -m looseserver.server.run

• Serving Flask app "run" (lazy loading)
• Environment: production WARNING: Do not use the development server in a production environment. Use a production WSGI server instead.
• Debug mode: off
• Running on http://127.0.0.1:50000/ (Press CTRL+C to quit)

All configurable endpoint have a common prefix. By default it is /routes/::

from looseserver.client.http import HTTPClient from looseserver.default.client.rule import PathRule from looseserver.default.client.response import FixedResponse client = HTTPClient(base_url="http://127.0.0.1:50000/_configuration/") path_rule_spec = PathRule(path="example") path_rule = client.create_rule(rule=path_rule_spec) json_response = FixedResponse(status=200, headers={"Content-Type": "application/json"}, body='{"key": "value"}') client.set_response(rule_id=path_rule.rule_id, response=json_response)

The response can be obtained by the following response::

$ curl http://127.0.0.1:50000/routes/example -i HTTP/1.0 200 OK Content-Type: application/json Content-Length: 16 Server: Werkzeug/0.15.2 Python/3.5.2 Date: Fri, 05 Apr 2019 14:08:50 GMT

{"key": "value"}

Configurable mock

Loose server can be used as a mock server in the following way

from looseserver.server.run import configure_application from looseserver.client.flask import FlaskClient from looseserver.default.client.rule import PathRule from looseserver.default.client.response import FixedResponse application = configure_application(base_endpoint="/routes/", configuration_endpoint="/_configuration/") client = FlaskClient(base_url="/_configuration/", application_client=application.test_client()) path_rule_spec = PathRule(path="example") path_rule = client.create_rule(rule=path_rule_spec) json_response = FixedResponse(status=200, headers={"Content-Type": "application/json"}, body='{"key": "value"}') client.set_response(rule_id=path_rule.rule_id, response=json_response) response = application.test_client().get("/routes/example") response.headers Headers([('Content-Type', 'application/json'), ('Content-Length', '16')]) response.json {'key': 'value'}
