automatically setups a mysqld instance in a temporary directory, and destroys it after testing

Project description

testing.mysqld automatically setups a mysqld instance in a temporary directory, and destroys it after testing

Install

Use easy_install (or pip):

$ easy_install testing.mysqld

And testing.mysqld requires MySQL server in your PATH.

Usage

Create MySQL instance using testing.mysqld.Mysqld:

import testing.mysqld
from sqlalchemy import create_engine

# Lanuch new MySQL server
with testing.mysqld.Mysqld() as mysqld:
    # connect to MySQL
    engine = create_engine(mysqld.url())

    # if you use mysqldb or other drivers:
    #   import _mysql
    #   db = _mysql.connect(**mysqld.dsn())

    #
    # do any tests using MySQL...
    #

# MySQL server is terminated here

testing.mysqld.Mysqld executes mysql_install_db and mysqld on instantiation. On deleting Mysqld object, it terminates MySQL instance and removes temporary directory.

If you want a database including tables and any fixtures for your apps, use copy_data_from keyword:

# uses a copy of specified data directory of MySQL.
mysqld = testing.mysqld.Mysqld(copy_data_from='/path/to/your/database')

You can specify parameters for MySQL with my_cnf keyword:

# boot MySQL server without socket listener (use unix-domain socket)
mysqld = testing.mysqld.Mysqld(my_cnf={'skip-networking': None})

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

import unittest
import testing.mysqld

class MyTestCase(unittest.TestCase):
    def setUp(self):
        self.mysqld = testing.mysqld.Mysqld(my_cnf={'skip-networking': None})

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