MongoTest 0.1.0

A Python library to ease testing applications that rely on MongoDB as a datastore

# MongoDB Test Util

This library provides a handful of useful functionality for easing the testing of systems that rely on MongoDB as a datastore

## Start and Teardown mongod

For most use cases, you can use this snippet to startup a mongod instance for your test environment

from mongo_test.handlers import startup_handle startup_handle()

To tear an instance down if one exists:

from mongo_test.handlers import teardown_handle teardown_handle()

## Fixtures

MongoTest allows you to specify fixtures in yaml, with a few conveniences

i.e.

from mongo_test.fixtures import setup_data import_data([path, ...])

A sample yaml file would look something like:

user_fixture.yml
configuration:
collection: users drop: true
simple_user:
_id: !oid 1 username: idbentley first_name: Ian last_name: Bentley

!oid is a custom constructor provided by MongoTest to allow you to test object ids as having any integer seed you specify. You can access the constructor directly with:

from mongo_test.fixtures import oid_con id = oid_con(1)

## A complete example

Assuming that you've used the startup_handler to setup a mongod and that we have the above user_fixture.yml on path.

test_user.py

import pymongo from mongo_test.fixtures import setup_data, oid_con

conn = MongoClient(port=27018) db = conn.myapp

def setup():
# Load fixture before each test. setup_data(['path/to/user_fixture.yml'], db)
def test_find_user():
# Fetch user by id user = db.users.find_one(query={'_id': oid_con(1)}) # Check pymongo works as advertised. assert account['_id'] == oid_con(1) assert account['username'] == "idbentley"
