modern-pook

Build Status

This is somewhat of a verbatim copy of h2non/pook, but it doesn't support python 2, or older versions of python 3. Use this one if you need python 3.11 support.

Versatile, expressive and hackable utility library for HTTP traffic mocking and expectations made easy in Python. Heavily inspired by gock.

To get started, see the documentation, how it works, FAQ or examples.

Features

  • Simple, expressive and fluent API.
  • Provides both Pythonic and chainable DSL API styles.
  • Full-featured HTTP response definitions and expectations.
  • Matches any HTTP protocol primitive (URL, method, query params, headers, body...).
  • Full regular expressions capable mock expectations matching.
  • Supports most popular HTTP clients via interceptor adapters.
  • Configurable volatile, persistent or TTL limited mocks.
  • Works with any testing framework/engine (unittest, pytest...).
  • First-class JSON & XML support matching and responses.
  • Supports JSON Schema body matching.
  • Works in both runtime and testing environments.
  • Can be used as decorator and/or via context managers.
  • Supports real networking mode with optional traffic filtering.
  • Map/filter mocks easily for generic or custom mock expectations.
  • Custom user-defined mock matcher functions.
  • Simulated raised error exceptions.
  • Network delay simulation (only available for aiohttp).
  • Pluggable and hackable API.
  • Customizable HTTP traffic mock interceptor engine.
  • Supports third-party mocking engines, such as mocket.
  • Fits good for painless test doubles.
  • Does not support WebSocket traffic mocking.
  • Works with +3.8 (including PyPy).
  • Dependency-less: just 2 small dependencies for JSONSchema and XML tree comparison.

Supported HTTP clients

pook can work with multiple mock engines, however it provides a built-in one by default, which currently supports traffic mocking in the following HTTP clients:

More HTTP clients can be supported progressively.

Note: only recent HTTP client package versions were tested.

Installation

Using pip package manager (requires pip 1.8+):

pip install --upgrade modern-pook

Or install the latest sources from Github:

pip install -e git+git://github.com/odarbelaeze/pook.git#egg=pook

Getting started

See ReadTheDocs documentation:

Documentation Status

API

See annotated API reference documention.

Examples

See examples documentation for full featured code and use case examples.

Basic mocking:

import pook
import requests

@pook.on
def test_my_api():
    mock = pook.get('http://twitter.com/api/1/foobar', reply=404, response_json={'error': 'not found'})

    resp = requests.get('http://twitter.com/api/1/foobar')
    assert resp.status_code == 404
    assert resp.json() == {"error": "not found"}
    assert mock.calls == 1

Using the chainable API DSL:

import pook
import requests

@pook.on
def test_my_api():
    mock = (pook.get('http://twitter.com/api/1/foobar')
              .reply(404)
              .json({'error': 'not found'}))

    resp = requests.get('http://twitter.com/api/1/foobar')
    assert resp.json() == {"error": "not found"}
    assert mock.calls == 1

Using the decorator:

import pook
import requests

@pook.get('http://httpbin.org/status/500', reply=204)
@pook.get('http://httpbin.org/status/400', reply=200)
def fetch(url):
    return requests.get(url)

res = fetch('http://httpbin.org/status/400')
print('#1 status:', res.status_code)

res = fetch('http://httpbin.org/status/500')
print('#2 status:', res.status_code)

Simple unittest integration:

import pook
import unittest
import requests


class TestUnitTestEngine(unittest.TestCase):

    @pook.on
    def test_request(self):
        pook.get('server.com/foo').reply(204)
        res = requests.get('http://server.com/foo')
        self.assertEqual(res.status_code, 204)

    def test_request_with_context_manager(self):
        with pook.use():
            pook.get('server.com/bar', reply=204)
            res = requests.get('http://server.com/bar')
            self.assertEqual(res.status_code, 204)

Using the context manager for isolated HTTP traffic interception blocks:

import pook
import requests

# Enable HTTP traffic interceptor
with pook.use():
    pook.get('http://httpbin.org/status/500', reply=204)

    res = requests.get('http://httpbin.org/status/500')
    print('#1 status:', res.status_code)

# Interception-free HTTP traffic
res = requests.get('http://httpbin.org/status/200')
print('#2 status:', res.status_code)

Example using mocket Python library as underlying mock engine:

import pook
import requests
from mocket.plugins.pook_mock_engine import MocketEngine

# Use mocket library as underlying mock engine
pook.set_mock_engine(MocketEngine)

# Explicitly enable pook HTTP mocking (optional)
pook.on()

# Target server URL to mock out
url = 'http://twitter.com/api/1/foobar'

# Define your mock
mock = pook.get(url,
                reply=404, times=2,
                headers={'content-type': 'application/json'},
                response_json={'error': 'foo'})

# Run first HTTP request
requests.get(url)
assert mock.calls == 1

# Run second HTTP request
res = requests.get(url)
assert mock.calls == 2

# Assert response data
assert res.status_code == 404
assert res.json() == {'error': 'foo'}

# Explicitly disable pook (optional)
pook.off()
