Project Description

testinstances is a set of managed instance wrappers to make integration testing with redis and mongodb easier. If you have the binaries on your path, it can handle creating and destroying sandboxed instances for you to test with.

Examples

The API is straightforward and easily embedeed in setup/teardown functions. It also automatically returns a connection to the instance.:

import unittest

from testinstances import RedisInstance

class TestSomeJunk(unittest.TestCase):
  def setUp(self):
    # Set up an instance on port 12345
    self.redis = RedisInstance(12345)

  def tearDown(self):
    self.redis.terminate()

  def test_stuff(self):
    self.redis.conn.set('foo', 'bar')
    self.assertEqual(self.redis.conn.get('foo'), 'bar')

Or, if you wanted to be fancy and avoid the process creation/termination cost for every test case:

import unittest

from testinstances import MongoInstance

class TestSomeJunk(unittest.TestCase):
  @classmethod
  def setUpClass(cls):
    # Set up an instance on port 12345
    cls.mongo = MongoInstance(12345)

  @classmethod
  def tearDownClass(cls):
    cls.mongo.terminate()

  def setUp(self):
    # All instance types implement ``flush``
    self.mongo.flush()

  def test_stuff(self):
    collection = self.mongo.conn['someDB']['someCollection']
    collection.insert({'foo': 'bar'})
    self.assertEqual(collection.find({'foo': 'bar'}).next()['foo'], 'bar')

Developing

To run the tests you need to install all of the databases the tests run:

For Debian/Ubuntu:

$ sudo apt-get install redis-server mongodb-server

For OSX:

$ sudo brew install redis mongodb

Then you just run tox.
