automatically setups a cassandra instance in a temporary directory, and destroys it after testing
Project description
testing.cassandra automatically setups a cassandra instance in a temporary directory, and destroys it after testing
Install
Use easy_install (or pip):
$ easy_install testing.cassandra
And testing.cassandra requires Cassandra server.
Usage
Create Cassandra instance using testing.cassandra.Cassandra:
import pycassa import testing.cassandra # Launch new Cassandra server with testing.cassandra.Cassandra as cassandra: conn = pycassa.pool.ConnectionPool('test', cassandra.server_list()) # # do any tests using Cassandra... # # Cassandra server is terminated here
testing.cassandra automatically searchs for cassandra files in /usr/local/. If you install cassandra to other directory, set cassandra_home keyword:
# uses a copy of specified data directory of Cassandra. cassandra = testing.cassandra.Cassandra(copy_data_from='/path/to/your/database')
testing.cassandra.Cassandra executes cassandra on instantiation. On deleting Cassandra object, it terminates Cassandra instance and removes temporary directory.
If you want a database including column families and any fixtures for your apps, use copy_data_from keyword:
# uses a copy of specified data directory of Cassandra. cassandra = testing.cassandra.Cassandra(copy_data_from='/path/to/your/database')
You can specify parameters for Cassandra with cassandra_yaml keyword:
# boot Cassandra server listens on 12345 port cassandra = testing.cassandra.Cassandra(cassandra_yaml={'rpc_port': 12345})
For example, you can setup new Cassandra server for each testcases on setUp() method:
import unittest import testing.cassandra class MyTestCase(unittest.TestCase): def setUp(self): self.cassandra = testing.cassandra.Cassandra() def tearDown(self): self.cassandra.stop()
