        Download
          https://pypi.python.org/pypi/testing.postgresql
        
        Install
        =======
        Use pip::
        
           $ pip install testing.postgresql
        
        And ``testing.postgresql`` requires PostgreSQL server in your PATH.
        
        
        Usage
        =====
        Create PostgreSQL instance using ``testing.postgresql.Postgresql``::
        
          import testing.postgresql
          from sqlalchemy import create_engine
        
          # Lanuch new PostgreSQL server
          with testing.postgresql.Postgresql() as postgresql:
              # connect to PostgreSQL
              engine = create_engine(postgresql.url())
        
              # if you use postgresql or other drivers:
              #   import psycopg2
              #   db = psycopg2.connect(**postgresql.dsn())
        
              #
              # do any tests using PostgreSQL...
              #
        
          # PostgreSQL server is terminated here
        
        
        ``testing.postgresql.Postgresql`` executes ``initdb`` and ``postgres`` on instantiation.
        On deleting Postgresql object, it terminates PostgreSQL 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 PostgreSQL.
          postgresql = testing.postgresql.Postgresql(copy_data_from='/path/to/your/database')
        
        
        For example, you can setup new PostgreSQL server for each testcases on setUp() method::
        
          import unittest
          import testing.postgresql
        
          class MyTestCase(unittest.TestCase):
              def setUp(self):
                  self.postgresql = testing.postgresql.Postgresql()
        
              def tearDown(self):
                  self.postgresql.stop()
        
        
        To make your tests faster
        -------------------------
        
        ``testing.postgresql.Postgresql`` invokes ``initdb`` command on every instantiation.
        That is very simple. But, in many cases, it is very waste that generating brandnew database for each testcase.
        
        To optimize the behavior, use ``testing.postgresql.PostgresqlFactory``.
        The factory class is able to cache the generated database beyond the testcases,
        and it reduces the number of invocation of ``initdb`` command::
        
          import unittest
          import testing.postgresql
        
          # Generate Postgresql class which shares the generated database
          Postgresql = testing.postgresql.PostgresqlFactory(cache_initialized_db=True)
        
        
          def tearDownModule(self):
              # clear cached database at end of tests
              Postgresql.clear_cache()
        
        
          class MyTestCase(unittest.TestCase):
              def setUp(self):
                  # Use the generated Postgresql class instead of testing.postgresql.Postgresql
                  self.postgresql = Postgresql()
        
              def tearDown(self):
                  self.postgresql.stop()
        
        If you want to insert fixtures to the cached database, use ``initdb_handler`` option::
        
          # create initial data on create as fixtures into the database
          def handler(postgresql):
              conn = psycopg2.connect(**postgresql.dsn())
              cursor = conn.cursor()
              cursor.execute("CREATE TABLE hello(id int, value varchar(256))")
              cursor.execute("INSERT INTO hello values(1, 'hello'), (2, 'ciao')")
              cursor.close()
              conn.commit()
              conn.close()
        
          # Use `handler()` on initialize database
          Postgresql = testing.postgresql.PostgresqlFactory(cache_initialized_db=True,
                                                            on_initialized=handler)
