NAME

       Test::MockDBI - Mocked DBI interface for testing purposes

SYNOPSIS

         use Test::MockDBI;

         my $mi = Test::MockDBI::get_instance();

         Sets a fake return value for the rows statementhandler
         $mi->set_retval( method => rows, retval => sub{ return scalar( @somearray ); });

         $mi->set_retval( method => 'bind_param', retval => undef);
         Same as:
         $mi->bad_method('bind_param');

         You can also specify return values for specific sqls
         $mi->set_retval( method => rows, retval => sub{ return scalar( @somearray ); }, sql => 'select id from names');

         $mi->set_retval( method => 'bind_param', retval => undef, sql => 'select id from names where id < ?');
         Same as:
         $mi->bad_method('bind_param', 'select id from names where id < ?');

PUBLIC INTERFACE

         Methods available on the Test::MockDBI instance.

       reset()
             Method for reseting all mock returnvalues \ bad_params etc

       bad_method()
             This method is basically a alias for calling set_retval with the return value undef.

             Args:
               $method_name              - The name of the method which should return undef
               $matching_sql (Optional)  - The sql matching condition

             Returns:
               On success: 1
               On failure: undef

             The method also supports calling the method with the following arguments:
             $method_name, $dbi_testing_type, $matching_sql
             This will issue a warning as it is deprecated.

       bad_param()
             Args:
               $p_value        - The value that will cause bind_param to return undef
               $sql (Optional) - The sql matching condition

             Returns:
               On success: 1
               On failure: undef

             The method also supports calling the method with the following arguments:
             $dbi_testing_type, $p_num, $p_value
             This will issue a warning as it is deprecated.

       set_retval()
             Method for setting a return value for the specific method.

             Args:(Keys in a hash)
               method             - The method that should return the provided value
               retval             - The data which should be returned
               sql    (Optional)  - Matching sql. The return value will only be
                                     returned for the provided method if the sql matches
                                     a regex compiled by using this string

             Returnvalues:
               On success: 1
               On failure: undef

             Example usage:

               #fetchrow_hashref will shift one hashref from the list each time its called if the sql matches the sql provided, this will happend
               #until the return list is empty.
               $inst->set_retval( method => 'fetchrow_hashref',
                                 retval => [ { letter => 'a' }, { letter => 'b' }, { letter => 'c' }  ],
                                 sql => 'select * from letters' )

               #execute will default return undef
               $inst->set_retval( method => 'execute', retval => undef)

               #Execute will return 10 for sql 'select * from cars'
               $inst->set_retval( method => 'execute', retval => undef);
               $inst->set_retval( method => 'execute', retval => 10, sql => 'select * from cars');

       set_inout_value()
             Special method for handling inout params.
             In this method you can provided the value that the inout param should have
             after execute is called.

             Args:
               $sql    - The sql that this rule should apply for
               $p_num  - The parameter number of the inout parameter
               $value  - The value that the inout parameter should have after execute

             Returns:
               On success: 1
               On failure: undef

             Example:

PRIVATE INTERFACE

         Methods used by the package internally. Should not be called from an external package.

       _clear_dbi_err_errstr()
             Helper method used by the fake DBI::st and DBI::db to clear out
             the $obj->{err} and $obj->{errstr} on each method call.

             Should not be called from an external script\package.

       _set_dbi_err_errstr()
             Helper method used by the fake DBI::st and DBI::db to set the
             $obj->{err}, $obj->{errstr}, $DBI::err and $DBI::errstr.
             This method also handles RaiseError and PrintError attributes.

             Args:
               $obj - Instance of DBI::st or DBI::db
               %args - A hash with the following keys:
                 err     - The numeric error code to be set
                 errstr  - The user friendly DBI error message.

             Returns:
               On success : 1
               On failure : undef

       _set_fake_dbi_err_errstr
       _has_inout_value()
             Helper method used by the DBI::db and DBI::st packages.
             The method searches to see if there is specified a value for a
             inout variable.

             If called in SCALAR context it return 1/undef based on if the
             parameter bound as $p_num has a predefined return value set.

             If called in LIST context the method returns and array with
             1/undef in position 0 which indicates the same as when the method
             is called in SCALAR context. The second element of the list is the
             value that should be applied to the inout parameter.

       _has_fake_retval()
             Method for identifing if a method has a predefined return value set.
             If the SQL parameter is provided
             this will have precedence over the default value.

             If the method is called in SCALAR context it will return 1\undef based on
             if the method has a predefined return value set.

             If the method is called in LIST context it will return a list with 1/undef at
             index 0 which indicates the same as when called in SCALAR context. index 1 will
             contain a reference to the actual return value that should be returned by the method.
             This value may be undef.

       _is_bad_bind_param()
             Method for identifing if a bind parameters value is predefined as unwanted.
             The configuration for the provided SQL will have precedence over the default configured behaviour.

             When called it will return 1\undef based on
             if the provided value should make the bind_param method fail.

CLASS INTERFACE

       get_instance()
             Method for retrieving the current Test::MockDBI instance

         This is basically a copy\paste from the DBI package itself.
         The method is used inside the prepare_cached method

         Mocked DBI->connect method.

         The method takes the same arguments as the usual DBI->connect method.
