Test::Database::Handle(3pm) User Contributed Perl Documentation Test::Database::Handle(3pm)
NAME
Test::Database::Handle - A class for Test::Database handles
SYNOPSIS
use Test::Database;
my $handle = Test::Database->handle(@requests);
my $dbh = $handle->dbh();
DESCRIPTION
"Test::Database::Handle" is a very simple class for encapsulating the information about a test database handle.
"Test::Database::Handle" objects are used within a test script to obtain the necessary information about a test database handle. Handles
are obtained through the "Test::Database->handles()" or "Test::Database->handle()" methods.
METHODS
"Test::Database::Handle" provides the following methods:
new( %args )
Return a new "Test::Database::Handle" with the given parameters ("dsn", "username", "password").
The only mandatory argument is "dsn".
The following accessors are available.
dsn()
Return the Data Source Name.
username()
Return the connection username.
password()
Return the connection password.
connection_info()
Return the connection information triplet ("dsn", "username", "password").
dbh( [ $attr ] )
Return the DBI database handle obtained when connecting with the connection triplet returned by "connection_info()".
The optional parameter $attr is a reference to a hash of connection attributes, passed directly to DBI's "connect()" method.
name()
Return the database name attached to the handle.
dbd()
Return the DBI driver name, as computed from the "dsn".
driver()
Return the "Test::Database::Driver" object attached to the handle.
