testing.cassandra3 1.3.0

Install

Use easy_install (or pip):

$ easy_install testing.cassandra3

And testing.cassandra3 requires Cassandra server.

Usage

Create Cassandra instance using testing.cassandra3.Cassandra:

import cassandra
import testing.cassandra3

# Launch new Cassandra server
with testing.cassandra3.Cassandra as cassandra:
    conn = cassandra.cluster.Cluster(**cassandra.connection_params())
    #
    # do any tests using Cassandra...
    #

# Cassandra server is terminated here

testing.cassandra3 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.cassandra3.Cassandra(copy_data_from='/path/to/your/database')

testing.cassandra3.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.cassandra3.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.cassandra3.Cassandra(cassandra_yaml={'rpc_port': 12345})

For example, you can setup new Cassandra server for each testcases on setUp() method:

import unittest
import testing.cassandra3

class MyTestCase(unittest.TestCase):
    def setUp(self):
        self.cassandra = testing.cassandra3.Cassandra()

    def tearDown(self):
        self.cassandra.stop()
