testinstances 0.2.1

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')
