Make Integration Tests Easier
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-serverFor OSX:
$ sudo brew install redis mongodbThen you just run tox.

- New Instance Kinds
- Kafka
- Zookeeper
- Documentation and ReadTheDocs
- Travis-CI
